_ Start_: From the Col des Montets. There are three car parks.
Waymarkers: Much of this hike follows the GR® Tour du Mont-Blanc and the GRP®
(S/E) Cross the road, follow it in the direction of Chamonix (South-East) for about 300 m, and look out for the path through the forest on the right: this is the GR®Tour du Mont-Blanc.
(1) Follow the wide, well-maintained trail all the way, passing through winding sections, crossing sections and sections with ladders (it's fun), then arrive at the Carrefour de la Tête aux Vents (elevation 2133).
(2) Turn right, via the southern balcony (Les Deviets - La Remuaz - Le Col des Montets). Join the GRP® Tour du Pays du Mont-Blanc and follow it almost horizontally, over a sort of shoulder, for about 1.5 km.
(3) Pay close attention: before a slight rise, spot a very slight trace off to the left (small, unobtrusive cairn). Follow it (North-West then West) for a short while, and don't be fooled a little further on by a trace that goes straight right up the slope.
(4) At around 2170 m altitude, follow the track as it bends North-East, then North, along an almost level path. The track is not easy to follow: a few cairns in places. You soon come to a small pass just above the lake, well hidden in its solitary, unspoilt setting.
(5) Follow the same route back down to the main trail.
(3) Follow it to the left (North) and descend gently to the tarmac road. Cross the road back to the car park (S/E).
