Roche de Mio

The road to the summit, located within the Vanoise Massif, is gravel, rocky, tippy and bumpy at times. The road is impassable from October to June. Great trail for experienced wheelers. Avoid driving in this area if unpaved mountain roads aren't your strong point. 4x4 required. Stay away if you're scared of heights. Expect a trail pretty steep. It’s one of the highest roads of France. Wet conditions may make for tough driving along the muddy road, lying in the northern part of the Vanoise National Park.
