Hecho Valley & Selva de Oza
Valle de Hecho
A river valley in western Aragon, with stone-built villages, a 9th-century monastery and high-mountain fir and beech forests.
The Hecho Valley lies in the western Aragonese Pyrenees, within the Valles Occidentales Natural Park. At the valley mouth, the town of Hecho preserves stone-built houses and local dialect traditions. About 2 km upstream, the village of Siresa has the church of the Monastery of San Pedro. The monastery is traditionally dated to the 9th century and is the northernmost monastery in Aragon. The surviving church has a Latin-cross plan, was declared a national monument in 1931, and legend holds that the Holy Grail was once discovered here. Continuing up the Aragón Subordán River, you enter the Selva de Oza. Mixed forests of fir, pine and beech are the park's most representative scenery, and the classic hiking route from here leads to Acherito lake. The valley also has remains of an ancient Roman road and a centre showcasing megalithic culture. It is about 1.5 hours' drive from Torla and is best given a full day to itself.
