Rocky Mountain National Park’s 415 square miles encompass and protect spectacular mountain environments. Over 300 miles of hiking trails, wildflowers and wildlife.

Sweet spot months in Rocky Mountain National Park (RMNP) without the heavy summer crowds, open Trail Ridge Road and a good chance of nice weather are late May until early June or September after Labor Day (mid-week) until mid-October. However, snow is possible at both times. September is also great for wildlife because of the elk rutting season (peak mid-September to mid-October). In fall the air is clear and crisp and the skies are blue. Please make sure to read our full season guide below (including monthly weather), seasonal crowd tips, hotel suggestions as well as more useful tips at the end of this article (scroll down!)
 

Top Tip (Very Easy Hikes)

Tip: Venture off Trail Ridge Road to experience the real beauty of RMNP. If you can't do any strenuous hikes but still want to be awed, then take a look this guide on Amazon: Best Easy Hikes Rocky Mountain National Park. It covers amazing hikes for everyone,  even suitable if you visit with small children (like 0.5 miles or 2 miles round-trips). But also hikes which are slightly more challenging. Like John Muir said 'Of all the paths you take in life, make sure a few of them are dirt.'
 

Highlight (Trail Ridge Road & Tours)


The stunning Trail Ridge Road is open from Memorial Day (last Monday in May) until mid-October. The official closing date is October 23, but they often close it a few days before that date. Even in June or September, it’s possible that it’s closed for hours or a day due to snow, often between 8 PM and 10 AM.  Make sure to check more tips for the Trail Ridge Road in our section below the season guide (scroll down).

Special Tour Tip (from Denver or Boulder): If you're staying in Denver or Boulder and would like to experience the Trail Ridge Road as well as the most stunning viewpoints hassle-free, we suggest the Unique Rocky Mountain National Park Tour (from Denver and Boulder). It's an 8 hour day tour which includes driving the amazing Trail Ridge Road as well as other mesmerizing parts of RMNP. The views you'll get to see on this trip are just spectacular. Everything is taken care of, including pick-up service from Denver and Boulder (In case you need a hotel in Denver, check these deals: Denver Hotels)
 

Seasons (Weather/Wildlife/Nature)

Regardless of the season: The higher into the mountains you go, the colder it gets. In general, RMNP is known for its extreme weather patterns which can change very quickly, as well as wide variations between day and nighttime temperatures. Find detailed weather data here: Climate Estes Park - Colorado


 

Spring | April - May


Early Spring in Rocky Mountain National Park

The weather in spring is unpredictable: Up to 70°F (21°C) on one day and a temperature drop together with blizzards on the next day. It varies between warm and cold, wet and dry. Many trails are still snow-covered well into May, often even at the end of May. After a warm April, trails can be snow free in May, but are very muddy. This means you either have to deal with snow or with muddy trails. In general, snowfall is not uncommon in spring. Temperature ranges between 70°F (21°C) and 60°F (16°C). 
 

Summer | June - July - August


Cub Lake in RMNP at Dawn

The most comfortable weather is in the summer months from July to August: The temperature climbs up to 75°F (24°C). However, afternoon thunderstorms can occur and wind is normal. Always prepare for temperature drops of 10-20 degrees Fahrenheit. Keep in mind that the highest elevation trails are snow covered well into June. Wildflowers are in bloom from late June to early August. What to wear in the summer? Always bring layers of clothes, even if you don't plan to hike at higher elevations. A morning can be mild and in the afternoon temps can drop remarkably. Always bring a rain jacket, as well as a warmer long sleeve shirt in your pack. Usually you can start with a short sleeve shirt for hikes or walks.
 

Fall | September - October - Early November


Elk in Rut at RMNP by Mark Byzewski, CC BY

Autumn is usually a great time for a visit. September and October bring clear, crisp air, blue skies, and generally dry weather.  Especially in September it's generally still mild and warm. However, mornings and evenings can be a lot chillier. Always bring a jacket! Early snow is already possible in October. Looking for fall foliage? Leaves start changing colors in late August at higher elevations, peak is around mid-September and the beautiful fall foliage lasts until October in most years at lower elevations. Early October is often still a good time for leaf peeping at lower elevations. At higher elevations the vibrant fall colores will be already gone in October. Elk rutting season begins in September as well and continues through mid-October at least. Like in spring you need to be flexible, check the forecast and bring gear and clothes for various conditions. 
 

Winter | November - March


Dream Lake in Winter by Max and Dee Bernt, CC BY

Winter in RMNP means snow and arctic conditions. However, lower elevations on the east slope of Rocky Mountain National Park are usually free of deep snow. The west side of the park experiences more snow, less wind, and clear cold days during these months. Most high country overnight trips require gear suitable for freezing temperatures. Skiing and snowshoeing conditions are best in January, February, and March. There are lots of other exciting activities in Winter: Sledding at Hidden Valley, Winter Wildlife Viewing, Ice Climbing and more. Visit NPS Rocky Mountain Winter Activities and 20 Things To Do in the Winter. Trail Ridge Road: While it's closed in the winter, keep in mind that you're allowed to drive the first 8 miles until Many Parks Curve overlook. Depending on weather conditions of course. 
 

Avoiding Tourist Crowds


Lookout (RMNP) by C_Phif, CC BY

With over 4 million visitors each year, Rocky Mountain National Park is one of the most visited Parks in the U.S. Expect the most crowds in summer and fall. The busiest months are June until August, with heavy crowds in July/August. During the week it starts to thin out after Labor Day in September (first Monday in September), but not on weekends. Also, try to avoid National Public Lands Day at the end of September. Entrance to to all National Parks is free then and RMNP will be extremely busy on this day/weekend!! Visiting mid-week in September means less crowds as well as enjoying elk rutting and pleasant fall temperatures at the same time.

In general from July through September: Avoid weekends and/or go early in the morning to beat the crowds. In the peak months arrive between 7 and 8 AM to get a parking spot. Usually, it starts to get busier after 9 AM. Especially popular entrances like Estes Park or trailheads like Bear Lake Trail are extremely busy. In general, the west side (Grand Lake) is less crowded than the Eastern side (Estes Park Entrance). Regardless of the month, season or entrance: Go as early as possible, head out on a trail, hike a few of miles from the busy areas and you won’t see too many others.

Yellowstone's abundant and diverse wildlife are as famous as its geysers.

Where animal sightings happen, depends on habitat preferences, weather and seasonal cycles of movement. Still, it's often a matter of luck but you can increase your chances by following our monthly guide. Read our full guide below and find out which animal can be seen in which months and season (spring - summer - autumn - winter). And if you want to make the most out of your wildlife visit, consider this incredible private tour: Private Yellowstone Wildlife Tour (with extremely knowledgeable, friendly, and professional tour guides. You'll remember this special tour forever!)

April - Early June (Spring)

Most animals can be spotted in or near the valleys. It's the time for baby bison, baby moose, baby bear, baby elk and many more. Also a good time to spot wolves and grizzly bears. Grizzly sightings occur mostly at night, dawn and dusk. A great grizzly bear spot in spring is the shores of Yellowstone Lake. Gray wolves are often seen in Lamar Valley and Hayden Valley.

 

Mid-June - July - August (Summer)

Bears and other animals leave the valleys and head for higher areas in June/July. But still, visitors often report bear sightings throughout June. Later in July and August the chances to spot grizzlies or black bears in the valleys are very low.  However, bison are still there, starting to rut in early August. Warm, great weather but also peak tourist months. 

 

September - October (Autumn)

Animals return to the valleys. Elk rut throughout September. The fascinating rut can be witnessed up-close in Mammoth Hot Springs, near the northern entrance. Together with amazing fall colors it’s one of the best time to view or photograph almost every animal including elk, moose, bighorn as well as wolves and grizzly. Visitor wise it gets slightly less busy in September after Labor Day weekend. However especially weekends are still busy. In late September/early October the crowds start to dissipate.

 

 

November December- January - February - March (Winter)

Winter, a magical time and least crowded. Most animals are in or near the valleys. Some can be spotted near the steaming geyser basins. Winter is the best time to view wolves. You can also observe bison, elk, bighorn and others. Another great time for photographers, since animals are easier to spot against the snow. Grizzly bears can't be spotted, since they hibernate in winter until mid-March.

 

Time of Day

The best time of day for wildlife viewing is either dawn or dusk: Animals usually feed during the early morning and in the evening. That's why they're often more visible at these times as they're up and moving around. In general dawn is even superior: Be at the valleys just before at sunrise and stay until 9 AM. It's also less crowded. However, dusk is also great, particularly for elk viewing in Sept. Sunrise - Sunset Yellowstone

Avoiding Tourist Crowds

Yellowstone National Parks gets heavily crowded in the peak summer months. If you plan a summer visit, book your hotel well in advance. 

The most crowded months are June, July and August: Congested roads, overflown parking lots and the popular places are packed: Old Faithful, Grand Prismatic Spring, the Grand Canyon of the Yellowstone, Mammoth Hot Springs. The month of May is still moderate visitor wise. However, it gets very busy on Memorial Day. Later in September visitation starts to drop off after Labor Day weekend. However, it's still busy, even more so on weekends. In late September the crowds start to thin out. In October it's getting a lot quieter again.

How to avoid the crowds during peak months? Arrive early! The rush hour in YNP starts between 9 and 10 AM. Get up as early as possible!  Another way is to dodge the crowds is by staying late: The main attractions are packed between 10 AM and 4 PM. Get there later, as it doesn't get dark before 9 PM anyway. Another big advantage when arriving early or staying late: You'll get to see more wildlife at dawn or dusk (see above). Extra tip: Check the official NPS Webcams a few days before you arrive during certain daytimes. 
 

Weather

There is one word which is true for Yellowstone's weather: Unpredictable! Temperature drops and rain can happen almost any time in spring, summer and fall. Thunderstorms in summer are common in the afternoons. Bring layer of clothes and always rain gear.

If you'd like to avoid snow completely, then don't visit before May/June. It still can snow in June at some places but it will melt very quickly. By late May the valley floor is usually snow free. In higher elevations you may still see some snow in late May and June. That's important to know if you go hiking. After the summer you can expect the first real snow in October. As a local expert says: 'You can count on snow on the ground in Yellowstone by Halloween!'. However, never let the snow stop you from coming. October is an excellent month: Quiet and still so much wildlife to spot! In spring late April and May are our preferred months, regardless of the snow. Just keep in mind that until late April it still can feel like winter!

Welcome to our unique Denali guide (updated 2019) with tips for each month, hiking insights, and everything you should know about the bus transport service. When is the best time to visit? Denali is open year-round. However, main activities and tours are being offered in summer only. Shuttle busses will get you into the wilderness from May 20 until mid-September. Now, read our season guide below the quick navigation or jump directly to the top hiking and bus tips.

Keep in mind that the temperatures vary depending on the elevation and the part of the park). Check the Denali Webcam at Wonder Lake and read on for more details about a summer, winter, spring or fall visit:


The best time to experience amazing fall foliage in Denali: Late August/early-September
 

Mid-May - late May (spring): May is the driest month and the weather starts to get warmer. Average high: 52°F (11°C). Most tours and the shuttle bus service start around mid-May. However, some snow has still to melt. As a result, the deeper parts of the park are often not fully accessible. Rates are low and there are no crowds.

June (late spring, summer): June is also a very dry month and temperatures climb. Average high: 66°F (19°). Flowers are in bloom and you get the most hours of daylight (Sunrise-Sunset Denali). After the first week of June, the park is usually fully accessible. Early June until mid-June is a great time before it starts to get crowded with tourists coming from cruise ships and everywhere else. Drawback: Mosquitoes are an issue from June until the end of July.

July (summer): July is the warmest months with temperatures climbing to 70°F (21°C) and still a lot of daylight (18-19 hours). There is slightly more precipitation than in June, but no need to worry about long periods of rain. July is the peak month in terms of visitation. Again, small drawback: Mosquitoes are still an issue.

August (late summer): It's still pleasant. However, temperatures already start to drop slightly but it's still a great month temperature wise. Average high: 62°F (17°C). Also, there are slightly fewer daylight hours in August (16-17 hours). August has the highest average precipitation of all months. However, nothing to worry about. You need to bring rain gear regardless of the month. In terms of visitors, it's still very crowded.

Early September - mid-September (early autumn): As temperatures drop it will be cooler in September and there is also less daylight (11-14 hours). Average high: 50°F (10°C). However, it's still a great month to visit as the temperature is still pleasant and all services are being offered until mid-September. After Labor Day Weekend (beginning of September) the crowds dissipate as well. You'll enjoy a much more peaceful park. Looking for the leaf color explosion? Fall foliage starts early in Denali. The peak time for the beautiful fall colors is usually the end of August and early September.

Mid-September - mid-October (autumn) and April - early May (spring): Most services are shut down, restaurants, hotels, and shops are closed from mid-September to mid-May. However, the shoulder season can be quite rewarding as you can experience the 'real' Alaska. In the fall temperatures can still be pleasant or already freezing cold in October. Always check the weather forecast. In fall and spring, you need to rent a car as the shuttle service is not available. More helpful details about visiting in shoulder season: Fall and Spring Visit 

Late-October - March (winter): It gets freezing cold and it's time for Winter Activities. Including skiing, winter biking and snowshoeing. Temperatures are ranging from -40 degrees Fahrenheit and colder, to high 20s on warm days.


Avoiding Tourist Crowds

The summer months experience the highest visitation. Check out the visitation chart below, then our tips for enjoying  a more peaceful visit to Denali National Park.

  • Shoulder Weeks (late spring/early fall):
    To avoid the most crowds at the popular spots (entrance areas, bus tours, visitor centers, famous spots) during peak season, still use the shuttle bus service and enjoy mostly pleasant weather: Visit during either in the very short late spring or early fall season: End of May until mid-June or early September (after Labor Day) until mid-September.
     
  • Popular Tours in Shoulder Weeks:
    The very popular day tours which do not include hiking like the Tundra Wilderness Tour or the Kantishna Experience Tour are usually fully booked during peak months. During shoulder weeks (see above) there is a good chance that a tour bus is less than half full. That means you can spread out. The tours usually run from mid-May until mid-September (Kantishna from early June until mid-September). Read below for more info on bus tours.
     
  • Own Activities / Trail Hiking:
    You can avoid crowds in peak season by planning your own activities. And even if you only drive to Savage River (by free bus shuttle or with your own car) for the short hike and to spend time there, you'll avoid tourist groups by starting early. Check the list of trails: Denali Trail Details. Always start early, and you'll avoid the crowds. If you take a shuttle bus: Make an online reservation and book the earliest departure.
     
  • Off-Trail Hikes/Walks:
    Even in the summer, it's quite easy to get away from every group of tourists and spend time in solitude: Book a transit shuttle bus early in the morning departing from the WAC (Wilderness Access Center). Get off the bus wherever you like and start hiking or walking. Regardless of your fitness level or age! If you feel intimidated, you can stay close to the park road the whole time and still experience stunning wilderness and wildlife. Get back on the bus to WAC whenever you like for free. Find more details about easy off-trail hikes (even short 1-2 hours hikes/walks) below in the hiking and shuttle text section.
     
  • Stay at a Hotel Outside the Park:
    The entrance area is always filled with thousands of people in the summer. The same applies to the hotels very close to the entrance (Princes Lodges, Bluffs Hotels, …). The easiest way to avoid those heavily crowded areas is to take advantage of the more quiet lodging alternatives in Healy (17 Minute Drive - Google Maps). You'd need a rental car in case the hotel doesn't offer a shuttle service (UBER is also available now), but the hotels there are also less expensive. Check the best prices and book well ahead: Healy - Recommended Hotels
 

Wildlife / Flora / Northern Lights

The best time of day to spot wildlife is in the morning or late afternoon/evening. Being on a bus long enough increases your chances. Best season is during the warmer summer months. There is not much wildlife in the winter due to hibernation. Denali also has a rich and amazing flora. Wildflowers begin to bloom in early June till late July. How to spot the Northern Lights? Since the Denali region is almost free light pollution,  it's an excellent area to see the aurora borealis (Northern Lights).  The sky must be dark enough and clear. With a partly clouded sky, it's less likely to experience it. Time of day? Usually, you can start looking after 1,5 hours after sunset. It's possible to see the Aurora here between mid-August and early-May. However, the highest chance to spot Northern Lights is in March/April and September/October.

We also collected the the best tips for short hikes and walks, as well as insider tips on how to avoid the crowds during peak season and fall color tips (direct navigation):


Season Tips for Acadia National Park

May - June | Spring 

Both months bring warmer and drier conditions. However, in May the trees aren't green yet and it might be too cold for water activities. Temperatures: Up to 51-75°F / 11-22°C in June. It’s pleasant weather for hiking and other outdoor activities. The downside is, depending on how rainy it has been before, there are biting bugs from mid-May until mid-June. Many facilities are open and May is still a quiet month, except for Memorial Day Weekend (end of May). In June it gets already busier but not as crowded as in July and August.

July - August | Summer 

Warm, most pleasant temperatures. Peak season. It gets very busy, even more in August. Booked accommodations, waiting lines, crowded parking lots, congested Park Loop Road and busy view points. To avoid the crowds during peak season, get to the park early in the morning or in the late afternoon around dinner time. More tips on how to avoid the crowds can be found below. 

September - October | Autumn - Fall Colors 

Early September after Labor Day until mid-September is a nice time to visit the park: The weather is pleasant (49-68°F / 9-20°C), it's not super quiet, but the heavy summer crowds are gone and the 'leaf peeping' crowds haven't arrived yet. It gets very busy again from late September until mid-October as thousands want to see the leaf color explosion in fall. The best time to experience the amazing colors is usually mid-October. Tip: Read our '7 Must-Know Fall Color Tips' below in the main text. Book ahead of time if you need accommodation during the ‘leaf peeping’ weeks. After Columbus Day in mid-October crowds dissipate and rates drop. This is another sweet spot time without the heavy crowds. The last week of October ist often still ok for watching the fall colors, but it also gets cold and rainy. 

November | Late Autumn 

Even in early November, it's usually too late for spotting the beautiful fall colors. Temperatures drop (33-48°F / 1-9°C ), try to visit until mid-November. It’s colder, but still worth to visit the park without the crowds, almost in solitude. Many facilities are closed though. Definitely, drive the Loop Road which is usually still open in November.

December - March | Winter 

It’s off season and very cold. Average temperature in January: 14-32 °F / 0-(-)10 °C . Time for snowmobiling and skiing. Most hotels, restaurants, campsites and attractions are closed. The scenic Park Loop Road is also closed from December until mid-April (weather dependant). More winter activity info: NPS Acadia Winter Activities

April | Early Spring

Many visitors would say that April ist is still not pleasant with melting snow and muddy ground. Average temperatures are between 25-41° F / 1-11° C. However, we'd definitely recommend this month. You might be wondering why? First of all, from mid-April the scenic Park Loop Road usually opens. Second, it's still quiet without any heavy crowds of other tourist. You'll have no issues with parking and can enjoy some places almost in solitude. While there are still signs of winter, the scenery is just breathtaking. Some say the views are even more amazing with no leaves on the trees. Bottom line: We think a visit between mid and late April is a great time!


Weather

Regardless of monthly temperatures we described above, you should know that in Maine the weather can change dramatically during the year. However, temperatures along the coast in Acadia N.P. are moderated by the ocean. In the graph below you'll find the average monthly highs. Least rainfall is in June, July and August. But still, keep in mind that the weather is often unpredictable and can change instantly. Be prepared for rain at any time.

 

 
Avoiding Tourist Crowds

It gets crowded in Acadia National Park in summer and fall. A sweet spot time without the heavy crowds but mostly pleasant temperatures used to be those two weeks in September (after Labor Day until mid-September). However, it's not that quiet anymore during this time, especially in the recent years as visitation increased. Otherwise, there are two different sweet spots weeks with mostly pleasant weather and few visitors: A) The weeks after Columbus Day (mid-October) until early November.  B) Early June until mid-June: Although it's already busy at places like Bar Harbor, visitors report that most hiking trails in the park are not crowded.

 

However, if you plan to visit during the summer and leaf peeping time in fall, we have three great tips to avoid crowds:

1. Be Early or Late:
The majority of people tend to visit Acadia from mid-morning to afternoon. Get up early and try to be at the most visited spots or trailheads before 9:00 AM. Usually, the crowds start to arrive around 10:00 AM. Incredibly popular spots like the summit of Cadillac Mountain can be crowded earlier. Be there at 8:00 A.M. and you'll dodge the heavy crowds at the top. Another advantage to visiting early is the great light for photos and the higher chance of spotting wildlife. Check out this great Ranger Early Bird Video. Alternatively, visit the favorite spots later around dinner time or head out on a short trail just before sunset. Just after 5 P.M. is a perfect time since most are heading back for dinner around that time. However, make sure to be back when there is still daylight. It's too dangerous to hike in the dark.

2. Visit Quieter Areas:
Head to the less traveled places and trails. On the 'quiet side' of Mount Desert Island west of Somes Sound, try out Acadia Mountain Loop or the Beech Cliff Trail (see below in the hiking section). Or you could head to Schoodic Peninsula (Google Maps) on the mainland, or the quietest side of Isle au Haut, accessible only by mail boat.

3. Use the Shuttle:
If you are visiting between late June and Columbus day, use the free Island Explorer Shuttle. It takes away all the worries of full parking lots at trailheads and congested parking areas at popular places like Cadillac Mountain or Bar Harbor. There are bus stops at all well-known places. They even added one for the trailhead of Caddilac North Ridge Trail (see below in the hiking section). Additionaly, you can always ask the bus driver to let you off, even if it’s not an official stop.

Sitting at a relatively high elevation of 8,000 to 9,000 feet, Bryce Canyon National Park is colder than any national park in Utah including Zion, Canyonlands and Arches. Summer temperature is pleasant and mild with little fluctuations. Night time in spring and fall are chilly but winter is the coldest with plenty of snowfall. Remember to pack your warm clothes when planning your trip to Bryce Canyon National Park anytime of the year. Monthly average maximum temperatures:

More details: Bryce Canyon Climate

Spring (March – May): Weather during spring transition from cold to mildly warm. Nonetheless, visitors still need a jacket particularly in March and April. This is the time to see snow melt from the higher elevation mountains surrounding this spectacular park. However, especially March is still considered a 'winter month' with snow and often unpleasent temps. April is the time when most Bryce experts consider going: The snow is melting and it's the first 'warmer' month as temperatures are getting more pleasant in April.  It doesn't matter that the trails are still muddy and that’s it's unlikely to see flowers. Also, keep in mind that nights in April and May are chilly. 

Summer (June – August): Experience pleasant days and cool nights during summer. The best weather is in July, the warmest month. Rainfall during mid to late summer comes as afternoon thundershowers. These are also the peak tourist months with heavy crowds.

Fall (September – October): Especially September is a great month with pleasant temperatures, blue sky, clear and crisp air. However, weather can be unpredictable and fall nights can be relatively chilly. It is possible to experience some snowfall in October.

Winter (November – February): Winter is the coldest time to visit Bryce Canyon. One will experience lots of snow between January and February, making it ideal time to enjoy snow activities such as skiing and sledging. Much of the area experience snowstorm from October through April. The coldest month is December. Few facilities and amenities will either remain closed or reduce their operating hours.


Avoiding Tourist Crowds

The park is attracting over 2.6 million people annually now (2018). Summertime is the peak tourist season. Quieter times are winter, early spring and late fall. In September, the crowds start to thin out slightly after Labor Day (first Monday in September). However, not on weekends, as they are still packed in September.  June, July and August bring the heaviest crowds. In May it already starts to get busy, especially on weekends.

To avoid the crowds, start your day’s exploration early and go mid-week if possible. Finding the perfect parking space can sometimes be challenging especially at the view points along the scenic drive. However, you can find a nice parking spot just few kilometers away from the more packed ones. Special Tip: If you want to park your car at Sunset Point (limited parking only), arrive there around 7 a.m. A park ranger even suggested 6 a.m.! Otherwise it's better to use the shuttle (see below). Hiking enthusiasts should also start very early as most hiking trails will be packed later. The family friendly and moderate trails are packed in high season: Rim Trail, Queens Garden Loop, Navajo Loop, … You can find solitude, even in peak season, on the more strenuous day hikes like Fairyland Loop and Peekaboo Loop. Especially if you start early. Looking for very easy, short hikes or walks? Read our guide with the 5 best hikes and walks at the end of this article.

Season Guide

In peak seasons (late spring until early fall) the cave draws big crowds, even more in the busy summer months. Each year, about 2 million visitors come to the park, with almost half a million of them taking a cave tour. Read our seasonal cave tour breakdown (shoulder season, high season, low season) and take a look at our tips to avoid the crowded tours in peak season. Please note that there are different tour schedules available for each season and that the number of participants allowed for each tour varies (up to 120). The visitation chart below contains official 2018 data. It gives you a nice insight about the busiest months at Mammoth Cave:


March - April - May | Spring (Crowded Tours): Early March is often still a good time crowd-wise. From mid-March until May the tours get more crowded, especially on weekends and public holidays (Memorial Day). Making online reservations is recommended. To ensure a slot for your desired tour, we suggest booking 1-2 weeks in advance, although for many tours it's sometimes possible to make reservations 1-3 days in advance only during the spring. Spring 2019 Schedule — March 10 - May 25

June - July - August | Summer (Very Crowded Tours): During peak summer months, the cave tours are heavily jammed. However, especially in June it's possible to get into a less crowded tour if you book an early morning spot on a weekday (Mon-Tue). Either way, making reservations is strongly recommended and often required to get into your desired tour. For the rare tours with very few participants, like the Wild Cave Tour, we highly recommend booking 3-4 weeks in advance, as it sells out real quick. Summer 2019 Schedule 

September - October | Fall (Crowded Tours): After Labor Day weekend (early September) the crowds at the park thin out slightly at least, and not every tour is sold out in advance. However, it's still not quiet at all and making online reservations is recommended even during shoulder season. 

November - February | Winter (Uncrowded Tours / Quiet Time): November and December are much quieter months.  January and February is the quietest time in the park. During both months there is a possibility, that you may have a mid-week tour nearly to yourself. 'Walking along Broadway without anyone else is a surreal and otherworldly experience.' You'll also enjoy lowest hotel rates in winter. Winter 2018/19 Schedule
 


Avoiding Crowds and Waiting Lines

Since the cave temperature is at a constant 54 °F (12 °C) year-round, you may just visit in the off-season in winter (see above) or at least during shoulder months, in late fall or early spring. In the summer, the whole place is jammed with tourists, particularly between 10 a.m. and 2. p.m.

However, if you'd like to visit in the summer months or maybe you can only visit then, we got you covered. Choose from one or more of our 3 tips to dodge the crowded tours:

  1. Book the Earliest Tour Spot: Book one night at a close hotel (see the tips below the weather details). Then you use the NPS online reservation (click on the current schedule) and book the earliest tour spot before the buses arrive: 8:30 a.m., 8:45 a.m., 9:15 a.m. (depending on the tour). Book a few weeks ahead of time to make sure the slot is available. Additionally try to go mid-week (Mon-Tue) and not on the weekends. Even those early tours can still be crowded (full) at times but the whole park is a lot quieter in the morning without the masses of tourists arriving via buses.
  2. Book a Tour with Fewer Participants: The number of people allowed on a cave tour varies by tour. The 'Domes and Dripstones Tour' for example allows 118 participants, which results in quite a crowd when fully booked. The Frozen Niagara Tour allows 'only' 39 people. Combine this one with an early morning time slot (see above)! However, the best tour to avoid the crowds is the Wild Cave Tour: An intense and very strenuous 6 hour drive for spelunking enthusiasts. Up to 14 participants only. 
  3. Use Another Parking Area: If you happen to arrive when everything is busy, do not use the parking lot in front of the Visitors Center. It's ridiculously crowded. Just park in the overflow parking at the Lodge (turn right before the Visitor Center). Walk through the Lodge and cross the bridge that takes you to the Center.
 
Weather (For Camping) | Cave Temperature

The cave has a constant temperature of 54 °F (12 °C) throughout the year, regardless of the outside weather. However, winter temperatures can be below freezing at entrances. In most areas of the cave, you'll be comfortable if you wear long pants and take a sweater or jacket with you.

Outside Weather: Even with the consistent year-round cave temperature, the outside weather shouldn't be overlooked. Not only by camping visitors (jump to the campsite section). In general, the climate around Mammoth Cave National Park is moderate with warm summers and pleasant spring and fall temperatures. Winters are mild and rarely harsh.

Spring Weather (March, April, May)

Spring is a pleasant time to visit the area, although the weather can vary a lot from day to day. In March the average highs already reach 61°F (16°C), in April 72°F (22°C). The nights are usually still chilly during March. In May it gets even warmer. May is also the month with the highest precipitation throughout the year. In general, rain is somewhat common during the spring with 8 to 9 days of precipitation per month. Also keep in mind that the weather is unpredictable, especially in spring. An afternoon can go from clear and sunny to rain or thunderstorms within two hours. Campgrounds open March 1 (see below). The campgrounds are not too busy in the spring (except for spring break and maybe weekends). Due to more precipitation, a rain fly is highly recommended for camping.

Summer Weather (June, July, August)

In general, the weather is quite stable compared to spring and other seasons. Summers outside Mammoth Cave are usually sunny, hot and humid. Daytime high temperatures often pass 90°F (32°C) in July and August. The downside is the high humidity between mid-June and mid-September. Especially from early July until mid-August / late August it gets really muggy, which might be uncomfortable for some visitors. On the other hand, the less humid and lower cave temperature comes in handy during those muggy summer weeks. If you're not bothered by the high humidity, the summer months are great for camping. Big plus: Thanks to the bats, you don't have to deal with mosquitoes at all.

Fall Weather (September, October, November)

Autumn weather can also be unpredictable, but not so much as in spring. In September it can still be humid, although not as muggy as in the summer months. The average highs reach 83°F (28°C). October is still pleasant with temps up to 72°F (22°C). In November it gets cooler but it's still mild with average highs of 60°F (15°C). Locals say that November weather can be nice most of the times. The campgrounds are significantly less crowded compared to summer. First signs of turning leaves are often in early October. And a good chance to catch the beautiful peak fall foliage colors is typically from mid to late October

Winter Weather (December, January, February)

Although it gets colder, the winter months are rarely harsh. However, ice storms in January and February are possible, which may cause difficult driving conditions. The snowy period usually starts early December and lasts until mid-March. Most snow falls in January and February. Although the cave temperature is constant year-round, it can be freezing in the cave entrance area in winter. In winter whole Mammoth Cave becomes a warm refuge and the quietness in the park area makes up for the lower outside temperature.
