Outdoor Recreation - Caserma Ederle Bldg. 249 Google Map

The Postojna cave system covers over 21 kilometers and features amazing formations made from constantly dripping water. While some tunnels are flooded and unable to be entered without special equipment, we will be touring some other great caves in the system and taking in the beautiful sights. It's cold in these underground caves, so bring a warm jacket!

For a turn aboveground, we will visit Predjama Castle, an impregnable fortress built out of the mountain itself. This centuries old castle is full of history and the perfect way to finish off your day in Slovenia.
