Part of the municipality of Biscarrués, Erés is located on a plain on the banks of the Gállego River.
Its simple hamlet is home to the Parish Church of San Jorge, the village’s patron saint, who is honored during the annual festival on April 23rd.
Erés is also a stop along several trails that wind throughout the region: the trail that leads from the village to the iron bridge in Santa Eulalia de Gállego, where visitors can discover a beautiful riverbank forest; as well as the trail that connects this village with Concilio, along which visitors can enjoy the biodiversity of the Gállego river valley.
