Tour des Écrins (GR54)
A demanding high-altitude circuit around the glaciated Écrins massif, one of the most alpine of France's classic tours.
Route overview
The Tour des Écrins, waymarked as the GR54, circles the Écrins massif in the Écrins National Park in the Dauphiné Alps of south-east France. It is considered one of the more physically demanding of France's classic multi-day tours, crossing numerous high passes above 2,500 metres with sustained daily ascents and descents. The route passes beneath glaciated peaks including the Barre des Écrins, France's southernmost 4,000-metre summit, and links a network of refuges managed largely by the Club Alpin Français and the national park authority. Scenery includes glacial valleys, high tarns and remote pastoral hamlets. Most hikers complete the loop over ten to twelve days, staying in mountain refuges. Good fitness and comfort with exposed terrain and via ferrata-style sections in places are recommended.

Safety context
High mountain passes are exposed to sudden weather changes; snow can persist into early summer on the highest cols. Refuge reservations are essential in peak season.
Several passes exceed 2,700 m; altitude and long daily ascents catch out hikers underestimating the tour's difficulty compared with lower-altitude French GR routes.

Why find a buddy
High alpine passes and remote refuge stages are safer and more manageable with a partner, particularly for stream crossings and route-finding in poor visibility.
