A nice place to stop off after the hike. The car park is generously dimensioned, since the Lac d'Oô and the Lac d'Espingo are popular hiking destinations, you should still come early to get a parking space.

Lac Vert, made up of three basins, is located at an altitude of 2,004 metres. Nestled at the foot of the Pic du Maupas in a green setting, this lake suggests a pleasant break.
