From Refuge Laval
Vallon, located just above the refuge and the chalets of Laval (on the right bank of the Clarée)
From the refuge, cross the Clarée at Pont des Béraudes. Then head towards the slopes you reach that emerge from Lac des Béraudes (these can be a little challenging). Keep to the right of the lake and gradually climbe Col des Béraudes (the last few hundred metres are steep). From the pass, you can make your way back down to Vallée de la Guisane via Alpe du Lauzet.
