Hike to the stunning Lac d’Oô, a beautiful glacial lake nestled in the Pyrenees. As you approach the lake, you’ll be treated to breathtaking views of its clear, turquoise waters, surrounded by sheer cliffs and lush forest. The hike is moderately challenging, with rocky paths leading to a perfect viewpoint where the lake and surrounding peaks create a truly picturesque scene. Take some time to appreciate the tranquility of the area, where you can also catch a glimpse of the impressive Oô waterfall cascading down the mountainside.

Next to the Lac d'Oô bivouac you have the best point of view, the most axial, to admire the Lac d'Oô waterfall.

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.
