If you like nature tourism, you will love to discover the Natural Reserve of the São Jacinto Dunes. This is a 700 hectares area divided into shifting and fixed dunes which form a wood with mainly Pinus pinaster trees and fresh water ponds. The greatest of these bogs, known as Pateira, is a privileged crossing or wintering sit for migratory water bird species.

As you go through the interpretive trails, you will be able to watch, among others, the great tit, the diving duck, the coal tit, the gull, the tufted duck, the crested tit or the European herring gull. Visit the Welcome Centre and, with a tour guided by the Reserve techniques, you must not miss the chance to discover some of these species in their natural habitat.
