The main source of wealth of this municipality is fishing, while crops are mainly used for self-consumption. Bueu has an endless number of natural beaches on its more than 10 kilometres of coastline, as well as the beaches of Ons Island, a protected area within the National Park of the Atlantic Islands of Galicia which is an increasingly important focus for tourism. This area also offers a wide variety of trails, routes and protected natural areas that are perfect for hiking and nature watching. Cabo Udra is a natural enclave, catalogued within the Natura 2000 Network. The importance of fauna and flora is highlighted in the Nature Classroom, one of the few interpretation centres with the distinctive Blue Flag in Galicia, which endorses its commitment to environmental education on sustainable development and coastal ecosystems. The local gastronomy boasts of the seafood and fish that its inshore fleet catches daily in the Ria de Pontevedra and the surroundings of the island of Ons. The Bueu octopus, of well-renowned quality, shows the distinctive “Polbo de Rías” and stars in a gastronomic festival in August.
