The departure point is the lodge de l'Eau Blanche, where Sylvie and Bruno are charming hosts.
(S/E) Go down the D210 road that we arrived on.
(1) At the first bend, take the track on the left, which soon becomes a well-marked path. It crosses the Combe de Coudaye and continues to a crossroads at an altitude of 1702 metres after crossing several streams.
(2) Leave the path on the right that leads to Col d'Ornon and Col de Corbière and turn left towards Croix du Carrelet and Col de La Selle. The well-marked path leads to a metal shelter at around 1,800 metres.
(3) The trail starts to the right of the shelter but is less well marked and requires a little attention. Overall, it follows the ridge overlooking the Combe du Grand Renaud.
(4) At around 1930m, the trail changes direction, heading due east. It is well marked again and easy to follow. Arrive at Clot de la Selle (sign).
(5) Continue straight ahead towards Croix de Carrelet for 1.4 km. Reach the Croix de Garde ridge at an altitude of 2,112 metres.
(6) Continue straight ahead and you will soon reach Croix du Carrelet.
(7) Take the newly marked trail along the edge of the plantation to join a trail coming from Villard-Notre-Dame.
(8) Turn left to pass through Les Maisons du Loup and continue straight on towards the Col du Solude.
(9) At the pass, turn left to reach the lodge through the village streets (S/E).

I recommend it and would gladly do it again when the opportunity arises
