Wolf pen of Balouta Curiosity · Valle de Ancares, El Bierzo, León Image of Valle de Ancares, not of the place itself. The ruins of an old communal wolf trap, an enclosure with high walls and live bait from which the animal could not get out once inside. It survives at Balouta, the hamlet that also has the finest group of pallozas in the municipality. Photo: David Perez (CC BY 4.0) What to see and do in Valle de Ancares
