Horst, Wooded hill summit in the Spessart, Hesse, Germany

Horst is a 539.6 m high, densely spruce-forested hill in the Hessian Spessart, about four kilometres south-east of Bad Orb. It is the highest point in the Bad Orb municipal area and in the Orber Reisig ridge, yet rises only slightly above its surroundings. Ferns and foxgloves grow near the summit, where two identical antenna masts and a sign reading "Horst, 540 m" mark the top.

The term Horst was coined in 1883 by geologist Eduard Suess to describe a raised fault block bounded by fractures in the earth. This geological concept helped explain the formation of mountain ranges including the Spessart.

The hill lies in the Orber Reisig, the ridge between Bad Orb and the Jossgrund, and is reached on waymarked routes of the Spessartbund, including paths from Bad Orb through the Bremer Grund or the Kurzes Tal and from Villbach past the Bad Orb-Jossgrund golf course. Near the summit stands a sign reading "Horst, 540 m".

The trails are accessible throughout the year, with spring and autumn offering the most pleasant conditions for visiting. Sturdy footwear is advisable due to the steep slopes and uneven terrain.

The summit is marked by two identical antenna installations and a sign reading "Horst, 540 m"; without them the low, rounded hilltop would be hard to identify. Only a clearing just south of the top allows a partial view into the ridges of the Bavarian Spessart.
