Lac Bleu de Lesponne, Mountain lake in Hautes-Pyrénées, France
Lac Bleu de Lesponne is a mountain reservoir nestled in the Hautes-Pyrénées at about 2000 meters elevation, surrounded by rocky peaks and grassy slopes. The water sits in a natural basin formed by stone cliffs and meadowland.
The lake took shape during past ice ages when glaciers carved deep valleys into the Pyrenean landscape. This geological action created the basin that now holds the water.
Local shepherds have traditionally moved their flocks across the surrounding alpine meadows, following routes that remain visible today. Their presence has shaped how people experience the landscape and its rhythm throughout the seasons.
Reaching the lake involves a several-hour hike from Le Chiroulet along marked mountain trails with steady elevation gain. Weather conditions at this altitude can change quickly, so proper hiking gear and wind protection are advisable.
The water reaches an exceptional depth of about 135 meters, making it one of the deepest lakes in the Pyrenees. This depth keeps the water remarkably cold even during warmer months.
