The port of Porto do Son is located at the bottom of the Ría de Muros y Noia. It is an eminently active fishing ports. The Porto do Son municipal council has a privileged situation in terms of land communications, since it is 45 kilometers from Santiago de Compostela, and from a maritime point of view, because it forms the division between the Rias Altas and the Baixas. Agriculture, fishing and tourism are the main sources of income.
It is possible to climb to the top of Mount Enxa to see the entire estuary. The lagoons of Xuño, the medieval bridge of the same name, and the castro of Barão are of interest. The only pazo that is preserved is that of Nebra. Porto do Son is a tourist and summer resort; its beaches, placid and rugged at the same time, are suitable for surfing.
