Mountain Alpine peak in Canton Uri offering mountain trails.
A mountain in Canton Uri, Piz Badus offers alpine hiking routes and summer trails; walkers come for high-mountain scenery and ridge walks in Switzerland’s alpine terrain.
Piz Badus, also called Tomül in Romansh, is a mountain in the Glarus Alps of central Switzerland with an elevation of approximately 2,928 metres. It sits on high ground that separates alpine valleys and is a known objective for hikers and mountaineers.
Routes to the summit traverse alpine pastures and rocky paths; the mountain provides panoramic views across nearby ranges and into adjoining cantons. The area around the summit includes high-mountain lakes and typical alpine terrain.
