@ScottKane: Of course it's a beautiful place - the whole EcoVia is lovely. The problem at this point, when we were there, was that it was difficult to get through. There were signs on the private property saying that no-one was allowed to walk through. And in rainy weather or high water, you couldn't get across the beach. Maybe that's different now?

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
