An adventure that is taking shape

Although the trails in each area already existed almost in their entirety, the GRP® du Tour de l’Obiou was born out of a shared desire on the part of the Matheysine, Trièves and Dévoluy areas to create a trail around one of the giants of the Dévoluy massif: the Obiou.

With its vast open spaces, wild environment and varied biotopes, it seemed obvious to share this not-to-be-missed adventure with seasoned hikers.

The Tour de l’Obiou consists of 4 yellow and red signposted stages, covering 64km and 3490 metres of ascent.

This hike takes you around the Obiou, an emblematic summit of the Alps rising to 2,789 metres. For experienced hikers only, this four-day tour takes in spectacular and varied scenery, with lively mountain pastures, forests, ridges and wide open spaces.

A remarkable natural heritage

Nestling in the north of Dévoluy on the border between the Isère and Hautes-Alpes departments,Obiou never ceases to fascinate mountain enthusiasts. At 2789m, it is the highest peak in the massif. Recognisable by its limestone rock, you will gravitate around it at different altitudes and discover it from different angles during your adventure.

Walking around Obiou is like exploring a sensitive part of the mountain: you’ll discover a territory that has been inhabited and worked for over 2,000 years, inviting you to observe its fragile balance, while learning to move carefully in a preserved environment.

Lulled by the sound of birdsong echoing through the valley and the ringing of herds, you’ll be able to observe the fauna and flora of the mid-mountain region. Let yourself be transported by these breathtaking landscapes among chamois, marmots, golden eagles and herds of sheep and cows. You won’t be disappointed by this little corner of paradise!
