Postojna Cave and Predjama Castle - Entrance Tickets Included

Margaret_K, Sept 2026

Postojna Cave and Padjama Castle.

Postonja Cave is not to be missed. And the castle is very unique. We’ve traveled a lot and never seen anything quite like either experience. Tour guide was great and shared a lot of info on life in Slovenia. However, Van needed seat belt and air conditioning repaired. Also the van interior was not cleaned after previous days tour.

A great trip visiting two must see places.

A great trip combining two excellent places. Mini bus very comfortable and plenty of space. Brilliant communication and clear instructions from Viator from booking til the morning of the trip. Easy to find meeting point. Caves were incredible and the castle very interesting. Well worth visiting.
