Essigberg, Mountain summit in Kassel, Germany.

Essigberg is a mountain near Kassel in Hesse that reaches about 597 meters above sea level. The slopes are crossed by hiking trails that offer different views of the surrounding landscape.

The Essigberg lies on the Diemel-Fulda watershed, and its streams feed either the Diemel via the Warme or the Fulda via the Ahne, Drusel and Bauna. In the mid-1970s the Deutsche Telekom built the 186-metre Fernmeldeturm Habichtswald on the summit at 594.2 metres; it carries Hessischer Rundfunk radio and TV transmitters and is closed to the public.

The summit lies on the Diemel-Fulda watershed: streams flowing west, such as the Laubach, reach the Diemel, while the Ahne, Drusel and Bauna drain east toward the Fulda. The Ahne rises on the Essigberg's slopes. In winter, when snow covers the hill, sledgers gather south of the summit and the transmission tower.

The summit is reached by car via the L3298 between Ehlen and Kassel; an unsigned large hikers' car park lies just west of the road's highest point, near the 186 m telecommunications tower. Buses of the KVG also serve the area. From the car park, views extend west past the Weidelsburg to the Rothaargebirge; a shelter hut stands between car park and tower.

The summit lies on the Diemel-Fulda watershed: streams flowing west, such as the Laubach, reach the Diemel, while the Ahne, Drusel and Bauna flow east to the Fulda. The Ahne also rises on the Essigberg. Maps often give about 595 m, but the hill is at least 597.5 m high.
