The Großes Teufelshorn (2,363 m (AA)) is the higher and more northerly summit of the two Teufelshörner and the highest peak in the Hagen Mountains, a part of the Berchtesgaden Alps.

The two Teufelshörner rise up between the basin of the Bavarian Röth and the Austrian Blühnbach Valley [bar; de], both are extremely remote.

The Teufelshörner are joined by a rocky knife-edge that marks the border between the state of Salzburg and the district of Berchtesgadener Land in Bavaria.

A climbing route runs along the challenging rocky ridge (UIAA grade II), which is neither marked nor secured and should therefore only be attempted by experienced climbers.

The final section involves several easy climbing passages, but sure-footedness and a head for heights are absolutely necessary.Using the normal route summit of the Teufelshorn may be reached in 6 to 7 hours from the Obersee.
