Herzogenhorn, Mountain summit in Bernau im Schwarzwald, Germany

Herzogenhorn is a 1415-meter mountain summit near Bernau in the Black Forest of Baden-Württemberg. It is the third highest peak in the Black Forest range and offers diverse routes accessible from the valley below.

Herzogenhorn appears as "des herzogen horne" in a 1328 scroll marking the boundary of the abbey of St. Blaise. Primitive fortifications probably date from around the Thirty Years' War, while the schanzen line is attributed to Margrave Louis William, the "Turkish Louis". In 1904 the Mannheim section of the Black Forest Club built the Mannheim-Ludwigshafen Hut, which burned down on 28 January 1911.

The summit is a long-established gathering place for athletes and hikers from across the region. People use the mountain regularly for training and practicing various winter sports.

Several hiking trails lead from the valley to the summit, ranging from easy to challenging routes. The best time to hike is from May to October, when the weather is stable and the paths are dry.

On clear days, the summit offers views stretching all the way to the Rhine and Lake Constance. During temperature inversions when valleys fill with clouds, the mountain feels like an island floating above a sea of fog.
