The Ria Formosa, a wetland of international importance, is a labyrinth of channels, islands, marshes and sandbanks that stretches for 60 km, specifically between the beaches of Garrão and Manta Rota, on the Algarve coast. Its diverse ecosystems attract a wide variety of animals, including, of course, numerous species of birds such as the purple crake, the park's symbol. If you want to admire this bird with its magnificent plumage and learn all about the protected area, start your visit with a visit to the Marim Environmental Education Centre. There you will receive information on the most suitable hiking trails and the shelters where you can hide to observe the different species in their natural environment. The park also organizes trips on an old boat that was originally used for tuna fishing. https://www.visitportugal.com/en/content/parque-natural-da-ria-formosa

The park also organises trips on an old boat originally used to catch tuna. One of the friendliest and most trusting animals you will come across here is the Portuguese Water Dog. This is a long-haired breed of dog that used to help fishermen with their work, diving to the nets and bringing in the fish that got caught in them. In addition to fishing, salt production and the gathering of mollusks and shellfish are traditional activities of the inhabitants of the estuary, who have never lacked ingenuity and craftsmanship. This is how the recipes for delicious gastronomic specialties such as fish soup and rice with razor clams were created, which you can try in the restaurants by the sea. visitportugal.com/de/content/parque-natural-da-ria-formosa
