Bisse de Grimisuat
The Grimisuat bisse takes its water from the Sionne. In the heights of Grimisuat, this bisse separates into two, both branches ending in Revouire lake. It is fed from two other sources: the Ayent bisse from which it receives 2/7th of its water and the Prabé tunnel (Savièse bisse). At the start of its course, it intersects with the Sion bisse. .

Steps take you up to the path that follows the bisse to above Grimisuat. By road, you can get to the Revouire Lake then the Coop supermarket in the village of Grimisuat. (post bus stop).
