Diabla Dziura w Bukowcu, cave in Poland
Diabla Dziura w Bukowcu is a cave in southern Poland extending over 365 meters in length and reaching about 42 meters deep. The site features unusual rock formations made of Carpathian sandstone in varied shapes, with some rising up to 15 meters high.
The cave formed through natural geological processes in the Carpathians and later became a protected area for rare bat species such as the lesser horseshoe bat, which hibernates there. Protected status was established to preserve these valuable natural habitats and the species within them.
Local legends tell of Boruta, a demon said to guard hidden treasures within the caves. These stories shape how visitors experience the rocks and are retold along the trails.
The route to the reserve follows an asphalt road leading to a parking area near an old wooden church where you can safely leave your car. The walking trail is about 1.5 miles (2.5 kilometers) long, well-marked, and suitable for families with children and older visitors, with a full loop taking about 1.5 to 2 hours.
Lesser horseshoe bats overwinter in the cave and have established one of their most important habitats in the region there. The cave remains closed to visitors as a result, though you can sometimes spot the bats in the evening near the parking area as they emerge.
