A splendid circuit around the Montbrison massif against a backdrop of pine forests, alpine pastures and cliffs, its high point being a stunning crossing over the Col de Vallouise.

“This is a mega-itinerary. Of course, the highlight is the crossing over the Col de Vallouise, at the end of a long climb. A splendid descent through alpine pastures awaits us, before entering the forest again.” Marie-Geneviève Nicolas, park ranger at the Parc National des Écrins.
