Ammergauer Hochplatte, Mountain summit in Ammergauer Alps, Germany.

Ammergauer Hochplatte is a mountain summit in the Ammergauer Alps in Bavaria, sitting at around 6,830 feet (2,082 meters) above sea level, with a clear west-to-east ridge defining its shape. The terrain is rocky and steep on most sides, though marked trails and fixed rope sections guide hikers along the standard routes.

The sources record no German Alpine Club first ascent; the documented routes are the normal path from the Kenzenhütte (1294 m) via the Scheinbergalpe and the east side, and the harder T4 route over the Fensterl and the west ridge with UIAA I climbing and fixed rope sections. The standard ascent is usually given as about two and a half hours but takes at least three in practice.

The name Ammergauer Hochplatte distinguishes this peak from other Hochplatte mountains in the Northern Limestone Alps. Its two summits lie about 200 metres apart; the lower eastern one at 2079 metres carries a summit cross. The mountain lies within the Ammergebirge nature reserve, and the karst terrain south of the ridge drops toward the Ammersattel.

The easiest route starts at the Kenzenhütte (1294 m) and leads via the Scheinbergalpe, then through karst terrain up the east side; allow at least three hours rather than the two and a half hours given in guidebooks. A harder alternative (T4) goes over the Fensterl, the saddle between Krähe and Hochplatte, and along the west ridge, with fixed ropes at the difficult sections.

A natural gap in the ridge known as the Fensterl, meaning 'little window' in Bavarian dialect, frames views to both the north and south sides of the mountains at once. Hikers often stop here longer than anywhere else on the route, drawn by the contrast between the two landscapes visible through the same opening.
