Experience the wonderland in the most authentic way by touring parts of the cave that remain closed to regular cave tours. Wearing caving boots and oversuits, fitted with a rope, a headlamp and a helmet, you will venture into mysterious cave depths accompanied by experienced guides. The adventures are intended for smaller groups of visitors who would like to experience more challenging cave passages, break through water barriers, and follow in the footsteps of cave explorers.
Trek through Three Caves
In the period between World War I and II, when the territory of Postojna was part of Italy, three caves of the Postojna Cave system, namely Postojna, Black and Pivka Caves, were connected by means of man-made passages. The construction of man-made passages was a military project and, according to a plan that eventually fell through, the tunnel leading from the Pivka Cave was supposed to continue to the Planina Cave, whose exit was located on the Italian-Yugoslav border. The man-made passage makes it easy to move from one cave to another, which gives you an excellent opportunity to learn about the vast size and grandeur of the Postojna Cave system.
The trek takes two to three hours following an easy trail, and starts with a cave train ride. The guided tour takes place in smaller (3-10) or larger groups (11-30 people). It takes place daily at 12:00, between 23 June and 23 September 2018. Throughout the rest of the year, the treks are possible by prior arrangement. Tickets are sold at the Postojna Cave Park ticket office, the meeting point is in front of the cave entrance. The tour is guided in English only. Extra equipment is not needed.

Postojna Cave and Small Caves
The Small Caves are a 500-metre-long passage inside Postojna Cave. They feature a myriad of cave formations with the Gothic Column attracting most of the attention. The Small Caves have been closed to regular cave tours for the last few decades, which has resulted in an interesting development of new cave formations, the so-called cave pearls – marble-sized spherical formations made of calcite. They are formed by water droplets moving and rotating small fragments, and calcite being deposed around the existing nucleus in concentric layers.
Tours of Postojna Cave and the Small Caves take two hours and a half. The tour path is not demanding and requires no special caving equipment. The guided tour takes place in smaller (3-10) or larger groups (11-20 people).
All adventure tours require an advance notice at least three days before arrival. The rental of caving equipment – if needed – is included in the price.
The Coloured Passage and the Lower Tartar
The Coloured Passage is one of Postojna Cave's larger and most beautiful side passages. It boasts a wealth of cave formations in different shades of colour, which give the passage its name. The Lower Tartar is often flooded and connects the subterranean river Pivka with the central parts of Postojna Cave. The passage has no cave formations, it is however an excellent location for observing the changes caused by the Pivka (the heights of past water levels, changes in river banks, deposits etc.). The path leads past an underground lake. You may get lucky and see olms in their natural habitat.
The tour of the Coloured Passage and the Lower Tartar takes between three and four hours. The tour trail falls into the medium difficulty level and is not suitable for children under the age of 15. Guided tours take place in groups of three to ten people.
Warm clothing is recommended, i.e. long-sleeved tops, long trousers, warm socks and some spare clothes.

Adventure in the Cave under Predjama Castle
The Cave under Predjama Castle is the second longest show cave in Slovenia. It is spread over four floors, which are – except for Erazem's Passage – interconnected.
Visitors who would like to see the Cave under Predjama Castle at a more relaxed pace and not as part of regular guided tours can opt for a walk to the Wind Hole, a narrow passage with a strong draught. The easy trail takes one hour to walk and is also suitable for children aged 6 or older. The Wind Hole can be visited by prior arrangement from May to September.
A visit to the narrow Erazem's Passage, which allowed the besieged knight contact with the outside world, is suitable for more daring visitors as it requires some climbing skills. The exit is on the plateau above the cave. A one-hour tour is possible only in a group of two to five people. The tour trail falls into the medium difficulty level and is not suitable for children under the age of 15. Erazem's Passage is open by prior arrangement from April to October.
The bravest visitors can also go on a tour of the Eastern Passages, which takes between three and six hours. A demanding and strenuous caving tour to the river Belščica siphon is possible only in groups of two to five people and is not suitable for children under the age of 15. The Eastern Passage can be visited by prior arrangement from May to September.
