Meanders of the Nora Nature · Las Regueras, Oviedo, Asturias Incised meanders of the Nora river along the stretch before its confluence with the Nalón, between San Pedro de Nora and the Priañes reservoir, separating the concejos of Oviedo and Las Regueras; its 72 hectares were declared a natural monument by Decree 16/2003, of 13 March. The riverbank holds extensive stands of white willow and, within the area of influence of the Priañes reservoir, a holm oak wood; wildlife includes several species of wintering birds and the common frog. Geologically it lies in the region of folds and thrust sheets of the Asturian zone of the Cantabrian massif. Photo: Amasuela, Luis Lafuente Agudín (CC BY-SA 4.0) What to see and do in Las Regueras
