S’Albufera is the largest, most important wetland in the Balearic Islands, a Natural Park that attracts birds and birdwatchers from all over the world. One can move around it on foot or by bike, along four signposted itineraries, and it has observatories and platforms for spying on the numerous winged species that stock up here in winter and autumn, on their journey between Europe and Africa. The marshland configures different ecosystems, inhabited by plants, insects and vertebrates. The abundance of water conditions the growth of the vegetation, which varies depending on the depth, how close it is to the sea and the type of terrain: in flooded areas, reeds, saw-sedge, and bulrushes predominate, and other species grow in brackish areas, such as canes or glasswort. The botanical jewel is the rare and tiny Orchis Robusta orchid.
