Postojna, Slovenia

The town of Postojna would be an eminently forgettable place were it not the location of one of Slovenia's most popular tourist attractions, the amazing Postojna Caves, whose vast chambers and dazzling formations have been pulling in the punters for nearly two centuries. Despite its role as Notranjska's administrative and economic centre, the town itself is pretty much devoid of character and you'll not want to hang around once you've visited the caves and the Predjama Castle, just a few kilometres away. Located on the main road and rail routes to the coast, the caves are easily managed as a half-day trip from Ljubljana, or as a stop-off en route to the coast.
