Parque Natural da Ria Formosa
This sizeable system of lagoons and islands stretches for 60km along the Algarve coastline from west of Faro to Cacela Velha. It encloses a vast area of sapal (marsh), salinas (salt pans), creeks and dune islands. The marshes are an important area for migrating and nesting birds. You can see a huge variety of wading birds here, along with ducks, shorebirds, gulls and terns. This is the favoured nesting place of the little tern and the rare purple gallinule.
