Does anyone know if the Postojna Caves and Predjama Castle are included on this tour? It's just outside Ljubljana, and was going to make a side trip, but worried it may be someplace we stop on the tour, while on our way to Lake Bled, but just isn't mentioned by name on the itinerary? kc
No they aren't included in the tour (I was on the tour this past April)
No, they are not on the tour, but it is very easy to do these in advance of your tour. I used Slovenian Explorer and was quite pleased. They picked up and dropped off at the hotel. Tour guide/driver and 4 other passengers in the van.
