Montagnon Lake

Montagnon Lake sits between the ridges of Mardas, Montagnon, and l'Escala at 2000 meters elevation in Pyrenees National Park. The water is fed by mountain springs and surrounded by steep slopes that protect it from wind.

The lake formed through natural geological processes during glacial movements in the Pyrenees thousands of years ago. These powerful forces carved out the valley and created the basin where water now collects.

Shepherds from nearby valleys use the area around the lake for traditional herding, keeping alive methods that have been passed down through generations.

The lake is reachable by several hiking trails starting from Aydius village, with options ranging from shorter walks to full-day treks. Summer months offer the easiest access, as snow typically clears from paths between June and September.

From certain viewpoints on the surrounding mountain peaks, the water forms an unusual heart shape when seen from above. This natural detail often goes unnoticed by visitors focused on the larger landscape.
