Aiguille Croche: Driving the 18 Hairpins of the Beaufortain Ridge
At an elevation of 2,398m (7,867ft) above sea level, Aiguille Croche is a high mountain peak on the border of Savoie and Haute-Savoie. The road to the summit is a technical ski-lift service track located within the Beaufortain Massif, famous for its narrow ridges and total exposure.

How is the road to Aiguille Croche?
The 11.6 km climb starts from Les Contamines-Montjoie. As seen on the ground, the track is a primitive service road with a surface made of loose slate and crushed mountain rock. It is a bumpy ride where traction is hard to maintain, especially on the 18 sharp hairpin turns. The road is extremely narrow and follows the crest of the mountain with zero safety barriers. One side of the track often drops off steeply into the valley, making it a high-stress drive for anyone not used to unprotected shelf roads.
Can you drive to the summit in winter?
No. The road becomes part of the ski slopes and is completely buried under snow for most of the year. Even in the summer, the track is only passable during a short window. Wet conditions turn the slate dust into a slick paste, making the steep ramps dangerous even for 4x4 vehicles. The climb ends about 40 meters below the actual peak, near the top station of the ski lift.
What are the main hazards on the Aiguille Croche track?
The primary hazards are the unstable surface and the extreme exposure. The loose slate tends to shift under the weight of the vehicle, and the 18 hairpins are so tight that long-wheelbase vehicles may need to perform multi-point turns on the edge of the cliff. There is no room for error and almost no passing space. At 2,398 meters, your engine will struggle with the thin air; using low-range gears is mandatory to control the vehicle during the steep descent and avoid overheating the brakes.
Logistics and Equipment
There are no services, fuel, or shelter on the ridge. You must be fully self-sufficient before leaving the valley. A high-clearance 4x4 is a requirement to clear the rocky steps and deep ruts. Mobile signal is unreliable once you are behind the main massif. Due to the risk of rockslides, avoid this route after heavy rain, as the Beaufortain shale is known for being unstable when saturated.
