Rianxo’s economy has long been tied to the sea, with fishing and shellfish farming playing a crucial role in the town’s prosperity. The estuary provides ideal conditions for mussel and clam farming, and Rianxo is known for producing some of the finest seafood in Spain. Visitors can sample this fresh produce in local markets and restaurants, making seafood a key part of the city’s gastronomic appeal.
Tourism is also an important industry, especially during the summer months when the town sees an influx of visitors. The local economy is supported by small businesses, many of which are family-run, focusing on traditional crafts, agriculture, and hospitality services. The production of traditional Galician wines, such as Albariño, is also growing, adding to Rianxo’s economic landscape.
Local craftsmanship includes the creation of wooden products and fishing-related tools, giving visitors the chance to purchase unique, handmade souvenirs while supporting the local economy.
