This relaxed, well-organised trip to Postojna Cave, Predjama Castle, and Piran, comes with comfy round-trip transfers and a friendly English-speaking guide/driver to keep things easy and informative.

At Postojna Cave, hop on the famous cave train, wander through huge underground chambers, and keep an eye out for the rare “human fish.”

Spend time wandering Piran’s charming old town, stroll along the seaside promenade, enjoy views of the Adriatic, and stop for a coffee or gelato in one of the lively coastal squares.
