Les Portes du Soleil is a major ski sports destination in the northern French alps
(Chablais Alps) encompassing thirteen resorts between Mont Blanc in France and Lake Geneva in Switzerland.
With more than 650 km of marked pistes and about 200 lifts in total, spread over 14 valleys and about 400 square miles (1036 square km) Portes du Soleil ranks among the two largest skiareas in the world (the other being Les Trois Vallees).
Almost all of the pistes are connected by lifts – only a few marginal towns can only be reached by the free bussservices in the area. Highest point of skiing is approx 2.400 metres and the lowest is approx 900 metres.
As with many other Alpine ski resorts, the lower slopes of the Portes du Soleil have snow-making facilities to extend the skiable season by keeping the lower slopes open during the warmer months.
