Starting from the Refuge de la Lavey, carry on up the Vallon de la Muande and then take the path up towards the Tete des Fétoules.
Starting point: Refuge de la Lavey
Elevation gain: 452 m
Duration: 2 hours
Distance: 10.8 km
After the hut, cross the Muande stream and take the left-hand path signposted Lac des Fétoules. Climb up a series of switchbacks through rockfalls and over grassy slopes up to the lake. The descent is quite steep down to the path leading to the hut. You can also walk back via the Lac des Fétoules on a little-used path along the bottom of the Tête des Fétoules.
The hike is inside the National Park, so no dogs are allowed (even on a lead).
