nature reserve


The Natural Reserve of the sapal from Castro Marim and Vila Real de Santo Antonio is located in the delta of the Guadiana river and it is one of the most important humid areas of Portugal: it is formed by salty swamps, bodies of brackish water, Salinas, and river arms that host a great number of vegetable and animal species. It is a fundamental habitat for thousand of aquatic birds that find here good conditions to nest and to spend the winter, fully justifying the status given by the Ramsar Convention as a humid area of international importance.

The marshlands are also important as a shelter and reproduction place for numerous fish, mollusks and crustacean species, working as a natural nursery. Beyond the humid zone that covers 65% of the 2089ha of protected area, there are also dry zones that correspond to the hillside of the algarvian mountains with its own vegetable and animal species.
It is therefore in this variety of existing biotypes that consists the wealth of the protected area, as attractive as sensitive to any misconducted human intervention.


Whoever climbs to the castle of Castro Marim, a templar castle that king D. Dinis transformed in the Order of Christ from night to day, keeping the same warrior monks, sees the see on one side and on the other the round shapes of the surrounding hills that reach until the horizon. These are the hills that challenge those who enjoy big open spaces, who are interested in identifying plants and birds, who enjoy walking or cycling, or getting in contact with nature. On the way you will find small villages with low and white houses, surrounded by farming fields, the refreshing spots of the big lakes formed by Odeleite and Beliche dams, the profiles of old windmills on the top of the hills. Then you have the curvy course of Guadiana river, crossing isolated mountains.

The sun is king in Castro Marim’s landscape. It shows itself every day, warms the nature, tans the skin, brings life to the beaches. Altura, Alagoa, Cabeco, Verde and Retur beaches, united by a vast sand plain, are some of the most beautiful in the entire Algarve coast. Surrounded by pine trees and aromatic herbs, are paradises to be discovered. They are laid along a deep blue coast and soft and white sands, that slip between your fingers. With a very temperate climate, these beaches of calm and warm waters, cuddle us to the sound of soft waves.
