Lacs de Frémorte, Lac Nègre, and Lac de Graveirette Loop

This specific loop is rated as moderate. While some longer, more comprehensive routes in the area can be difficult, this particular komoot tour covers approximately 12.4 km with an elevation gain of around 594 meters, making it accessible for hikers with a good level of fitness.

The terrain is quite varied. You'll traverse through lush larch and pine forests in lower sections, transitioning to more rocky, mineral environments at higher elevations. Expect some stony areas ('pierriers') and glacial moraines. Around Lake Graveirette, some sections can be marshy. The path often follows ancient military tracks, which can be wide, but also includes steeper, sandy corridors and grassy slopes.

The loop offers magnificent panoramic views and diverse landscapes. Key features include the dark waters and ochre granite cliffs of Lac Nègre, the serene high-altitude Lacs de Frémorte, and the peaceful, emerald waters of Lake Graveirette, often surrounded by larches. You'll also experience cross-border views into Italy's Parco Naturale Alpi Marittime, with vistas of the Argentera massif.

Specific parking details are not provided in the tour data, but trails in this region often start from areas like Boréon or Salèse. It's advisable to check local information or the komoot tour details for the precise starting point and parking availability before your visit.

The best time to hike is typically from late spring to early autumn. You can enjoy vibrant rhododendrons in bloom from late June to early July, or witness the stunning golden larches and red-orange blueberry bushes in mid-October. Summer offers pleasant conditions, but always check weather forecasts for the high mountains.

As this loop is located within Mercantour National Park, dogs are generally not allowed, even on a leash, on the trails within the park's core zone. This regulation is in place to protect the local wildlife. Always verify the latest park regulations before bringing your dog.

While the lakes are beautiful, wild swimming in high-altitude glacial lakes like Lac Nègre, Lacs de Frémorte, and Lake Graveirette is generally discouraged or prohibited in national parks to protect fragile ecosystems and for safety reasons due to cold temperatures. Always respect park regulations regarding water activities.

For a moderate hike of this length and elevation, sturdy hiking shoes are essential. Pack layers of clothing suitable for changing mountain weather, including rain gear. Bring plenty of water, snacks, a map or GPS device (like komoot's app), sun protection, and a first-aid kit. Trekking poles can also be helpful on varied terrain.
