Driving the unpaved road to Col du Mottet in the Vanoise National Park

# Col du Mottet: A High-Alpine Adventure

Tucked away in the Savoie department of France, Col du Mottet sits at a seriously impressive 2,374 meters (7,788 feet) above sea level. This mountain pass—also known as Col de Roche Blanche—is nestled within the stunning Massif de la Vanoise, serving as the dramatic link between Valmorel and the Bellevilles valley. You'll find it at coordinates 45.4299, 6.4266, perched on a ridge that separates two valleys and offering jaw-dropping views toward the Mont Blanc massif.

**What You're Getting Into**

Fair warning: this isn't your typical Sunday drive. The route climbs roughly 10 kilometers (6.21 miles) from Les Avanchers-Valmorel with unforgiving, sustained steepness—some sections hit a brutal 15% gradient. We're talking a narrow, unpaved service road with loose shale and chunky embedded rocks that'll test your nerves. Throw in wet conditions, and the whole thing transforms into a muddy nightmare with virtually zero traction.

This is serious 4x4 territory. You'll need low-range gears, high clearance, and genuine skill to navigate the deep ruts without destroying your undercarriage. Add in the exposed hairpins with stomach-dropping vertical drops and zero safety barriers, and you've got yourself a proper challenge.

**Timing Matters**

Mark your calendar: this route is completely impassable from October through June thanks to heavy snow. Even beyond the weather, there are significant legal and access restrictions to contend with. Plan accordingly, bring your A-game, and respect what this mountain demands.
