Takeoff description
Nice takeoff place for nearly every wind direction. The south takeoff is steep and not for beginners, when it is windy, but you can walk down to the lower south takeoff, which is easy for takeoff. The west, north-west and north takeoff are also suitable for beginners. --- Be aware of the wind funnel at the mountain pass (landing-area)
