Bolberg, Mountain summit in Baden-Württemberg, Germany.

Bolberg is a mountain in the Swabian Jura whose main summit, at 881 m above sea level, is the highest point in the Reutlingen district. It lies at the northern edge of the Swabian Alb, 2 km north of Willmandingen and 1.5 km southeast of Öschingen. A subordinate, freely accessible rise carries the Willmandinger Albvereinshütte, a shelter hut with a fire pit.

Bolberg formed during the Jurassic period millions of years ago through deposits of marine sediment in an ancient sea. This geological history continues to shape the mountain's composition and the surrounding landscape of the Swabian Jura.

The Willmandinger Albverein maintains a shelter hut with a fire pit on a lower, freely accessible rise of the Bolberg, not on the 881 m main summit. The town of Sonnenbühl runs a 14 km cross-country ski trail, the Bolberg-Loipe, around the mountain, mostly over open terrain.

The summit is reached on foot; the nearest villages are Öschingen 1.5 km northwest, Willmandingen 2 km south and Talheim 2 km southwest. The Willmandinger Albvereinshütte stands on a lower, freely accessible rise with a fire pit, and an orientation board at the viewpoint names the peaks and towns in the distance. The 14 km Bolberg cross-country ski trail, maintained by Sonnenbühl, circles the mountain mostly over open ground.

The main summit, at 881 metres, is the highest point in Reutlingen district. A short distance away, on a lower knoll that is freely accessible, stands the Willmandinger Albverein hut with a fireplace; in clear weather the view reaches the Alps to the south and Stuttgart's television tower to the north, and an orientation board names the peaks and villages in sight.
