Bollerberg, Mountain summit in Hallenberg, North Rhine-Westphalia, Germany

Bollerberg is a mountain in the Rothaargebirge range that rises to approximately 758 meters, with dense forests covering its slopes. Several marked hiking trails cross the mountain and connect various routes through this ridge area.

A 15-metre wooden observation tower was built on the summit in 1936 and stood until 1945. The present Bollerbergturm, also 15 metres tall, was erected in 1976/1977; 84 steps lead to its top viewing platform. The summit clearing with the tower and a telecommunications mast lies in the Hesborner Wald forest.

The name Bollerberg is used for the wooded summit above Hesborn, where a 15 m wooden observation tower stood from 1936 to 1945. Today's steel tower, built in 1976/77, has five viewing platforms reached by 84 steps. The clearing around the towers is the goal of walks from Hesborn and Züschen.

The summit is reached on foot; the Bollerbergturm stands on a clearing in the Hesborn forest, about 1.5 km northwest of Hesborn. Its top platform is reached by 84 steps. The tower is 15 m high and offers orientation toward the Ziegenhelle massif to the southwest and the Medebacher Bucht to the east.

The 1976/77 steel tower replaced a 15 m wooden observation tower built in 1936 and used until 1945. From its top platform, reached by 84 steps, the 816 m Ziegenhelle massif stands out to the southwest, under 7 km away.
