The Glärnisch is a mountain massif of the Schwyz Alps, overlooking the valley of the Linth in the canton of Glarus, Switzerland. It consists of several summits, of which the highest, the Bächistock, is 2,915 metres (9,564 ft) above sea level. Until 2013, the highest point was considered to be an unnamed point with a summit cross at 2,914 m (9,560 ft) (until 2013: 2,915 metres). The other main summits are the Vrenelisgärtli (lit. 'Little Verena's Little Garden' at 2,904 m [9,528 ft]) and the Ruchen (2,901 m [9,518 ft]).
The massif of the Glärnisch consists of two ridges of either side of the firn named Glärnischfirn, culminating at the Ruchen to the west, rising more than 2,000 metres (6,600 ft) above the Klöntalersee, and at the Bächistock to the southwest. The Vrenelisgärtli is the closest peak to Schwanden. East of the Glärnisch is located the lower Vorder Glärnisch.
