The high point around Megève, Saint-Gervais-les-Bains, and Les Contamines-Monjoie. Started at Le Bettex, where I parked.
The first stretch runs along the ski slopes, not the most interesting part. It picks up once the actual ascent starts, medium difficulty from there, and genuinely exposed in a couple of spots. Not one for anyone afraid of heights.
The summit view makes up for it: the Beaufortain on one side, the whole Mont Blanc range on the other.
