From the center of Mizöen village, take the track road to Singuigneret. The climb should take about two hours, without hurrying, up to the Chalet du Fay. You have time to enjoy the views over the Romanche valley, Girose glacier and La Meije.
Go round the Refuge du Fay to join up with the GR 50 which climbs gradually to the Chalets Girardet. Stay on the right-hand track up to "Sur Brèche" (2307 m).
This is the highest point of the ride. You can now enjoy the descent through the pastureland, following signs to the Refuge des Chatons.
The paths descends into a magnificent valley. At the bottom, cross over to the right-hand bank of the stream and continue to the Ruines de l'Alpe and then the Refuge des Chatons.
Cross the track in front of the hut and take the path leading off downhill. This section crosses over a shale wall with a commanding view over the Lac du Chambon. This may sound challenging, but apart from the first two bends, there are no specific technical difficulties. Just make sure you don't fall off.
This path leads back to Singuigneret and then Mizoën, cutting over the track road on several occasions.
