Jesberg lies from 210 to 675 m high in the Gilsa river valley east-southeast of the Wüstegarten, which at 675 m above sea level is both the Kellerwald range's and the Schwalm-Eder district's highest peak.

Jesberg consists of the following centres: The Burg Jesberg, a castle built by the noble family of Linsingen in 1241, was later sold to the Archbishopric of Mainz, and along with Naumburg and Fritzlar was one of the Archbishops' main bases in the struggle against the Landgraves of Hesse.

It can still be seen, along with its centrepiece, the Prinzessingarten-Eiche, a big oaktree, although nowadays, little of the actual garden is still preserved.

The small Baroque stately home was built by Maximilian von Hessen, Landgrave Karl von Hessen-Kassel's son — whose four daughters also inspired the Princess's Garden — on the lands near the Treisbach (brook) in the early 18th century.

The community has a forest lore path, a campsite, a leisure centre, two barbecue areas with barbecue huts, a heated outdoor swimming pool, a sporting ground, a wading pool, five children's playgrounds, three tennis courts, a soccer pitch, two minigolf courses and skittle alleys.
