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. Looking for something specific? Jump directly to

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.
