Day Trips

From Ljubljana: Postojna Cave, Predjama Castle and Piran Tour

Spend a full day seeing some of Slovenia’s biggest highlights—think caves, castles, and a breezy coastal town—all starting from Ljubljana.

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.”

At Predjama Castle, soak up the wow factor of a castle built right into a 123-metre cliff, then wander through the museum and snap some photos.

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.
