Covering more than 23,000 hectares (57,000 acres), the Sado Estuary Nature Reserve in Setubal was established to protect the estuary.
The inner part of the estuary is bordered by rice-fields and reedbeds, whereas the north-western limits are densely populated and the south-western parts are sheltered from the open sea by a sandbar.
The Sado estuary has been declared a reserva natural (23,971 ha), Ramsar Site and a Special Protection Area for Birds (SPA), largely on account of the 300-plus species of vertebrate recorded here.
It is a special place for birdwatching, including white storks, herons and flamingos.
The fish species include white bream, grey mullet, skate, sole and the Lusitanian toadfish.
Bottle-nosed dolphins in their natural habitat can be seen and there is an important colony of them in the River Sado.
They’re often observed while crossing the river by boat, between Setubal and Troia. Cockles, whelks, clams, prawns and crabs are among the crustaceans that can be found, as well as molluscs like cuttlefish, octopus and squid.
You can put on a pair of sturdy walking boots, pack your lunch, and discover some of the hidden corners of this estuary that swoop right down to the Atlantic.
Enjoy the striking landscapes as you walk the paths or take a trip on a traditional salt galleon out on to the Sado estuary or along the Arrabida coastline.
We invite you spend some of your vacations and holidays time visiting Arrábida Hills.
We invite you to visit Setubal and to visit Portugal
