Takeoff description
Features: The take off is very nice although not large. The slope is constant without any technical difficulty. Notes: The takeoff is not feasible in the winter because it is impossible to achieve with the snow. Obstacles: None. Top Landing: No. Notes on the flight: The cable car is open from November to April and from mid June to mid September. The ticket includes a return if you do not take off
