GR®54 - Tour de l'Oisans et des Écrins depuis La Grave, par le GR®54C et les var

A long, very steep climb above Valjouffrey in Auvergne-Rhône-Alpes. The hardest 500 metres average 35.7% and come almost at once, before your legs have settled. Expect 77 to 130 minutes. At 38.0 TEP it is harder than almost every climb in the catalogue. Northwest-facing, so it stays cool and holds snow late. It is graded demanding mountain hiking: expect sections where you watch every step.
