Bourg-Saint-Maurice Marshland

This nature spot with a leisure centre deep in the Tarentaise region is home to many birds (including as a stopover habitat for migrating birds) and is the only known site for Natterjack Toads in this valley. Several streams and rivers, including the Isère, join here to form the lake. Known as an equalising reservoir, it contributes to the smooth running of the Malgovert hydroelectric power plant. Picnic tables and water supply points.
