This unique environment of the Lower Vouga marshes is quite unique in Europe. The 'Bocage', as it is called, is a mosaic of arable fields separated by hedgerows and narrow irrigation channels. The wide range of biodiversity in the area is due to sustainable farming practice and age-old traditional activities, which have been essential in preserving this natural heritage. The circuit crosses most of the important marine sites.
