Summer In summer, Les 2 Alpes becomes a popular venue for downhill and freeride mountain biking, with access to the glacier via the Jandri Express gondola lift, with a yearly event named "Mountain Of Hell". This opens up a vertical mile of trails down to the resort and an even bigger drop to the Barrage du Chambon.

Some mountain bikers take the 15 km unpaved road, which leads from Les Deux Alpes all the way up to the ski resort, thereby being the highest mountain road in the Alps.
