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.
