Tips

March 9, 2026

The Höwenegg crater is not one of the dolines typical of the Swabian Alb, but a real volcanic crater. Geologically, it belongs to the Hegau volcanic region. Basalt mining has also shaped the crater's current appearance. You have a wonderful overview from this point.

Hiking

Unlike other volcanic relics and maars in the Swabian Alb, the “Höwenegg” belongs to the Hegau volcanism. The main crater is the largest of a total of 6 eruption sites from which basalt and basalt tuff were mined. The lake that is visible today was created in the former mining area.
The eruption took place 10 million years ago. At that time, a crater lake was formed, which was visited by numerous animals. Fossil discoveries of 13 ancient horses, antelopes and rhinos provide evidence of the subtropical climate of the time. The fossils were excellently preserved in the lake sediment.

Hiking

A very good viewpoint overlooking the crater lake, with a small rest area and information panel. Even though there is a large fence around the crater rim for safety reasons, a good view is still possible.
