To do in Slovenia · Ljubljana
A driver-guide collects you in central Ljubljana and drives you to Postojna Cave and Predjama Castle, with both entrance tickets already paid. Pick it if you want one price that covers everything and a choice of a morning or an afternoon start.
To do in Slovenia runs this one every day, twice. The morning van stops at the InterContinental at 8:00, the City Hotel at 8:05 and French Revolution Square, under the obelisk, at 8:10. The afternoon run moves with the seasons. The listing gives about an hour and a half at Postojna Cave and an hour at Predjama Castle, and both entrance tickets are in the price, plus an audio guide for the castle.
With 1,168 reviews at 4.8, this is the trip most people pick, and the reason is plain: you pay once and nobody asks you for money at the gate. Compare that with the Gray Line minivan, which looks cheaper until you add the park's combined ticket, EUR 49.90 for an adult on the park's own ticket page. Inside the cave the park takes over. You ride the cave train 3.7 km into the mountain, walk a bit over a kilometre with a park guide, and ride back out. Your driver-guide handles the road, the stories on the way and getting you to the right gate on time.
Three caveats from the reviews. The cave walk includes a 200 m climb at a 20% gradient, and guests with bad knees or legs found it hard. Tall travellers complain about the back seats. And one guest who queued anyway called the skip-the-line promise "a lie". There is no lunch stop, so bring food.
InterContinental Hotel at 8:00, City Hotel at 8:05, French Revolution Square at 8:10. Send your meeting point at least 24 hours ahead or it defaults to the City Hotel, Dalmatinova 15. Traffic can add up to 15 minutes.
The park puts Ljubljana less than an hour away by motorway. Your driver-guide talks about Slovenia on the way.
Cave train in, about 1.2 km on foot past the formations with a park guide, train out. The cave stays at 10°C all year.
The castle sits about 9 km from the cave, wedged into a 123 m cliff. Climb through the armoury, chapel and kitchen with the audio guide and hear how the knight Erazem held out for over a year.
Drop-off in central Ljubljana. The order of the two sights can change on the day.

★★★★★The caves are out of this world! I've never seen anything like it. Totally worth it. The castle is interesting but the caves were outstanding.
