The trail goes around the lake. A wooden boardwalk allows hikers to cross the most humid areas and the peat bog without damaging these fragile environments.
At the lowest point of the Lamoura lake combe, in a green landscape punctuated by the reddish hue of the surrounding peat bog, shine the waters of the highest natural lake in the Jura mountains.


Six unusual stops explain the valley's geological formation, how hydraulic power was once used along the water and present the aquatic life in the lake.

  • Welcome to Lamoura lake
  • The formation of the lake
  • About us, the lake's hosts
  • The peat bog
  • The life of the lake
  • Water saws and mills of the Lake's Combe

A module on this topic and the documentary "Tourbières, trésors cachés de la montagne jurassienne" (Peat bogs, hidden treasures of the Jura mountains) are a part of the permanent exhibition held in the Maison du Parc in Lajoux, 3 kilometers from the lake.
