We are experienced cavers so we went on the 4 hour trip in inflatable boats, we had to paddle about 3 kilometres and carry the heavy boats over roof falls or sections where the water was too shallow..... more »
Very nice guide trough the cave. With a very smart guide.
Really great exploring experience! Ask for the paddling Tour. It takes 4-6 hours and starts at 5 PM. Make a Phone call first (they speak English, Italiano and german) if a Tour is sheduled and a free spot is available. For standard Tour follow the Website.
