A demanding mountain itinerary
The Tour de l’Oisans et des Écrins, also known as the GR®54 is 176 km long with an accumulated height difference of 12,000 metres and goes over 14 cols. It’ss one of the three long-distance hiking trails in the French Alps with those of Mont Blanc and la Vanoise. It starts in Bourg-d’Oisans and goes through the sumptuous Alpine landscapes of L’Oisans and the Écrins National Park, and past the highest peaks of the range. It is also considered to be one of the most difficult GR® in Europe! Particularly due to late snow and certain parts with very steep slopes or slippery schist. It is therefore for seasoned hikers and can be done on average over twelve or fifteen days, with the possibility of only doing some sections for a shorter hike.
