The Ria de Aveiro, also known as Foz do Vouga, is a lagoon that exists in the Aveiro region, between Ovar and Mira.
It is a shallow coastal lagoon with extensive intertidal zones, extending into the interior of Portuguese territory, parallel to the Atlantic Ocean, 45 kilometers long and with a maximum width of 11 kilometers. Its area covers two districts (Aveiro and Coimbra) and the towns of Aveiro, Estarreja, Ílhavo, Mira, Murtosa, Ovar and Vagos.
The ria is divided into three channels/zones: the Ovar Channel, the Ílhavo Channel and the Mira Channel.
Characteristics
The ria is the result of the retreat of the sea, with the formation of coastal ridges that, from the 16th century onwards, formed a lagoon that constitutes one of the most important and beautiful geographical features on the Portuguese coast.
In total, the entire mouth covers eleven thousand hectares, of which six thousand are permanently flooded, it unfolds into four important channels branched into streams that surround numerous islands and islets. The Vouga, Antuã, Boco and Fontão rivers flow into it, with the only communication with the sea being a channel that cuts the coastal line between Barra and São Jacinto, allowing access to the port of Aveiro for vessels with deep drafts.
Rich in fish and water birds, it has large areas of water, ideal places for practicing all water sports. Furthermore, even though it has been losing, from year to year, the importance it once had in Aveiro's economy, salt production, using ancient techniques, is still one of the most characteristic traditional activities of the city of Aveiro.

The Cáster river has its source in the parish of Sanfins, in the municipality of Santa Maria da Feira, crossing several parishes in that municipality and others in the neighboring municipality of Ovar, until it flows into the Ria de Aveiro, which has its northern limit in Carregal. Associated with this river, particularly through fishing and agriculture, have long been residents of Ribeira de Ovar who have depended on its quays — since the mid-18th century — to transport goods between Aveiro, Porto and other lands further inland. interior.
