Park near the southern end of the reservoir, close to a rest area at the Bassin du Flumet, which includes a tree-top adventure course.
(S/E) Head south, pass the facilities and look out for a good track. N.B. Only the post remains of a signpost.
(1) Head up the track, keeping to the right at every junction. Further up, near the houses of Le Coudrai, the route cuts across the track’s hairpin bends. Continue the climb towards Les Fontanettes.
(2) Continue climbing until you reach the edge of a lovely meadow; cross it to reach the village of Montouvrard. Walk up through the village to the start of the iron trail. That will be the subject of another adventure.
(3) Near a small metal cross, head down the path on the right towards the lower part of the village. Continue the descent; the path will cross the road three times before joining a good track.
(4) Ignore the path on the right which leads down to Allevard.
Head slightly uphill, turning left onto the track, and join the road. Follow it for a long way downhill to the hamlet of Colombet and cross through it.
(5) As you leave the hamlet, leave the road and take a path that descends to the left. Join the road further down and follow it to the left to descend to the lake.
(6) Leave the road and head for the eastern shore of the lake. Stay on a tarmac section at first, then on a good track. Towards the southern end of the lake, leave the track.
(7) Head into the meadow and you will soon reach the car park at the rest area (S/E).
