The municipalities that form the geodestination are: Catoira, Pontecesures, Valga and Vilanova de Arousa.

The name of this geodestination already reminds us of the Way of Saint James. On one side, the Mar de Arousa-Río Ulla Route, with the municipalities of Vilanova de Arousa and Catoira, and on the other, the Portuguese Route with the municipalities of Pontecesures and Valga. The Ulla river is the backbone of this geodestination with a spot in the middle of the Arousa estuary, beyond the mouth of the river.
