Formigueiros Peak Nature · Folgoso do Courel, Quiroga, Lugo Image of Folgoso do Courel, not of the place itself. At 1,643 metres it is the greatest height of the Serra do Courel, followed by Pía Paxaro, at 1,610; on its northern slope the Devesa da Rogueira shelters, protected from the sun by the bulk of the mountain itself.
