Les Portes du Soleil is a major skisports destination in the 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 1,036 square kilometres (400 sq mi), Portes du Soleil ranks among the two largest ski areas in the world. Almost all of the pistes are connected by lifts – a few marginal towns can be reached only by the free bus services in the area. The highest elevation accessible on skis is 2260 m and the lowest is 930 m. As with many other Alpine ski resorts, the lower slopes of the Portes du Soleil have snow-making facilities to extend the ski season by keeping the lower slopes open during the warmer months.

Avoriaz is a French mountain resort in the heart of the Portes du Soleil. It is located in the territory of the commune of Morzine. It is easily accessible from either Thonon at Lake Geneva or Cluses station on the A40 motorway between Geneva and Chamonix. Either way one follows the D902, Route des Grandes Alpes, to Morzine and then the D338 running from Morzine to Avoriaz. Snow chains are often necessary. Avoriaz is built on a shelf high above the town of Morzine, which is among the pioneering towns of skiing with its first lifts dating back to the early 1930s. Today Avoriaz is one of the major French ski destinations catering for all standards of skiing and ranks among the top snowboarding destinations of the world. Apart from snow-based pursuits, Avoriaz is also a centre for trekking, golf, VTT and other outdoor activities during the summer. Cars are forbidden in Avoriaz. The resort is designed to be fully skiable. Other transport around the resort includes horse-drawn sleighs and snowcats during winter.
