Lac Blanc, Glacial lake in Haute-Savoie, France.
Located at 2352 meters altitude, Lac Blanc measures 180 meters in length and 145 meters in width, reflecting the surrounding Mont Blanc massif.
The lake formation occurred during the last glacial period when ice movement carved out the depression in the mountainous landscape of Haute-Savoie.
The lake functions as a central point for mountain photography, attracting nature enthusiasts who document the changing colors throughout the seasons.
Access requires a three-hour hike from either Col des Montets or Argentière village, with the option to reduce walking time using the La Flégère cable car.
Environmental regulations prohibit swimming and dish washing in the lake to maintain the water quality and protect the high-altitude ecosystem.

The lakes of Auvergne-Rhône-Alpes showcase remarkable geological diversity. The natural glacial lakes such as Bourget and Annecy contrast with the deep volcanic lakes of Pavin and Bouchet. The artificial lakes of Serre-Ponçon and Monteynard complete this hydrographic network. This region includes high-altitude lakes in the Alps and the Massif Central, plains water bodies, and hydropower dam reservoirs.
Occitanie hosts a wide variety of lakes spread between the Pyrenees and the Massif Central. Natural lakes mainly occupy high-altitude zones in the Pyrenees, where glacial erosion has carved out cirques and basins now filled with water. Lake Oô, located at 4,950 feet (1,507 meters) altitude, receives water from a 984-foot (300-meter) waterfall descending from Lake Espingo. The Bastan lakes form a series of three linked water bodies between 7,217 and 8,202 feet (2,200 and 2,500 meters) near Barèges, while Lake Bethmale, at 3,498 feet (1,065 meters) in Couserans, is surrounded by beech forests. Artificial lakes in the region serve various functions, including water storage, hydroelectric power, and recreational activities. Lake Salagou, created in 1969 in Herault, stands out for its distinctive geological setting: red rocks rich in iron give the landscape a reddish-brown hue. Lake Pareloup, covering about 3,485 acres (1,410 hectares) in Aveyron, is one of the largest reservoirs in the area. Lake Saint-Ferréol, built in the 17th century at the foot of the Black Mountain, supplies the Canal du Midi and demonstrates historic hydraulic engineering. These lakes offer opportunities for hiking, sailing, and windsurfing, especially at Lake Ganguise where the wind blows roughly 300 days per year.
