Bonnet Rouge

Highest point of the cliff - 1645 meters high - the Bonnet Rouge is one of the main ridge’s summits with the Serre de la Bouisse liking Serre to l’Epine. The quite steep path allowing you to get there is worth the effort because the view is very splendid. From up there, a 360° panoramic view opens on the Dévoluy, the Écrins, the Préalpes hilly area, Ubaye valley and Ventoux Mount.
