It is a fascinating little cave to explore, long enough to be visited with a lantern. The cave, which is hidden in the side of the Bajna Guard-Hill, can be reached from any direction by following the green triangle sign from Bajna, which is a pleasant walk in the form of a circular path. A small path branching off from the signpost also has a sign saying “Cave” to help you find it. If you want to reach it by the shortest possible route, start from Epöl!
