Postojna lies at the north end of the Pivka River valley and due to convenient transportation routes and its location between Ljubljana, Trieste, Gorizia, and Rijeka has long been the administrative and economic center of the Notranjska region.
Today, Postojna is a modern, clean, and friendly city. It acquired the stamp of a tourist city primarily from the world-famous Postojna Cave, as well as smaller caves in the area such as Otoška jama, Pivka jama, and Črna jama. Only ten kilometers from Postojna, the astonishing Predjama Castle (Predjamski Grad) perches in the middle of a high cliff, exciting the imagination with well-known legends about the medieval robber baron Erazem Predjamski and the siege of the castle that ended with his gruesome death as a result of a servant's treachery.
Postojnska Jama (Postojna Cave) conceals one of the largest networks of caves in the world, with 23 km (14 mi) of underground passageways. A miniature train takes you through the first 7 km (4 1/2 mi), to reveal a succession of well-lighted rock formations. This strange underground world is home of the snakelike "human fish" on view in an aquarium in the Great Hall. Eyeless and colorless because of countless millennia of life in total darkness, these amphibians can live for up to 60 years. Temperatures average 8°C (46°F) year-round, so bring a sweater, even in summer. Tours leave every hour on the hour throughout the year.
