The valley of the River Navea is a protected landscape. It is dominated by trees, such as the large forest of San Xoán de Río or the famous chestnuts in the district of Trives. The historical chestnuts share space with interesting buildings that are being rehabilitated called sequeiros, traditionally used to dry chestnuts.
There is a mediaeval bridge over the River Navea, built on the remains of the ancient Roman bridge. This river flows into the River Bibei, whose channel is crossed by one of the best preserved Roman bridges in Galicia, built for the passage of the Vía Nova or 18th Via of the Antonine Itinerary, whose route was completed about the year A.D. 80.
