Vallée Blanche routes from Aiguille du Midi

The Vallée Blanche is one of the most famous off-piste ski descents in the world. Starting from the Aiguille du Midi at 3,842m, the 20km long descent takes you across glacial terrain with incredible views of Mont Blanc and the surrounding Alps.

There isn’t just one Vallée Blanche route. There are several variations, each with its own character. Some are relatively straightforward, others are steep and technical. Below we outline the main options and what to expect on each, plus some preparation tips to make the most of your day.

The Main Vallée Blanche Routes

Classic Vallée Blanche

• Level: Intermediate to advanced skiers with off-piste experience
• Terrain: Broad glacial slopes, moderate gradients
• Why ski it: It’s the most popular line and a great introduction to the Vallée Blanche
• Considerations: Despite being the “easiest,” it’s still glaciated terrain with crevasses

“Vraie” Vallée Blanche

• Level: Advanced skiers
• Terrain: Quieter, more remote, less skier traffic
• Why ski it: A wilder feel with fewer tracks, often better snow if conditions line up
• Considerations: Navigation is more complex; snow can vary a lot throughout the route

Petit Envers du Plan

• Level: Advanced skiers
• Terrain: More variety than the Classic, with some steeper pitches but not as demanding as the Grand Envers
• Why ski it: A good “next step” beyond the Classic route
• Considerations: Crevasses and avalanche exposure still a factor — not a casual alternative

Grand Envers du Plan

• Level: Expert skiers
• Terrain: Steep, narrow couloirs and technical sections with variable snow
• Why ski it: The most impressive and challenging of the Vallée Blanche lines
• Considerations: High avalanche risk and hidden crevasses — requires both ability and solid mountain judgment

Safety and Preparation

Skiing the Vallée Blanche is skiing on a glacier. Conditions change fast, and hazards are always present. A few key points to keep in mind:

• Equipment: Transceiver, shovel, probe, harness, and often crampons
• Timing: Early starts mean better snow and fewer bottlenecks
• Exit: Depending on snow cover, you may ski all the way to Chamonix or finish at Montenvers
• Snowpack matters: Avalanche risk can make the Classic line more dangerous than a steeper variation if conditions are unstable

Most skiers choose to go with a certified IFMGA guide, not only for safety but also because guides know which line will ski best on any given day.

Conclusion

The Vallée Blanche presents many different options. From the mellow Classic to the steep Grand Envers, the route choice depends on your ability, conditions, and what kind of day you want in the mountains.
