About Arousa#

Arousa (Isla de Arousa) is an island municipality in the inner Ría de Arousa in the province of Pontevedra, Galicia, Spain; it is the only island that forms a full municipality in Galicia. The island is notable for its maritime economy and coastal landscapes.

The shoreline is characterized by beaches, small fishing harbors and mussel-raft aquaculture installations used for shellfish cultivation. Town areas provide services, seafood markets and local eateries focused on fishing and shellfish products.

Local economic activity has long centered on fishing and shellfish farming, which remain primary livelihoods for many residents. The municipality administers services for a resident population and visiting seasonal visitors.

Geographically the island sits within the Ría de Arousa estuary off Galicia’s Atlantic coast, in the province of Pontevedra, and is part of the Galician coastal ría system.

  • Unique municipal status: The island is Galicia’s only island municipality, with an economy strongly linked to fishing and shellfish farming.
  • Seafood production: Numerous mussel-raft installations and small fishing ports are visible around the island and in the surrounding Ría de Arousa.
