Welcome to Valles de Hecho & Ansó
These enchanting parallel valleys, tucked away in Aragón's far northwest corner, run up through dense mixed woodlands, punctuated by a few ancient stone-built villages, between crags of increasing height and drama, where raptors circle high above, to end at the main Pyrenean ridge along the French border. Flowing south from these mountains, the Río Aragón Subordán and, a few kilometres to its west, the Río Veral have carved out the Hecho (Echo) and Ansó valleys. Little known to non-Spaniards, the valleys and their surrounding mountains are a paradise for walkers, with rivers, lakes, gorges and waterfalls, as well as spectacular mountain scenery and plentiful accommodation. The upper parts of the valleys are part of the 270-sq-km Parque Natural de los Valles Occidentales.
