Postojna is a town in the Coast and Karst region of Slovenia, pronounced in Slovenian as 'Post-oy-nah'.

- Postojna Caves, +386 5 7000 100. Open every day. 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.

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.
