The dams and dikes built on the Limay River have modified the arid landscape of the steppe changing its shape and color. An instance of this is the Arroyito Dam, which carries bluish green waters and lodges leafy vegetation and varied bird species: everything necessary to become one of the most attractive spots in the area.
To reach this place, travel around 56 kilometers along Route 22 in the direction of the capital of Neuquén, where the indicated detour is located.
The vibrant turquoise of the lagoon formed when the arid materials were extracted to build the dam makes contrast with the green of the trees.
Biodiversity is represented by a considerable number of ducks, thrushes, mockingbirds, swallows, seagulls, egrets, cormorants, black-necked swans and avutardas which dwell in the surroundings and are object of bird-watching tours and photographic safaris.
