Waterfall of os Portelos Nature · A Ribeira de Piquín, Meira, Lugo Image of A Ribeira de Piquín, not of the place itself. A waterfall surrounded by centuries-old oaks and chestnuts, one of the most celebrated spots in the concello and the goal of one of its waymarked routes; the woodland covering it preserves the traditional uses of the chestnut grove.
