Takeoff description
Property of the Club Celtic de Vol Libre. Not for beginners : take of area is, like the car parking area, under effect of rotor due to the shape of the slope. Hang gliders : take care about the wind direction, trees of both side are very close ; those trees on the bottom are enough high to put you in trouble (rotor) in windy condition.
