Pambre Trail Activity · Palas de Rei, Ulloa, Lugo Image of Palas de Rei, not of the place itself. Route of medium difficulty that sets out from the surroundings of the castle, in the parish of Ramil, and drops down to the Mácara torrents among chestnut trees and riverside woodland, with some natural crossings that call for care.
