Planggenstock, Mountain summit in Glarus, Switzerland

Planggenstock is a mountain summit in the Swiss canton of Glarus, standing at about 1675 meters in elevation. It features steep flanks and a pronounced ridge that extends toward the neighboring Hirzli peak.

The Planggenstock is the northernmost summit in the canton of Glarus, rising about 1,200 metres above the Linthebene plain near Bilten. Its northern slope belonged to the former municipality of Bilten, which joined the unified municipality of Glarus Nord in 2010. The Niederurnen-Morgenholz cable car, built in 1965 mainly for the schoolchildren of farms in the Niederurnen valley, now also serves hikers heading for the summit.

The Niederurnen-Morgenholz cable car, built in 1965 mainly for the schoolchildren of farms in the Niederurnertal, still carries hikers up to Morgenholz. From there, paths lead on to the Planggenstock or the Hirzli to the east. The summit and the ridge toward the Hirzli are made of Nagelfluh rock, the same conglomerate that continues on the Speer across the Linth plain.

The Niederurnen-Morgenholz cable car, built in 1965 mainly for the farm children of the Niederurnertal, runs up to Morgenholz and shortens the approach for hikers heading to the Planggenstock or the Hirzli to its east. From Morgenholz the route continues on foot; the summit and the ridge toward the Hirzli are Nagelfluh rock, which can be slippery when wet.
