Schwarzer Grat, Mountain summit in Baden-Württemberg, Germany

Schwarzer Grat is the highest summit of the Adelegg, a range of low mountains in the southeastern corner of Baden-Württemberg, sitting at around 1,118 meters (3,668 feet) above sea level. It stands near the border with Bavaria, on the edge of the northern Alpine Foreland.

The Adelegg range, of which this summit is the highest point, served for centuries as a natural dividing line between different territories, and later became part of the boundary between Baden-Württemberg and Bavaria. Because of its dense forest cover and elevated position, the area remained sparsely settled for a long time.

The summit is topped by the Schwarzer-Grat-Turm, a 28.5-metre wooden observation tower built in 1971; an 1878 viewing pavilion and a 1906 wooden tower preceded it, the latter burning down after a lightning strike in 1967. In summer, drinks and simple food are sold at the tower on Sundays. In very clear weather the view reaches the Tödi, the Jungfrau and the Feldberg in the Black Forest.

Several marked trails lead to the summit, including routes starting from the Wenger Egg Alpe and the Stabkirche Überruh loop. The paths are generally easy to follow from spring through autumn, though they can become muddy after rain.

The Eisenbacher Tobel, a small stream, rises on the southwestern slopes of the summit, making this one of the few source points in the Adelegg area. The word Tobel refers to a narrow, forested ravine typical of this part of southern Germany, and several of these hidden gullies cut through the hillsides around the peak.
