- Ria Formosa Natural Park
On barrier islands near Faro are some beautiful remote Algarve beaches, easily reached via regular ferries from Faro's ferry pier. The ferry trip to the Blue Flag Ilha da Barreta beach takes around 20 minutes, and it's a great trip for Algarve bird watching, as the boat crosses sand and mud banks. Here one finds flamingos, sandwich terns, plovers, common terns, little terns and gull-billed terns.
-Sapal de Castro Marim
The wetlands of the River Guadiana, between Castro Marim and Vila Real de Santo António, feature meadows and marshes. This Marshland Nature Reserve of Castro Marim and Vila Real de Santo António was the third zone to be declared a Nature Reserve in Portugal. Native birds include the stork, flamingo and the black-winged stilt that is the most common species in the zone and was therefore chosen as the symbol of the Nature Reserve. On foot or by bicycle, the trails lead us to the salt pans that occupy around one third of the protected area, and which for many centuries constituted the main source of riches in the region. Salt continues to be produced in many of the salt pans, in accordance with artisan processes, delivering a product whose quality is certified by the Nature Reserve.
