Crowded on the way there. Avoid weekends, but the return trip takes you along small paths with magnificent views. https://youtu.be/Ok7Ho9e7DwM?si=Zw-F5dc7hrTHr3sT

A beautiful lake located at 1,905 m in a glacial cirque surrounded by Pico del Verde (2,295 m) and Peña Sabocos (2,757 m). It has a maximum depth of 25 m and is close to the Asnos Lake.

Area where there is a set of Ibones in a rather stony mountain area due to its height. From this point you can see a large number of peaks in the area such as the Pico de Arnales, the Gramo Negro, the Aguja de Pondiellos, the Algas and the Argualas.

Evident. And this includes dogs too. It is all too common to see how people allow their pets to take a dip.

The Ibones de Brazato are two lakes of glacial origin. The Brazato Bajo ibón is at 2,370 meters, while the Brazato Superior is at 2,450. The climb from Panticosa is arduous, but it is worth it for the beautiful views of peaks such as Arnales, Gramo Negro, Aguja de Pondiellos, the Algae and the Argualas.

All the Aragonese lakes are protected as they are included in the Inventory of Singular Wetlands, so 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 sunscreens, deodorants, perfumes or creams is negatively affecting the quality of the water, so it cannot be done. You can read the protection decree and the list of wetlands included here: boa.aragon.es/cgi-bin/EBOA/BRSCGI?CMD=VEROBJ&MLKOB=558856590404
