This equipment is part of the Network of Nature Observatories and is an integral part of a roadmap, which also includes pedestrian trails, that show the most interesting places for leisure and bird watching. Built in wood, it faces the estuary of the Cávado river and has seats allowing birdwatchers as well as hikers a pleasant place to rest and enjoy the landscape.
Classified as a protected area, the Cávado estuary is characterized by the uniqueness of its reeds and Atlantic salty meadows. Its ecological relevance is based on the nutrient loads brought into the estuarine waters that constantly flood it and the high biological productivity indexes of its marshes and mudflats uncovered at low tide, so favorable for the occurrence of avifauna.
Located in an important migratory corridor for birds, this wetland is, therefore, a habitual stopping place or wintering destination for many species that find here a mild climate and a diversity of wide natural habitats that guarantee their sustenance and the necessary conditions for rest and protection. Here proliferate mainly waterfowl species, such as herons, ducks and cormorants, or waders, such as sandpipers and ruddy turnstones that occupy this marginal.
Located in Ofir - Fão, it is easily accessible through smooth and comfortable walkways.
