Top Koper Rail Tours

Explore a maze of underground caverns and a dramatic cave fortress on a tour from Portoroz to Postojna Cave and Predjama Castle. Combining the two adjacent destinations makes the most of your time on the road, but coordinating transport with a busy sightseeing schedule can be a headache; take advantage of a flexible departure time, then relax and enjoy the view as you discover one of Slovenia’s most scenic areas.
