Portes du Soleil: the name stands for cross-border, unbounded skiing fun. 14 skiing areas - 8 of them in France and 6 in Switzerland - with over 200 lifts and cable-/railways combine to make the largest single skiing area in the world. In summer things are much quieter here, but even in the warmer months there is spectacular sport. Word has spread in the biking community about the massive bike park with its many downhill slopes and tricky tracks, and it is becoming very popular. Nevertheless, there is room for walkers too.
