Col de l’Iseran, Europe’s highest paved pass, is a must-visit for col-hunters. It’s only accessible for a few months each year and can become quite crowded during those months.

Starting from the Tarentaise Valley, it’s not advisable to begin the ride from Bourg-Saint-Maurice. The route to Tignes and Val d’Isere is frequently used by fast-moving cars and features dark tunnels, making it less safe for riders. A better starting point is Val d’Isere, roughly 15 kilometers from the summit. This section offers a rewarding climb with breathtaking views of Lac du Chevril and the towering 3,656-meter Grand Motte.

On the other side, the climb from the Maurienne Valley is more challenging. Riders face over 1,400 meters of elevation gain starting from the bustling resort of Lanslebourg-Mont-Cenis.
