Wonderful tour. The caves...

Wonderful tour. The caves are amazing to see (just remember warm clothes). Rachel provided excellent commentary during the journey to/from the caves with interesting insights into the local area and local history. Everything seemed very well organised and we were met at the cruise terminal. Very safe & modern coach driven by Peter. Definitely recommend.

Lynne_L, Aug 2026

Experience great, logistics not as great.

The cave experience itself was fantastic. The wait before even getting in line to get on the train was frustrating. We left the port at 10 am and returned at 4:30. We were able to go into the castle immediately. The guide told us the drive to the cave would be a half hour. It was really 45 minutes and, when we got there, we had an hour wait before we could get in line for the train. We waited in the train line an additional 20 minutes.

Slovenia in One Day: Small-Group Bled, Postojna Cave & Predjama

Action packed day

Wow! What an action packed day seeing the countryside and some of Slovenia’s exceptional sites! My husband broke his foot before our trip but still was able to enjoy the tour and sites. The driver/guide was knowledgeable and made it interesting with some tales and humor while driving. Know that He does not accompany you on the site visit. It’s a very worthwhile tour if you have limited time in country.
