Magnificent lake! Accessible to all! As a bonus, you'll find ibexes and a few marmots if you're lucky. For the more courageous, you can climb to an altitude of 2,900 m by continuing on the path with a magnificent view if the sky is clear!

Busy in summer. The parking lot near the start fills up quickly, but you can also arrive earlier. Beautiful panorama.

To help preserve these fragile natural environments, visitors are encouraged to stay on marked trails to prevent erosion and protect sensitive vegetation.
