· Show cave and cliff castle, one guided day
The cave train rolls into the hillside before the walking route begins, and that ride alone sets Postojna apart from other show caves. Inside, lit galleries open onto stalactites and stalagmites that grow at a pace measured in centuries rather than years. Predjama Castle completes the pairing, pinned to a cliff face a short drive away, a fortress with rooms carved back into the rock and a siege story still attached to its walls. Tours from Trieste fold both stops into one day, with the drive and the border handled for you.
from $146Includes transport from Trieste, entry to Postojna Cave and Predjama Castle, with a guide. Check availability →
