To the north, Muros, hidden at the foot of the Louro mountain, Noia, and to the south Porto do Son are boundaries of this beautiful and calm estuary. The origins of Muros and Noia date back to the Middle Ages. Both preserve a historic quarter that speaks of a noble past linked to the sea and rocks: houses with coats of arms on their façade, arcaded streets, churches and small squares.

The Galician writer Otero Pedrayo referred to Noia as "the little Compostela".

Porto do Son, a fishing village which still preserves its flavour, is one of Galicia's foremost summer destinations. Next to it is Portosín, with a modern marina and its popular yacht races.

The estuary also offers countless beaches, most with golden white sand such as the beaches of Ancoradoiro, San Francisco, Aguieira, As Furnas or Basoñas.

There are also many archaeological remains and "castros" (ancient fortifications), such as the magnificent Castro de Baroña, by the sea and overlooking a marvellous beach.
