Illa de Arousa Causeway Drive
Just 8 km north of Cambados, a 1.2 km concrete causeway connects the mainland to Illa de Arousa — the only inhabited island in the Rías Baixas accessible by road. Most visitors to Cambados never make the short detour, which makes it feel like a genuine secret.
The Island Itself
Illa de Arousa is a low, pine-covered island of about 5 km², ringed by quiet beaches and mussel-farming platforms called bateas that stud the ría in every direction. The village at its centre has a fish market, a handful of seafood restaurants and almost no tourist infrastructure.
Praia de Area das Pipas on the island's western shore is a sheltered sandy beach with calm, shallow water — excellent for swimming in July and August when the Atlantic warms enough to be genuinely pleasant.
What to Do There
Rent a bicycle from one of the two hire shops near the causeway entrance and loop the island's perimeter path in around two hours, stopping at viewpoints over the mussel platforms and the open Atlantic beyond.
The island's small Museo do Mar gives context to the mussel and oyster farming that defines the local economy — entry is cheap and the exhibits are surprisingly engaging, with old fishing boats and traditional gear on display.
