A typical mountain landscape, formed by an abrupt labyrinth of forest and rocks around the wonderful canyon. “Estrets d'Arnes” is one of the most beautiful spots in the Els Ports mountain range, the wildest mountains in southern Catalonia. The area includes more than 450 ha of canyons and ravines amidst pine forests, thickets and meadows, at the westernmost end of the Els Ports Natural Park.

The Estrets river, the main artery of the area, runs sinuously jumping from pond to pond among the rocky formations that form some amazing walls.
