From Dzovenno, take the small road on the left towards Berrié (signposted No. 1 then No. 2). At Berrié, on the right, take trail No. 3 which leads to the Tsa mountain pasture. Trail No. 3 continues behind the cowshed.
The descent to Grand Chamin can be tricky in bad weather. The trail then continues on the other side of the stream (small bridge). At the intersection, take the trail on the left, which stays at altitude and under the trees. Join the road just before the tunnel and continue to the dam. Follow the lake to the Prarayer refuge.
