Pilot comments
C'est un site magnifique, probablement l'un des meilleurs de la région. Bon site de cross Bien prendre et garder du gaz. Ne pas passer en dessous de la vierge. Cela rend très difficile le retour vers l'atterro officiel. Ne pas descendre en vallée à Saint Jean de buèges. Zone de protection rapaces. Faire tout son possible pour rester au relief.
