From the city of Ílhavo, where, besides the Maritime Museum and its Codfish Aquarium, we can observe the aesthetics of Art Nouveau all over the urban building, we head to the codfishers neighborhoods and the Malhada pier. It is thought that it would be here the old Ilhavense seaport. Then we crossed the "Gafanhas", formed by the effect of silting and fertilized initially by the hands of generations of Vaguenses and Mirões, and the National Forest (of the Gafanha Dunes) towards the Mira Channel, branch of the Ria de Aveiro that separates us from the beach of Costa Nova. We head south along the paths of Praião and the Canal, an old agricultural servitude path flanked by "quintinhas", to the east, and fishing, bivalve and seafood harvesting to the west. In Gafanha do Areão we turn towards the Atlantic to the beach with this name - Areão. The final stretch is heading north, now between the Ria and the Atlantic, highlighting the scenic cornfields cultivated on sand and delimited only by the elevation of the dune line. The route from the center of Ílhavo to Praia da Vagueira has a special symbolism... It crosses from the oldest coastal villages, which about ten centuries ago corresponded to the Atlantic front, to the "new" Atlantic front, in lands that were progressively made livable and fertile over the centuries...
