Hochkelberg, Mountain summit in High Eifel, Germany.

Hochkelberg is a mountain summit in the High Eifel region, rising to 675 meters and covered with dense beech forests on its slopes. A transmission tower stands near the peak, visible from various points around the mountain.

The mountain formed as a stratovolcano, with its basaltic core pushed to the surface over millions of years by geological processes. This volcanic past shaped the landscape that exists in the High Eifel today.

Roman building remains have been found on the slopes of the Hochkelberg, which is covered today with dense, species-rich beech woods. The mountain and the Mosbrucher Weiher at its southern foot lie within the Hochkelberg nature reserve, established to protect this forest and the crater lake.

The mountain rises between Köttelbach, Bereborn, Kolverath, Sassen and Mosbruch, and the Mosbrucher Weiher lies at its southern foot east of Mosbruch. Mountain and lake sit within the Hochkelberg mit Mosbrucher Weiher nature reserve. The southern summit carries a transmission tower, so the wooded slopes are best followed on marked paths.

The Mosbrucher Weiher at the southern foot is a maar, a crater lake formed by an explosion when the Hochkelberg volcano was active. The mountain and the lake together form the Hochkelberg mit Mosbrucher Weiher nature reserve.
