Tips from the Community
It is possible to visit the lagoon from the north or south shore. In the first case, there are higher observation points, which allow for a wider view, especially at the far end; the second option may be more advantageous on sunny days, as the light will be more favourable. Whichever route you choose, you can follow the path to the beach and start observing the beach inland. On the north side, the best observation point is right at the end of the path – there is a small hill there, which allows a good view of the lagoon and the beach. On the south side, there is a dirt track that ends in a small car park, which also provides easy access to the lagoon. In the lagoon itself, it is common to see mallards, little egrets, grey herons, cormorants and, occasionally, marsh harriers and common terns. During the nesting season, the purple heron is also present – this species often hides among the reeds, making it easier to see when it takes flight. There are other birds that frequent the reeds and, although frequent, are easier to hear than to see – such as the moorhen, the nightingale and, during the nesting season, the reed warbler. The Moinhos stream also attracts some birds that feed in flight, such as the black swift and the sand martin, which are regularly seen here in spring. The surrounding lands are home to several passerines, such as the reed martin, the linnet and the corn bunting. Sometimes, small flocks of waxbills appear. On the beach it is common to see large flocks of seagulls resting, while in the sea gannets can be seen fishing, sometimes at a short distance. The Kentish plover can also be seen regularly on the beach or in the adjacent dunes. Another species that lives in the dunes is the mountain lark. ( avesdeportugal.info )

Near Sines, the mouth of the Moinhos stream forms a small lagoon; this wetland is one of the least known on the Portuguese coast; however, the extensive emergent vegetation makes this place an interesting refuge for water birds.

On the Setúbal coast, there is a haven that seems to have come straight out of a dream: Melides Beach. It stretches along a strip of golden sand that separates the ocean from the lagoon, creating two worlds to choose from: rough seas on one side and calm waters on the other. Even on the busiest days, there is always a quiet corner where you can take a deep breath. Outside of high season, however, it is pure tranquility. And when the sun begins to set, with the waves shining in golden tones, the spectacle is guaranteed.

Melides Beach lies on the long strip of sand that separates the sea from the Melides Lagoon. Deserted in the early season - great.
