one of the 7 natural wonders of Portugal
Lagoon system
In this vast wetland there is a wide variety of aquatic and terrestrial habitats:
salt flats, sandbanks , dunes, salt pans, fish farms, freshwater and rant water lagoons, watercourses, riparian vegetation, agricultural areas, forests and pine forests.
This is revealed in the great faunistic and floristic diversity that can be found there. The lagoon is protected from the sea by a discontinuous line of narrow dunes, which form five barrier islands and two peninsulas.
About 3,600 ha are permanently flooded.
