It is surrounded by several other mountains and hills that range in height between 550 and 650 m above mean sea level.

From the roughly 20 m high observation tower, which stands next to the inn on the summit of the Großer Knollen, there is a view not only over the mountain peaks of the Harz, but also southwards to the Rotenberg and Eichsfeld.

Numerous walking trails radiate from the summit, including paths to Bad Lauterberg, Herzberg, Scharzfeld, Sieber and Sankt Andreasberg.

The roughly 12 km long path to Sankt Andreasberg runs over a crest over 600 m high with many wonderful views.

Today the lower flanks of the Großer Knollen are mainly covered by beech, but some spruce also grows in higher areas.
