Karlshöhle and Bärenhöhle

Bear's Cave (German: Bärenhöhle) is a tourist cave in Sonnenbühl, Germany. It is named after the numerous cave bear skeletons found there, that likely inhabited the site 20,000 years ago. With 80,000 visitors annually, it is the most visited show cave in Swabian Jura. Bear's Cave was formed in limestone of the White Jurassic, and provided shelter for various types of prehistoric animals. The caves have also been home to a theme park, Dreamland, since 1974. The cave is made up of two parts, the Karlshöhle, discovered in 1834, and the Bärenhöhle, discovered in 1949. The first part of the cave was initially vandalised and pillaged by visitors upon its discovery, and was only reopened to the public upon the discovery of the second cave.
