The Bad Hole cave was formed in the floe of the limestone and dolomite of the Branisko mountain range. The surroundings was originaly covered with thick beech and fir forests. In the past they were cut and changed into meadows and terrace fields. For several centuries they provided food for the local inhabitants. At present most of these places have been planted with pine trees.
Several rare and protected plants grow here, such as lilies or asters. Local woods are full of roebuck, boars, and many kinds of birds. The cave is the home for about 250 bats of 12 species.
