In the heart of the nature reserve, Pormenaz lake sits perched at an altitude of 1,945 m in the small Pormenaz Massif, which forms part of the Aiguilles Rouges crystalline range.
Contemplate Mont Blanc from a different angle. Travel a few kilometers out of Chamonix and find yourself alone, like the great explorers in their time. Pormenaz is still the preferred terrain of shepherds and loners. From this long crest, a dreamy mountain landscape is revealed.
- TipsBeware, high altitude lakes are fragile! Please respect the area: do not swim or wash your dishes, do not trample the wetlands, do not put water sports equipment (buoys, paddles, etc.) in the water or throw anything into the lake (stones, waste).
