Hochrappenkopf, Mountain summit at 2425 meters in Steeg, Austria and Oberstdorf, Germany.

Hochrappenkopf is a double summit in the Allgäu Alps, reaching 2425 m above sea level on the German side and 2424 m on the Austrian side, on the border between Bavaria and Austria. It lies south-southwest of the Rappensee, with the Rappenseekopf (2469 m) directly east and the Biberkopf (2599 m) to the southwest. A ridge runs north to the Kleiner Rappenkopf (2276 m).

Hochrappenkopf is a double summit, 2425 m and 2424 m high, in the Allgäu Alps on the Austrian-German border. The sources record no historical events, summit cross or centuries-old border role for the peak; its documented history is one of mountaineering: a marked path from the Rappensee Hut to Biberkopf allows an easy ascent, while the northwest ridge is a rarely climbed grade III+ route on partly brittle rock.

The normal route leaves the marked trail between the Rappensee Hut and the Biberkopf, so most climbers reach the double summit in passing. The northwest ridge, a grade III+ climb on partly brittle rock, is rarely attempted. The Rappenseekopf (2469 m) lies directly east, the Kleiner Rappenkopf (2276 m) to the north.

The hike from either Steeg or Oberstdorf takes several hours depending on the route chosen. Proper mountain gear, sturdy boots, and favorable weather conditions are necessary for a safe climb.

Hochrappenkopf is a double summit: the sources give 2425 m and 2424 m for its two tops. The northwest ridge is a grade III+ climb on partly brittle rock and is very rarely ascended; most hikers reach the peak by the marked path from the Rappensee Hut route toward the Biberkopf.
