Rules and notes
The national parc is just on your front when you are on the take off. Some area are forbiden, a map show you which one. Ask to the local instructors or local pilots. Someone will say you there isn't regulation, it's not true!!
Pilot comments
you are in high mountain, thermals could be strong in afternoon, in summer. XC is not so easy than in St Hilaire site or other sites in the front of alpes mountain (W). Don't use it if you are a biginer, or really early in the morning.
