Overview

This small-group tour lasts about five and a half hours and visits two of Slovenia’s main sights starting from Ljubljana. The tour begins at Predjama Castle, which sits on a cliff in the Inner Carniola region. Visitors spend about an hour exploring its chambers and staircases while learning about its famous former resident, Erazem of Predjama. Afterward, the group travels to Postojna Cave. The visit includes a 90-minute guided tour of this extensive cave system, starting with a ride on a mini-train into the underground network of passages, caverns, stalactites, and stalagmites. Postojna Cave features 21 kilometers of galleries and halls and is known for its variety of underground animals, including the proteus anguinus, or human fish. Transport between sites is by air-conditioned minivan, and an English-speaking professional guide accompanies the group. The tour meets at a central location in Ljubljana. Tickets for the cave and castle entrance are not included and must be purchased separately.
