Arguis is the typical town of the Huesca Pre-Pyrenees with stone houses and nestled under a limestone ridge covered with trees. Opposite the town is the homonymous reservoir, the oldest in Aragon, where the waters of the Isuela River are dammed. The landscape as a whole formed by the sheet of water and the crests of the Pyrenean foothills is enchanting.
