The downstream valley from Courchevel Moriond.
A short hike on a mountain bike. Very approachable. Mounted by the tracks by a route half road half road. The descent is done on the other side where you switch to a wilder environment on a small path of about 2kms with short very steep passages for a few tens of meters, feet on the ground for the less daredevil, but nothing insurmountable or too committed. The environment on this side is truly extraordinary. You will surely meet our friends the marmots and other mountain inhabitants.
Possibility of catering at the refuge of the grand plan and why not an overnight stay. The rest of the descent is done by a wider path and partly passable but in a natural setting of extreme beauty. To discover and rediscover.
