Birkelhöhle

Birkelhöhle is a natural cave in Heidenheim an der Brenz that opens into Jurassic limestone rock with a distinctive keyhole-shaped cross-section. The entrance sits at about 580 meters elevation and provides access to a cave passage that displays the geological layers and formations typical of the Swabian Alb region.

The cave formed during the Upper Jurassic period when limestone sediments accumulated in the region. This geological development shaped the landscape of the Swabian Alb over millions of years.

The cave belongs to the Stuttgart administrative district's geotope collection and serves as a research site for speleologists studying cave formations.

Bring your own flashlight since the cave has no artificial lighting and the ground can be slippery in places. Wear sturdy shoes with good grip to safely navigate the uneven and damp surfaces inside.

The cave connects to hiking trails that lead past historic iron ore mining sites in the surrounding area. This connection reveals how geology and mining activity shaped the region's past.
