Beautiful views of the Escales Reservoir, close to the Fuente de la Mena car park, from where the water path route begins. On days when the water is at a low level, we will see the ruins of the Monastery of Santa María de Lavaix.

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
