Cycling upthe pass
Climbing the Col de l’Iseran is a challenge that no cycling enthusiast wants to miss. Rising to 2,770 metres, it is the highest mountain road pass in the Alps and one of the most iconic climbs featured in the Tour de France cycle race. From Val d’Isère, the ascent is steady, with a maximum gradient of 7%, offering a rewarding experience for seasoned cyclists and e-bikers alike.
As you climb, the scenery changes from alpine meadows and mountain streams to glaciers and towering peaks, culminating in an exceptional panorama at the summit. Early in the season, the road is sometimes lined with impressive walls of snow, making the ascent even more spectacular. Don’t be surprised if you spot marmots along the way! They are particularly fond of this area, where the first rays of sunshine warm the slopes early in the morning, while the air remains cool and the grass is still plentiful.
Want to take on the challenge without too much effort? E-bikes are available for hire in Val d’Isère, and there are “Accueil Vélo”-certified accommodation solutions offering services tailored to cyclists.

At 2,770 metres above sea level, the Col de l’Iseran is the highest mountain road pass in Europe. Clearing the road of snow is a major annual operation that begins in May and takes several weeks to complete on both sides of the pass. Once reopened, it links the Arc Valley (Maurienne) and the Isère Valley (Tarentaise), between the ski resorts of Bonneval-sur-Arc and Val d’Isère!
In some areas, the snow can reach depths of 8 to 10 metres, not to mention the risk of avalanche caused by such heavy snowfall. As a result, the exact reopening date depends on the progress of the snow-clearing operation and any further snowfall.
