Rappenseekopf, Mountain peak in Allgäu Alps, Germany

Rappenseekopf is a 2,469-metre summit in the Allgäu Alps, standing south of the Rappensee lake and east of the Hochrappenkopf, to which it is joined by the broad double saddle of the Hochrappenscharte. A marked path crosses the peak, and it is easily climbed from the route between the Rappenseehütte and the Biberkopf, or from the saddle between the Hochgundspitze and the Rappenseekopf.

The peak received its current name in the late 19th century, inspired by the nearby Rappensee lake. The change from its former name Großsteinschartenspitz marked a shift toward geographic references based on regional features.

The summit cross was placed in 1985 by two Oberstdorf residents in memory of a climbing companion who died on the mountain. The metal cross stands on the 2,469-metre summit, which is reached by a marked path from the Rappenseehütte or from the Hochrappenscharte.

Hikers reach the summit via marked trails starting from Rappenseehütte, the main base for climbers. The route is well-marked but requires sure-footedness on exposed sections.

Rappenseekopf is joined to the neighbouring Hochrappenkopf by the broad double saddle of the Hochrappenscharte. The marked route to the summit also passes the saddle between the Hochgundspitze and the Rappenseekopf, so the peak can be gained from more than one direction.
