To do in Slovenia · Ljubljana
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.

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.
Choose one of three central pickup points when you book.
The castle in the cliff, with your ticket already paid.
Cave train in, a walk with the park's guide, train out. 10°C inside.
A walking tour of the old town, then free time for lunch, the walls or the seafront.
Drop-off in central Ljubljana in the evening.
★★★★★This tour was fantastic! The caves are beautiful and the castle is very unique. The timing at each location was perfect. Views at Piran were gorgeous. Our tour guide was fabulous!
★★★★★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.
