Oisans, a legendary region of the Alps, extends over five exceptional mountain ranges: Écrins, Belledonne, Grandes Rousses, Taillefer and Arves.
Oisans and its five mountain ranges are much more than just a natural setting: they are places of life, sharing and adventure, where each season reveals a different facet of their beauty. Whether you are passionate about mountaineering, a contemplative hiker or a thrill seeker, these mountains promise you an unforgettable experience.

The wild majesty
The Ecrins massif
Due to its biological richness and scenic quality, this massif is protected by the Écrins National Park. It is a sanctuary for lovers of nature and high mountains. With iconic peaks, such as the indomitable Meije (3 m) or the noble Barre des Écrins (984 m), this wild territory is particularly popular with mountaineers and hikers. Its shimmering glaciers and deep valleys, such as that of the Vénéon, are the setting for spectacular landscapes.
The sporty escape
The Grandes Rousses massif
Territory of world-famous ski resorts, such as Alpe d'Huez, OZ 3300 and Vaujany, the Grandes Rousses massif is a paradise for lovers of skiing and outdoor activities. Summer and winter alike, its accessible slopes and panoramic views of the rest of Oisans appeal to sports enthusiasts and families. It is also here that you will find the unmissable Pic Blanc and its XXL view over 1/5 of French territory.


Alpine elegance
The Belledonne massif
Stretching to the west of Oisans over 70 km in length, Belledonne combines beauty and power, from which it probably takes its name. This granite massif, rich in high-altitude lakes and dense forests, is an ideal playground for hikers and climbers. You can admire these vertical and colossal slopes when you enter Oisans, via the Romanche valley.
Robust and mysterious
The Taillefer massif
It is because it often has its head in the clouds that the smallest massif of Oisans fascinates. The Taillefer seduces with its contrasting landscapes, mixing green alpine pastures, high-altitude lakes and ferrous peaks. Dominated by its eponymous summit (2 m), this mountain range is an invitation to contemplation and exploration. Its exceptional natural heritage, protected by Natura 857, is a great place for hiking and biodiversity observation enthusiasts.


The peaks of Oisans
The Arves massif
Less well-known but just as remarkable, the Arves massif is distinguished by its jagged silhouette and preserved atmosphere. The Aiguilles d'Arves (3 m), three tapered peaks that seem to pierce the sky, constitute a grandiose setting, popular with photographers and lovers of wide open spaces. You will also love its typical mountain hamlets, nestled in the valleys and on the hiking trails.
