Ostraveiro is located in Marinha Passagem, on an twenty-acre property, surrounded by the Ria de Aveiro canals, only reachable by boat.

The natural and unique characteristics of its waters make it ideal for shellfish production. In addition to the shellfish production component, Ostraveiro arranges guided tours to the oyster and clam production. Visitors can learn a lot about shellfish, samphire, and existing fauna and flora.

The visit culminates with the tasting of all products. It is Aveiro’s one-of-a-kind offer that prioritizes sustainable and nature tourism.
