One of the wildest natural areas in Catalonia, its diverse landscapes range from the green meadows and lush forests of the Boumort and Carreu mountain ranges to the steep cliffs of the Collegats gorge. Birds of prey and mountain birds abound and the Boumort mountain range is the only place in Europe where all four species of European vulture can be found. In autumn, the bellowing of the stags is another great natural spectacle.
