Teufelstein, Mountain summit in Fulda, Germany

Teufelstein is a 729.4 m high mountain in the Milseburg Kuppenrhön near Poppenhausen in the Hessian Rhön. At its summit lies a 200 m long phonolite intrusion with inclusions of mica schist in the local Buntsandstein; nearby phonolite blocks form partly five- to six-sided columns. The rock formation is protected as a natural monument and gave the mountain its name.

The Teufelstein is a 200-metre-long phonolite intrusion in the local Buntsandstein, with inclusions of glimmerschiefer; phonolite blocks nearby form five- to six-sided columns. The rock formation at the summit is a designated natural monument and gave the mountain its name. A legend about the devil, linked to the nearby Gangolfskapelle, likely contributed to the naming.

The name comes from a local legend about a resident who won a contest against the devil, and the mountain was named after this tale. Visitors often see the rock formations as a natural sculpture that marks a special place in the landscape.

The summit is reachable via hiking trails from the parking area along Federal Road 458 through the Hessian Rhön Nature Park. Sturdy footwear and plenty of water are advisable since the route crosses rocky terrain.

The summit rocks are phonolite, a volcanic rock that here forms five- and six-sided columns; loose blocks of it lie around the top. The 200-metre-long phonolite intrusion carries inclusions of glimmer schist in the local sandstone. The pass of Grabenhöfchen between Teufelstein and Weiherberg, at 685 m, marks the watershed between the Fulda and Werra.
