The Miño River is the longest river in Galicia, with a length of around 315 km. It rises in the Meira mountain range, in Lugo, and flows into the Atlantic Ocean, between A Guarda (Spain) and Caminha (Portugal), forming the natural border between both countries in its final stretch. Along its course, the Miño crosses very varied landscapes, from mountains and valleys to vineyards and forests. It is also famous for its farming areas and for the production of wine with the Rías Baixas designation of origin.
