East of Geneva, the Les Crosets Ski Area has dozens of lifts accessing tons of freeriding.
Les Crosets is a very small resort town that is popular with the snowboard crowd due to the terrain park, The SuperPark, which is known for its big kickers, boxes and rails.
For some basic freeriding at Les Crosets, head up the Mossette-Suisse chairlift. Turn left and come back down the steep face under the chairlift.
If you are looking for some challenging boarding, there are several options. Check out the Pointe de Lau Couloirs or the Pierre Plate Couloir near Touassiere. Also, Aigulle des Champeys is worth checking out.
The Les Crosets Ski Area is part of the Portes du Soleil ski domain. The Portes du Soleil ski domain is one of the largest in the world linking 14 villages on both sides of the Swiss-French border southeast Geneva. The very family-friendly Portes du Soleil encompasses 206 lifts serving 283 pistes totalling 650km over 400 hectares of terrain. The pistes are classified as 41 green, 104 blue, 110 red and 28 black. From a snowboarders perspective, the classifications at Portes du Soleil can be translated as green means walking, blue means occasional walking, red means intermediate and black means difficult. In addition to the groomed pistes, there is plenty of off-piste terrain to explore under craggy peaks and down steep couloirs. Keep in mind that there are plenty of t-bars and Poma platter lifts spread throughout the region, along with flat or rolling traverses between ski areas. Overall, you are not going to find many snowboarders here, maybe 15%, except up at Avoriaz. By the way, Avoriaz makes for a great central and high elevation base to explore the entire Portes du Soleil region and it has exceptional terrain in every direction. Since the region tends to be lower in elevation, snow depth can be a problem throughout. If the quoted minimum depth is less than 60cm (24 inches), the off-piste routes are pretty sketchy to explore and you will be stuck on the icy groomed pistes. There can be some inconsistencies in published snow reports, such as centimeters reported as inches, so make sure to check several snow report sources before coming.
