The trip from Novo Mesto to Izola is only a couple of hours by car and there are a number of things that you can check out on the way. We stopped off at Otocec Castle for a quick look. It is quite pretty and has been converted to a hotel and restaurant. It would be a lovely venue for a special event.
From here we travelled down the highway to Predjama Castle and the caves below. We completely underestimated the time required to see the castle, the caves below and the other caves (Postojna ) which are about 9km away. You really could do with a whole day for the 3 sites if you are into caves. You can buy a multi ticket which gives access to all 3 sites and if interested a couple of others.
The castle is really stunning even if you don’t go inside as it is set into the rock face. You are able to buy tickets to go inside and there are audio guides in a large number of languages.
The caves while not linked to the castle are directly underneath. If you are happy inside caves, not afraid of heights and are okay in the dark with a headlamp, it is a great trip.
The cave tour was really interesting and worth a visit. We didn’t make it to the Postonja caves but they are apparently really worth a visit.
