Lac de Retournemer, Glacial lake in Xonrupt-Longemer, France
Lac de Retournemer is a mountain lake in the Vosges region, situated in a basin carved by glacial activity. The water is surrounded by forests and hiking trails that offer views across the surrounding peaks.
This lake formed during the last Ice Age when glaciers in the Vosges carved deep valleys into the mountainside. Meltwater from retreating ice eventually filled the basin to create the lake we see today.
The lake and its surroundings received classification as Natural Monuments, reflecting the local commitment to environmental preservation and natural heritage protection.
The shoreline and surrounding trails are easily accessible and suitable for various fitness levels. Visitors should be prepared for rapid weather changes at this elevation and bring appropriate clothing.
The Vologne River flows through this mountain lake, which maintains an average depth of 11.5 meters throughout its natural basin.
