Takeoff description
on the top of the ski station. go by car to 'super-collet' and take the chair lift (open in winter and July-august). takeoff on the grass, near the ski tow.
Pilot comments
verry good site with south wind in winter: a lot's of time in soaring! But be careful in the valley, the wind could be stronger.
