Grünhorn, Mountain summit in Vorarlberg, Austria

Grünhorn is a 2,039-metre double-peaked grass mountain in the Allgäu Alps of Vorarlberg, part of the Baader mountain rim. Its slopes are built of flysch rock and drop away steeply only on the northeast side. The broad summit rises above the Steinmandl to the north and the Hochstarzel to the south, with Baad in the Kleinwalsertal and Schoppernau as the nearest villages.

The Grünhorn belongs to the Baader Bergumrahmung, a ring of peaks around Baad whose Flysch rock supports an unusually rich flora. The double-summit grass mountain drops steeply only on its northeast side, above the Steinmandl to the north and the Hochstarzel to the south. Baad in the Kleinwalsertal lies southeast and Schoppernau southwest; the Inchen peak is 2.3 km away.

The name Grünhorn, "green horn", refers to the grassy, double-peaked summit that stands out against the surrounding Flysch rock. The Baader mountain rim around it is known for its very rich flora, which hikers notice on the eastern flank and the broad ridges.

The climb from Mittelberg takes about 5 hours and covers a height gain of around 500 meters on a well-marked trail. The terrain is best walked in proper hiking boots and water should be taken in sufficient quantity.

The Grünhorn has two grassy summits and drops away only on its northeast side, where steep walls fall toward the Steinmandl. Its north ridge route from the Steinmandl crosses a broad ridge, then some gendarmes (grade I) and an exposed but secured steep section before the fore-summit; the main summit lies beyond a saddle. The climb needs sure footing and alpine experience and takes about 45 minutes from the Steinmandl.
