Fil de Cassons (also known as Cassonsgrat) is a mountain in the Glarus Alps, located near Flims in the canton of Graubünden, Switzerland.

For hikers aiming for more than a walk, several routes reach the high plateau and the very wide ridge, among them a historic Via Ferrata called Pinut.

One hiking route uses the ascent via Val Bargis and Scala Mola, the path that the cows are being sent up to graze in summer.

If you stay at the base of the valley of Bargis, you will hike on a path leading more or less around Fil de Cassons from east to northwest before reaching its top.

[2] Being a ridge, there is very often hardly snow, allowing walks even in winter along at least one mile on Fil de Cassons.
