One of the world's biggest ski areas, Portes du Soleil is a Franco-Swiss region comprising 12 ski resorts and 285 pistes covering 400km2.
While there's plenty to keep you occupied in winter, summer's no slouch either. Come here to hike, mountain bike, zip-line, paraglide or soak up the sun in several outdoor pools.
Access from Switzerland is at Champéry in the Val d'Illiez.
