Hohenstoffeln, Volcanic mountain in Hegau region, Germany

Hohenstoffeln is a double-peaked volcanic mountain in the Hegau region between Binningen and Weiterdingen. Its southern summit reaches 832 m above sea level, while the northern summit, formerly the middle one, is 841.8 m high. The northern summit bears a cross and a shelter hut with a summit register. Thick vertical basalt columns are visible at the top.

Hohenstoffeln is a volcanic double peak in the Hegau, formed from tuff layers and basalt columns. Basalt quarrying began at the north summit in the early 20th century; by 1914 a cableway carried up to 1,000 tonnes daily to Mühlhausen. After protests led by poet Ludwig Finckh, quarrying stopped in 1939, and the summit became a nature reserve in 1941.

A large cross stands on the summit and can be seen from far across the surrounding plain, making the mountain a reference point for people in the region. Walkers often head up specifically to reach that spot and look out over the Hegau landscape and Lake Constance.

The mountain is accessible via marked hiking trails that approach the summit from several directions. Sturdy footwear is a good idea, as some sections are steep and can be slippery when wet.

Quarrying in the 19th century removed so much rock from one of the two peaks that it is now noticeably lower than it was before work began. The difference in height between the two peaks is therefore not a natural feature but the result of human activity.
