Le tour de Bellecôte par le col de Plan Sery. Boucle 3

First day, from Nancroix (1 450 m ): direction Bauches, then Pramain (1 833 m) then the Tchiaupe pass (2 492 m). Go back down to Champagny and sleep at the refuge du bois de Champagny le haut (1 476 m)

Second day: go up to the Plaisance refuge (2 150 m), then over the Plan Sery pass (2 609 m) and down to the Entre le lac refuge (2 144 m)

Good walkers who are not afraid of going off the beaten track will be able to avoid descending to the bottom of the valley of Champagny le haut. At the level of the Tchiaupe stables (2,303 m), follow the contour line (trail) until the climb to the Frête passage (2,500 m), then the descent into the Froide Fontaine valley, then the ascent to the Golet de la Vallaisonnay (2,796 m). We descend along the Vallaisonnay stream to the refuge: freedom in an extraordinary glacial landscape.

Third day: return via the Plan Sery pass (2,653 m) and via the Entre-le-lac refuge to Rosuel and then Nancroix.

Difficulties: difficult because it is long. Well-marked paths.

Loop that can be done in the other direction!
