The Postojna Cave System is a jaw-dropping experience. It’s a series of caverns, halls and passages some 24 km long and two million years old.

With over 1 million visitors each year, the amazing Postojna Caves are Slovenia’s most popular tourist attraction. Read our detailed tips about the best time to visit and how to avoid the crowds:

Avoiding Tourist Crowds

The tours are equally crowded throughout the year. The reason for this is the fact, that fewer tours being offered in offseason. Check the Postojna Caves Timetable. This usually results in the same long waiting lines at the ticket counter and equally large groups in the cave (up to 100 visitors per tour guide) regardless of the season. However, the months of late June until August are by far the most crowded ones. To enjoy a more pleasant and hassle free visit at any time, follow our tips:

Book Online:
It’s much better to buy your tickets online in advance: Online Tickets. Then you can skip the long waiting line at the ticket counter in the cave park. You still have to convert your ticket into a scannable barcode. However, there is a separate counter (Group/Online) for that with almost no people in the line. It saves you between 30 - 50 minutes of waiting in the standard ticket line. This also applies if you bought the ticket in advance at other places.

Book an Early Spot:
Book the first spot available at 9:00 AM (10:00 AM in the off-season). It’s much less busy at the entrance and in general. Later all the large tour buses arrive throughout the day. Additionally, the chances are at least slightly higher that you can join a smaller group in the cave with less than 100 visitors. (The English language groups are always the largest. Join another language group if you speak one of the other languages)

Arrive 30 Minutes Earlier:
If you bought tickets for the 9:00 AM slot, be at the Cave Park around 8:30. It takes up to 10 minutes to walk from the car park to the gates. You’ll also have time to use the restrooms and be the first in line for the electric train.You have to be there 10 minutes before your tour starts anyway

Another great option to getting away from the crowds are the Adventure Tours. These are always done in small groups (3-10 or 11-20). The price for the easiest tour is only 40 EUR, compared to 26 EUR for the regular visitor tour. Read more details about these tours in the description section below.


Regardless of the outside climate, the cave has a constant temperature of 8-10°C (46-50°F) throughout the year. However, you are probably planning more activities besides the cave. If you prefer pleasant temperatures visit between May and September (you might want to avoid the extreme tourist months of July and August for your Slovenia visit).

Cumaca Cave is located close to the Cumaca Village. It is a gravel, bumpy road and a 4x4 is necessary. It is advisable to get a guide for this trip. A permit for entering the cave is required.

To spot the oilbirds a guide is necessary to find the muddy trail to the Cumaca Cave. It depends on the water level if you can walk into the cave. The oilbirds are nocturnal, and at daytime, they rest in the cave.

Dry Season - Weather

Best months for Trinidad and the hike to the cave are January to May and September. Rain can always occur in Trinidad. The trail to the cave can be muddy even in the dry season but worth to do. During the rainy season, the water level of the Oropouche River can be too high for safe walking.

Benagil is famous for its caves, the coastal walk to several beaches and the lighthouse. It is a stunning walk from Benagil to the famous Praia de Marinha.

Inside of the famous Benagil Cave is a beach which is much bigger at low tide. Swimming into the cave can be quite challenging especially during rough seas! Swimm with a board and in a group not alone.  Check the tides first before swimming! Anyhow, you need to be an experienced swimmer. An alternative is a boat trip to the existing caves at the Algarve.

Avoiding Crowds and Best Time for Swimming

Best months for swimming are June to September with pleasant sea temp.  July and August are the peak season; Prices increase and beaches are pretty crowded. The Portuguese school holidays start mid-June and last roughly until the first week in September depending on the school. Therefore, the ideally times with fewer tourists and pleasant weather are the first half of June and at the beginning of September but even October is an excellent month. Bring a neoprene shorty for longer swimming though the sea temperature is around 21°C / 70°F during summer until October and 20°C / 68°F in June.

Birding at National Park Zapata is outstanding. We did this guided tour twice with different guides at different months. A car is necessary to go to this three different places.

The best time of day for birding is the morning. Don't go too early, otherwise mosquito might eat you up.

The best months are November until April in the dry season. Rainy season from July until October is not recommended, as areas can be flooded. Shoulder season May and June, showers may occur but easier to find a casa without booking in advance. July and August are the Cuban school holiday.
