Fil de Cassons

Fil de Cassons is a mountain summit in the Glarus Alps standing at 2694 meters with sheer cliffs dropping from its southern face. The peak offers sweeping views across the surrounding Swiss ranges and deep valleys below.

The summit served as a natural landmark for herding communities moving livestock through Alpine pastures. Traditional routes through Val Bargis connected seasonal grazing grounds during summer months.

The mountain forms part of the Glarus thrust geological formation, recognized by UNESCO for its exceptional demonstration of mountain-building processes through plate tectonics.

The summit is accessible from several starting points, with routes from Flims being common choices for most hikers. The climb involves steep terrain and exposed ridge sections that require good physical fitness and solid mountain skills.

The rock faces along the ridge display a striking shift in color from greenish tones to light grey, revealing the distinct geological layers of Alpine mountain formation. This color transition visible to hikers tells the story of how these mountains were built over geological time.
