Park in the car park by the Chalet de Caron.
(S/E) Head south, passing the Chalet de Caron on your left, followed by the joint cable car station for the Cairn and Caron cable cars.
(1) Pass under the Moutière chairlift line and head up a stony track which runs roughly parallel to the Caron cable car line. This will take you to the upper station of the Caron cable car (which is also the lower station of the Cime de Caron cable car).
(2) Pass beneath the cable car line and continue eastwards along a wide dirt track. Go round the start of the Grand Fond Funitel on the left and reach the Refuge de la Moutière.
(3) Then turn left to quickly reach the lakeside.
(4) There are two options for returning to the starting car park (S/E):
- On foot, following the same route in the opposite direction.
- Take the Moutière chairlift, whose top station is situated between the lake and the refuge.
