Main views of Lac de Oô and its waterfall.

This lake located at 2339 m altitude is undoubtedly one of the most visited in the Benasque valley, due to its proximity to Llanos del Hospital. All 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 sunscreen, deodorants, perfumes or creams is negatively affecting the quality of the water, so it cannot be done.
