Bisse d'Ayent


Built in 1442, this bisse connects the villages of Ayent and Grimisuat.

Please note: this bisse can also follow on from the Bisse du Ro which leaves Montana or alternatively form a loop with the Bisse de Sion from Anzère.

This is a particularly spectacular bisse which follows, at the outset, an impressive trail perched in the middle of a rock wall. Afterwards, you will discover a reconstruction of the building of the bisse. In the middle of a tunnel which encircles this historical reconstruction, you can reach a viewing platform and observe the wooden canals hanging from a vertical facade.
