Mero River Nature · Cambre, Coruña, A Coruña The Mero river rises in the Tieira mountains and, after about 41 kilometres, crosses Cambre from the Abegondo-Cecebre reservoir to its mouth in the ría del Burgo; its floodplain, with alder woods and mills, forms part of the Mariñas Coruñesas biosphere reserve. The reservoir, at its confluence with the Barcés river, is a special area of conservation and supplies drinking water to the A Coruña area. In the past it was navigable as far as the port of Sigrás, with barges supplying A Coruña's Casa de la Especiería, and is today limited by the A Barcala dam, whose removal the then mayor of Cambre, Antonio Varela, requested unsuccessfully in 1990. Channelling works on its final stretch were completed in 2007, and it now has a small jetty at O Temple for small boats. Photo: Nemigo (CC0) What to see and do in Cambre
