GR54© Tour de l’Oisans & des Ecrins

The GR54, Tour of Oisans and the Ecrins, runs around the Ecrins massif in the heart of the Ecrins National park, which was Europe's first high-mountain park. It totals 176 km in length and is considered to be one of the hardest long-distance path (GR paths) in Europe.

Descriptif GR54© Tour de l’Oisans & des Ecrins

Spend 11 days exploring beautiful peaks – the Meije and Barre des Ecrins – a few glaciers (from the Emparis plateau) and the superb Arsine, La Muzelle and Le Lautivel lakes.This route is for experienced walkers only, as it involves the crossing of several serious mountain passes at L’Aup Martin, La Vaurze, and La Muzelle… You can start this tour in mid-June, when the huts open, but risk finding large patches of névé snow, which can be difficult to cross. The best time to go is between 15 July and 15 September.

Passages through the Alps have always been busy - along valleys and from valley to valley over mountain passes - and Oisans is no exception. Its name comes from "Ucenii", a Gallic tribe that settled in the Romanche. The revolution organised the Dauphiné into three "départements", namely Isère, Hautes Alpes and Drôme.

The GR54 passes through the first two and habit has extended "Oisans" not only to cover the Romanche and Vénéon valleys, but also the Guisane, Vallouise, Champsaur, Valgaudemar, Valjouffrey and Valsenestre. Between July and September, hikers trample through the alpine pasture land and untamed valleys, admiring the marvels of the rocks and glaciers that many hikers have enjoyed before them. This is a harsh country, with untamed nature, deep, narrow valleys and plenty of natural obstacles on account of the high attitude of the mountain passes and late snowfall. This means that the footpath is not an easy walk in the park, yet this passionate adventure is perfect for those wishing to combine the joys of hiking with a love for the mountains.

Whatever your programme, make sure you keep a few days for exploring this magnificent area.
