Blauer Stein

Blauer Stein is a volcanic cone in the Hegau region with dark basalt rock formations that rise distinctly from the surrounding landscape. The mountain displays the geological characteristics typical of this southwestern German area.

The formation was created through volcanic activity millions of years ago and is part of a series of volcanic cones that define the Hegau landscape. This rock formation documents a period of ancient magmatic activity in the region.

The mountain serves as a natural monument where residents and visitors gather to experience the geological heritage of southern Baden-Württemberg.

Hiking trails lead up the mountain and allow visitors to choose different routes based on ability and preference. The walk offers good viewpoints along the way and chances to observe the basalt formations from various angles.

The mountain is part of a group of over 40 volcanic cones made primarily of basalt that pepper the Hegau landscape like an island chain. This geological setting makes the region a rare example of Tertiary volcanic activity in central Europe.
