From the Mediterranean to the High Alps — one of Europe’s great mountain journeys
The GR5 from Nice to Briançon is one of the most dramatic and rewarding sections of France’s great north–south long-distance route. Beginning at the edge of the Mediterranean and climbing deep into the southern French Alps, this journey delivers a powerful sense of transition — from sea-level landscapes to high mountain passes shaped by altitude, weather, and time.
For walkers undertaking self-guided walking holidays and outdoor adventures, the Nice to Briançon GR5 offers sustained challenge and immersion. Stages are long, terrain is demanding, and progress is shaped by elevation rather than distance. The route passes through the high mountain landscapes of Mercantour National Park, where extended stages rely on remote refuges such as Refuge de Longon to cross exposed ground safely.
Beyond Mercantour, the trail continues through quieter high valleys and borderlands, passing close to remote settlements near Maljasset and into the lived-in mountain landscapes of Queyras Regional Natural Park, linking valleys, historic passes, and isolated communities by foot alone.
Rather than ending the journey, Briançon acts as a natural transition point. From here, the GR5 continues north into the high Alps on the GR5 Briançon to Geneva, carrying walkers toward the Mont Blanc region and onward to Lake Geneva. Taken together, these sections form one of Europe’s most serious and coherent long-distance mountain journeys.
This is not a route built for speed. It rewards careful planning, respect for conditions, and a willingness to move through the mountains day by day.

Explore the Route
Nice to Saint-Dalmas-le-Selvage
The route begins dramatically above the Mediterranean, climbing rapidly from coastal landscapes into the hinterland. Early stages pass through olive groves and forested valleys before reaching higher Alpine terrain.
Saint-Dalmas-le-Selvage to the Haute Tinée
The GR5 enters the high mountains of Mercantour National Park, with longer stages, higher passes, and increasingly remote terrain. Alpine meadows, larch forests, and open basins dominate.
Haute Tinée & Refuge Stages
This is one of the most demanding and atmospheric sections of the route. Walkers rely on mountain refuges such as Refuge de Longon to break long stages and cross exposed high ground safely.
Upper Alpine Crossings toward Briançon
Beyond Mercantour, the route continues through high valleys and passes that lead toward the Briançon area. Terrain remains serious, with extended days and classic high-Alpine scenery.
