Admire the stunning formations sculpted by natural forces in this brightly lit maze of caves and follow the tunnel to a mysterious cliff-top castle.

The Postojna Cave is an intricate network of tunnels decorated by stalagmites and other natural features. An electric train runs through the intriguing passageways, which lead deep into the hillside before opening up at the site of a magnificent Renaissance castle.

Take a guided tour of the cave system to learn about its bizarre formations. Spot the cave’s olms, which are the largest troglodytic amphibian in the world. The pink worm-like creatures live in water and can be seen in the tour’s aquarium.

Marvel at the incredible cave formations illuminated by brightly colored lights as your train travels past. Take an audio guide to learn more about each of the cave’s rooms, such as the elegant White Hall. Read the Golden Book of Visitors to find out which famous figures have visited the cave. Admire the Brilliant stalagmite, a white limestone rock with a height of 16 feet (5 metres). Water trickling down the natural pillar gives it a shiny appearance.

Find out the fascinating history behind the cave. The Pivka River initially carved this labyrinth. It was one of the first parts of the country to receive electric lighting towards the end of the 19th century. Discover how German forces used the cave to store aircraft fuel during World War II.

Enjoy the illuminated nativity scene during the Christmas season. You can purchase combination tickets that include access to the Predjama Castle, which lies to the northwest of the cave system. Cave tours are held every hour from morning until early evening in summer. Note that the tours are a little less frequent during winter. Most of the tour is taken on foot, so ensure you wear suitable shoes for walking.

The Postojna Cave is on the outskirts of Postojna village in western Slovenia. Buses provide a connection between the town’s main train station and the cave's entrance. The nearby coastal town of Portorož is a 1-hour drive west, close to the Croatian border.

10/10 Exceptional! (13 reviews)
Exceptional experience! The staff is very attentive to every detail and want to make your stay a 5 Star. The chef prepared meals with outstanding blend of tastes, presented eloquently and provided a personal explanation of the courses. Best flavorful meal with rolling hills and old town historic setting. Five Star!!! We also rode e bikes for 60k and found the rides perfect for this activity and safe. Perfect location to hop on and ride along the river to other towns. Perfect location to access Lake Bled with minutes to the city center. Exceptional property. Enormous amount of heart went into developing this property and it shows with an exception 5 star from room, staff, food, amenities. Definitely would stay again!

8.2/10 Very Good! (42 reviews)
We stayed for five nights. Our arrival was miserable. We drove from Split. Our intention was to arrive by 8pm, but due to some delays, we arrived at 9:30pm. The reception had left at 9pm. The front door was locked. There was a note: call a local number to gain entry. Being from Canada, we tried to avoid costly cellular roaming fees and were travelling with data only (eSIM). So we couldn’t call the number. After trying to contact the property via Expedia (which failed), we finally enabled roaming (expensive), and were able to speak to the property and they talked us into locating keys in a lock box. The room we got was room 7…one of three attic rooms. We had to lug our suitcases way up to an attic level…the stairs were not lighted…and we finally, using the phone’s flashlight, were able to enter the room. This room was built between roof trusses and beams. To get into the beds required climbing over wooden beams while avoiding hitting one’s head on a slanted wall/ceiling. Accessing one bed required climbing under a steel rod while climbing over a wooden beam. Quite dangerous and not acceptable in terms of safety. We stayed in this room for the first night but insisted that we receive a better room. We moved into room 2, not an attic room, for the last four nights. Note…the photos of the attic room skillfully manage to conceal the hazards. The lower level room was much better. It was nice, but there weren’t enough places to stash belongings/towels, but it was clean & tidy
