The Island in the Sun — home of the longest black run in the Alps.
Computed from mapped terrain data — no editorial opinion, no pay-to-rank. How the score works
Alpe d'Huez sits on a broad, south-facing shelf high above the Romanche valley, soaking up so much light that the French call it L'Île au Soleil — the Island in the Sun. In summer its 21 hairpin bends are cycling's most famous climb, a Tour de France amphitheatre; in winter the same sun pours onto one of France's biggest linked ski areas, rising from village orchards to the 3,330 m summit of Pic Blanc.
From that summit launches the run that made the resort's name: La Sarenne, around 16 km of black-rated descent through a wild, road-less gorge — usually cited as the longest black run in the world. But the area's real strength is its breadth: enormous sunny beginner plateaus right above town, endless mid-mountain cruising, and a serious dark side too, with the steep Tunnel run and big off-piste faces that stay cold on the shaded aspects.
It's a resort where a family, a first-timer and a vertical-obsessed expert can share a lift up and each have their best day of the season.
Around 16 km from Pic Blanc through a remote gorge — the longest black run in the Alps, more scenic marathon than fright-fest after the steep top pitch.
Through a rock tunnel under the Pic Blanc ridge and out onto a genuinely steep, often bumped-out wall — the local test piece.
Quieter reds and blues facing the main resort, with the best views back across the whole sun-drenched bowl.
Every run measured from elevation-aware map geometry: true length, vertical drop, average gradient and a 0–10 slope score that rewards long, sustained descents.
