Chalets de Chailloux.
The route starts at the ice rink in Les Houches, crosses the river and railway line on the road before following a forest trail that leads to Le Bettey and Plan de la Cry.
The second half of the climb is on a forest and gravel track.
At Chalets de Chailloux there is a buvette and the views are amazing.
It is well worth the effort.
This leg is classified Black due to the length of the climb, the steepness of the initial section and the technical and steep nature of many other passages, you will need a helping push.
If you are self-driving or have a support vehicle we strongly recommend you start the hike at the carpark near Le Bettey above Coupeau.
This will mean you avoid either a long road section or a steep initial climb on a technical trail, plus shortening the day by 1.5 hours.
