Introduction
Mercantour National Park protects a dramatic stretch of the southern French Alps near the Italian border, where high peaks, glacial lakes, alpine meadows, Mediterranean influences, and historic mountain valleys meet. The park is known for wildlife, long-distance hiking, dark skies, and the rock engravings of the Vallee des Merveilles and Fontanalba.

Top Hikes
Mercantour hiking ranges from short lake walks to serious alpine traverses. Distances and elevation gain vary by trailhead and seasonal access, so use the official trail information and current conditions before committing to a route.
Lac d'Allos
Lac d'Allos is one of the park's classic day hikes, reaching a large high-elevation natural lake below Mont Pelat. Common round-trip versions are about 4.5 to 7.5 miles (7 to 12 km) with roughly 900 to 1,900 feet (275 to 580 m) of elevation gain, depending on the starting point and seasonal road access.
Vallee des Merveilles and Fontanalba
The Vallee des Merveilles and Fontanalba area combines mountain scenery with protected prehistoric rock engravings. Many visitors use routes from the refuge areas; plan on roughly 7 to 10 miles (11 to 16 km) and 1,600 to 2,600 feet (490 to 790 m) of gain for common day-route combinations. Stay on authorized paths and follow the special rules for the engraving zones.
Grande Traversee du Mercantour / GR52
The GR52 and related Mercantour traverse routes are demanding multi-day mountain trips across high passes, refuges, lakes, and remote valleys. This is the difficult option: sections can exceed 12 miles (19 km) and 3,000 feet (915 m) of gain in a day, with snow, storms, and refuge logistics shaping the plan.
Camping and Lodging
The park has mountain refuges and valley lodging around gateway towns. In the core of the park, camping is restricted; official guidance distinguishes camping from bivouac and allows bivouac only under posted rules, times, locations, and protection-area limits.
Safety and Planning
Mercantour weather can change quickly, especially above treeline. Check trail updates, refuge availability, road or shuttle access, storms, snowfields, and park regulations before hiking. Dogs, drones, wild camping, swimming, collecting, and route access may be restricted in protected zones.
