Les Gets offers a wide variety of trails ranging from advanced to massochistic. This is the home of a World Cup downhill race and parts of the course are open to the public. Often the upper portion is closed off and blocked with electric fences. There is an "easier" downhill option than the pro course, but all trails here tend to be fairly difficult.
How to get there:
From Geneve take A40 to Cluses heading towards Milan. Then turn left onto D902 which will take you right to Les Gets.
Take the ski lift up and you'll see lots of trails below.
