The cave, the castle and Piran

A long day from Ljubljana: Predjama Castle and Postojna Cave with both tickets included, then about three hours in Piran, the old Venetian town on the Adriatic. Pick it if you want the coast added without paying for anything at the gates.

Postojna Cave, Predjama Castle & Piran, Tickets Included

About this experience

To do in Slovenia, the company behind the most-booked cave and castle trip, stretches the same idea into 10.5 hours. Pickup is at 8:00 AM from one of three points in central Ljubljana. The listing runs Predjama Castle first (about an hour), then Postojna Cave (about an hour and a half), then three hours in Piran with a walking tour. Both entrance fees are in the price.

Piran is the reason to book. It's a small walled town on a point in the Adriatic, with a main square and pastel houses, and guests liked the views from the town walls. Three hours is enough for most. One guest found it too long, another wished for swimming gear.

The trade-offs. Lunch comes late: a guest wrote that you don't eat until around 2 pm, so bring a snack. One summer guest reported an air-conditioning failure on a 34-degree day, and another worried about speeding. The listing advises against the trip for travellers with back or heart problems and for pregnant women.

  • Both entrance tickets included
  • About three hours in Piran with a walking tour
  • Three Ljubljana pickup points, 8:00 AM
  • Cave, castle and coast in one day
  • Free cancellation up to 24 hours before

Such a great tour and so easy! The caves were so cool and the castle was neat. Piran is such a beautiful town. I felt like I had enough time to explore the town and see what I wanted to see.

The best part of the tour for me was the cave - it was incredibly impressive! So many different formations; the most I have ever seen. Piran was nice and the views you get from the city walls is lovely even though it was roasting hot.

Tips before you book

  • Bring a snack and water. Several guests say there's little time to eat between the castle and the cave.
  • Pack a jacket for the cave and sun cream for Piran: 10°C underground, often hot on the coast.
  • Swimmers: one guest wished they'd brought swimwear for Piran.
  • The castle audio guide takes time. A guest had to hurry the last few stops, so start promptly.
