A Legendary North-Facing Descent in the Le Fornet Sector
Grand Vallon is one of the most well-known off-piste routes in Val d’Isère, particularly in the Le Fornet area, bordering the Vanoise National Park. It offers a 1000-metre descent in a wild, scenic setting, with cold powder preserved by its north-facing orientation.
The route is praised for its diversity of lines, gentle plateaus, and alternating northeast and northwest slopes that allow skiers to adapt to snow conditions. Grand Vallon is a perfect entry point into the world of freeriding at Val d’Isère—for those with solid technique and a sense of independence.

Easy Access from the Signal
To reach the route, you’ll need to ascend the Signal drag lifts, reaching 2920m altitude. These steep and technical lifts tend to deter snowboarders, meaning this zone is mostly skied by skiers only.
From the top, the entry is to the right—dropping into a wide open slope that marks the beginning of the valley. There’s no marked path, but the terrain is intuitive and naturally leads into the descent.

A Wide Valley with Multiple Variants
The Grand Vallon is beloved for the freedom it offers. Once inside the main couloir, you can choose from various lines:
- Stick to the centre for a smooth, consistent ride
- Traverse left for more sustained northwest slopes
- Head right for untracked northeast aspects
The snow remains cold and dry for several days post-storm, especially on the shaded flanks. Depending on snowpack, some sections may feature small cliffs or abrupt slope changes, requiring careful navigation.
For Experienced Skiers Only
While not extremely technical, the Grand Vallon is best suited to advanced skiers who can manage:
- Route-finding in unmarked terrain
- Changing snow conditions depending on elevation and aspect
- Orientation without signage
The descent ends naturally beside the Isère river, just next to the Fornet cable car station at 1920m—ideal for a quick return to the main ski area.
