Lac Blanc via Grand Balcon Sud

Located at 2,352m within the Aiguilles Rouges Nature Reserve, Lac Blanc is one of the most famous alpine lakes in the Haute-Savoie. The trail offers a front-row panoramic view of the complete Mont Blanc massif, including the Aiguille du Midi and the Mer de Glace. Starting from the La Flégère cable car station above Les Praz, hikers traverse the Grand Balcon Sud before ascending a series of rocky paths and assisted sections with metal ladders to reach the lake and its refuge. The route is iconic for its mirror-like reflections of the high glaciers and rugged red rock scenery. Note: Compiled from public sources — not a field report.

Route Typology: Highland Cloud Forest Trail Network. The Monteverde Cloud Forest Biological Preserve is a 10,500-hectare sanctuary in the Tilarán Mountains, protecting a rare high-altitude ecosystem where moisture-laden trade winds create a persistent shroud of mist. A network of approximately 13km of well-maintained trails leads through primary and secondary forest that hosts over 3,000 species of plants, including a high density of epiphytes such as orchids and ferns. The trails range from the high-altitude Sendero Chomogo to the moss-covered Sendero Pantanoso. It is a critical habitat for the resplendent quetzal and a showcase for tropical conservation.
