The Boí Valley, known for its World Heritage Romanesque churches, is one of the main entry points to the Aigüestortes i Estany de Sant Maurici National Park and to forest and high mountain habitats that are home to rare birds. Several routes go through the National Park, but the Durro fauna route through forests and meadows, with great panoramic views, is especially recommended for birdwatchers, as is a visit to the Salencar de Barruera, a wetland area surrounded by mountains where migratory birds stop over.
