Footpaths in Lagoa de Óbidos
In search of mallards - This itinerary covers an area of great beauty, revealing the most guarded and richest landscaping of Óbidos Lagoon.Exit Óbidos towards the Lagoon and, approaching it, drive through part of a fitness circuit semi-abandoned, then going to the first bird observation tower near Braço da Barrosa, where Cal river empties. With the precious help of binoculars we can see some "royal" birds such as heron, duck and torch, along with the less 'noble' as the black-winged stilt, the cowboy-heron, the little egret and the herring gull. This quite corner of the lagoon is a nesting area. Continuing towards the second tower, walk the dirt road coming from the wastewater treatment plant, the trail unfolding by the water (if you brought a snack, you can have it at the picnic area). Having filled your batteries, go down to the wooden bridge, to begin the climb towards the mentioned second tower. Here we can see, from afar, the secular fishing of shellfish and eels that remains the major source of livelihood of the community of 'shellfish catchers', “mariscadores” . Having completed this main route, you can venture out to a second walk of 1 km in length, called the path of the Stork's Nest, "percurso do Ninho da Cegonha".
Leave Óbidos again, but taking the road to the ancient Roman city of Eburobrittium. The route can be assessed in the floodplains of Paul and Cegonha with its extensive agricultural fields and where the fruit and cereal crops are the predominant activities; the Arnóia River with the specific local fauna and flora of this natural habitat; the Mãe de Água Quente, consisting of three springs of sulphurous waters with medicinal properties and, finally, Eburobrittium, where you can see vestiges of the Roman presence, from the first to the fourth centuries.
