From Champex, take a taxi across the Rhone valley and up a mountain road to drop you close to the Lac de Mauvoisin.
From here, trek to the Cabane de Chanrion.
For the first hour, you walk on a good path just above the lake before heading up to cross the Col de Tsofeiret at 2643m where you make the short descent to the hut for an overnight stay.
