Takeoff description
Two take-offs on each side of the 'col des Aravis' pass : - south at the top of the Etale lift ; west or east ; - north on the different ski slopes ; any open lift in summer ?
Pilot comments
Good start for beautiful and easy XC flights over the Aravis. Nice area for XC, easy to fly in all directions.
