Postojna

By car, Postojna is less than one hour west of Ljubljana on the A1 highway. There are also train and bus connections with Ljubljana. The train station is about 2km (20min walk) from the caves, while the bus station is even closer. The bus from Ljubljana AP that goes directly to the caves leaves 3 times a day at 8:15, 11:30, and 12:00 and costs €5.30 each way.

A free shuttle bus used to run between the train station, Postojna Caves and the Predjama Castle but no longer operates (their website claiming it does is out of date). The caves are a short walk from the bus station. The castle is 9 km away and a difficult walk up hill along a windy road with no foot paths (it is quite picturesque though). During July and August a shuttle runs approximately hourly between Postojna Caves and Predjama Castle, with a 2 hour gap just after noon. Driving is the easiest route but hitchhiking may also be possible during tourist season. The ticket office at Postojna caves can arrange taxi rides - €15 each way (July 2023). This chap runs a taxi service that will take you from the town center to the castle and back for ~€35. (031-777-974)

The main attractions of the area are all run by the same agency. The prices below are if you tour each attraction separately. Some of the attractions can be bundled together to reduce the cost of admission -- the Visitor's Information Center at the Postojna Caves have more information.

• 🌍 Postojna Caves, ☏ +386 5 7000 100, info@postojnska-jama.si. Open every day. The caves were created by the Pivka river over millions of years. The cave system has three levels. The Pivka River flows through the lower level, so the cave is still expanding today.A total of 175 species live in the caves of Postojna. Of these, 115 are troglobionts, which means that they occur exclusively in caves. The most important of these is the olm, which can be seen during the cave tour.As water droplets containing various minerals fall to the ground, they gradually precipitate out the minerals, forming stalagmites, also known as standing stalactites. The stalactites you will see are up to 500,000 years old. The most famous stalagmite in the Postojna Cave is the Brilliant, a 5 metre high, snow-white standing stalagmite in the centre of the cave. Tourists are transported inside the cave by electric train. The train takes about 3.5 km and the guided tour on foot is 1.5 km. From the cave entrance, the train runs through narrow passages, but there are parts of the cave where a cathedral could be built. The cave system includes a concert hall, which has been in use since the 19th century and can host up to 10,000 people. Containing 20 km of underground galleries, chambers and corridors, up to 50 meters high in places. Tours begin with a train journey into the cave system through several chambers before visitors get off and do a guided walk through stalagmite studded caverns. The train then returns you to the surface. The whole tour lasts 90 minutes. Tall travelers beware - the cave ceiling is very low in many parts of the train journey with sharp protrusions from the cave walls, and the train runs quite fast, so keep all bodily limbs (and children) well inside the moving vehicle! Other longer and more strenuous tours ("Underground Adventures") are available to groups of 2-50 people. The caves are damp and chilly (10 C year round) so appropriate shoes and clothing should be worn. €25.80/20.60/15.50 adult/student/child. Start of guided tours is at 10.00, 12.00, 14.00 from October to April and on every hour on the hour between 9.00 and 18.00 from May to September.

Hotels around Postojna cost €60 to €100 per night for two people staying in a double room in a 3-star hotel. There are no 4-star (or higher) hotels in the region (as of 2007). The prices for hostels are significantly lower. Some hotels publish their prices per person but rather than per room, thus if you want to book a double room you may be quoted a price of €35, which means the room actually costs €70 per night for two people staying in it (2 x €35 = €70).
