Hesselberg, Mountain summit in Hesse, Germany.

Hesselberg is a wooded hill in the Taunus, in the Butzbach forest, reaching about 518 m above sea level. Its summit rises 850 m east-southeast of the village church of Bodenrod, a district of Butzbach, and a transmission tower stands slightly southwest of the top. It is the highest point in the northeastern part of the Eastern Hintertaunus.

The name originated from Öselberg, meaning bleak mountain, and later became Eselsberg, reflecting linguistic shifts across centuries. This transformation shows how the German language evolved in this region.

The hill sits on the watershed between the Lahn and Main rivers: the Solmsbach rises to the north near Espa, the Fauerbach to the east, and the Krebsbach, which feeds the Forbach, to the southeast. The European long-distance trail E3 crosses the mountain, and the summit stands 850 m east-southeast of Bodenrod's village church, with a transmission tower just southwest of it.

The summit can be reached from several starting points with marked paths that make navigation straightforward. Information centers in nearby towns provide hiking maps and guidance for route planning.

The summit stands on the watershed between the Lahn and Main rivers: the Solmsbach rises to the north near Espa, while the Krebsbach, a tributary of the Forbach, rises to the southeast and reaches the Main through the Usa and Wetter. A transmission tower stands just southwest of the 518-metre summit, and the European long-distance trail E3 crosses the hill.
