Troia Resort

Caldeira

The Caldeira of Tróia is a lagoon which fills up and empties twice a day, unveiling the wetland and muddy bottoms. It forms a recess in the Sado estuary of the Tróia peninsula.

It is an area of great value that provides food and shelter to many species of waterfowl, such as the sanderling, bar-tailed godwit, herons and mergansers, and is thus an excellent site for birdwatching.

Caldeira and the surrounding pine forest are habitats that are a priority in terms of conservation at the European level; consequently, “Sado Estuary” was included in the Natura 2000 network.
