After passing Le Bourg d'Arud, park at the first hairpin bend (D530). The path starts just above on the right as you go uphill (you can also start from Alleau by taking the well-marked path that climbs up the left bank of the Ruisseau de la Pisse).
(S/E) The path immediately begins to climb through the forest to Laffreyete.
(1) From Laffreyete, continue towards Le Cerisier. In the forest, a few windows open onto the village of Venosc, which is part of Les Deux Alpes. You will begin to see the first houses of this ski resort on the ridge above the village.
After the bridge, you will find yourself at Le Cerisier.
(2) At Le Cerisier, you can fill up your water bottles and there is a picnic table. Continue along the path towards Lac de La Muzelle (note that you will soon enter the Parc des Écrins).
After leaving the forest, the trail follows the stream and offers beautiful views of several waterfalls.
(3) The trail then crosses the Ruisseau de la Pisse and, from there, the climb becomes steeper with steps. Looking back, you will have a beautiful view of the Deux Alpes resort and the La Muzelle glacier will soon appear before you reach the lake and the refuge.
(4) You have now arrived at the refuge and Lac de La Muzelle, which you can walk around to reach Lac de la Muzelle.
(5) The return to the car park (S/E) is via the same route as the outward journey.
