Postojna Caves Tours

The Postojna Cave system is Slovenia's most popular tourist attraction, and within an instant of arriving, it is clear why. The cave, formed by the Pivka River, is a 20 km (12.5 mi) long karst cave, and is the most visited cave in Europe. Enter a different world in these incredible caves, and prepare to be impressed.

Your journey begins with a 1.2-mile (2-km) ride into the caves, a thrilling experience in and of itself. See stunning stalactites, stalagmites, calcite, and other incredible geological formations, as well as a wealth of wildlife.

The caves are home to the olm, a salamander-like animal that lives only in these specific caves. There are also many different kinds of insects and other amphibians that are unique to cave environments. The caves also feature an incredible concert hall, famous for its unique acoustical values. The hall can seat up to 10,000 people, and is frequented by symphony orchestras and soloists.

Practical Info

The caves are located about 40 minutes out of Ljubljana, and are accessible by car. Parking is available for a daily fee. If you are without a car, there are shuttle, bus, and train services from Ljubljana. The tour includes a walking portion of about 1 km (0.75 mi), so be sure to wear sensible shoes. Also be aware that it can be slightly chilly in the cave, so appropriate clothing is advised.
