Access is via forest tracks in good condition. Obviously, to reach 2000m it takes a little time but the reward is worth it: the views are magnificent over the valleys and peaks at 360 degrees. A delight !

This great waterfall in the Surri ravine drinks from the waters of the Barbarisa lakes. Located at about 1,700 meters above sea level, its staggered shape actually causes several smaller waterfalls in addition to the main one.

This is the natural pass between the valleys of Chistau and Benasque. As such, it has been used for millennia and proof of this is the megalithic circle next to the track, which even then served to delimit border limits called "mugas".

The name of these lakes, at an altitude of 2,315 m, is a good example of the richness and linguistic diversity of Aragonese, since in the Benasque valley they are called "Barbarisa" and in the neighboring Chistau valley, "Barbaricia". All the Aragonese lakes are protected by being included in the Inventory of Singular Wetlands, therefore any activity that could modify the quality of their waters is prohibited. While bathing is not specifically mentioned, it is understood that bathing with chemicals on the skin such as sunscreen, deodorant, perfume, or lotion is negatively affecting water quality, so it cannot be done.
