Home to many species of wetland birds, this lagoon and its shores form the ‘nucleus zone’ of Menorca’s Unesco Biosphere Reserve, a natural park protected from development. It's a safe haven for birdlife (kites and fish eagles for instance) and species like Lilford's wall lizards and Hermann's tortoises. The park’s information office is 1km off the Me5, Es Grau road. From here you can follow two easy, signed trails (a third leads from Es Grau), each lasting under an hour.
