The Reserva Natural do Sapal de Castro Marim e Vila Real de Santo António, located in the Algarve region of Portugal, spans over 23,000 acres of marshland, saltpans, and estuary landscapes. Established in 1975, this protected area is renowned for its vibrant flora and fauna, including over 200 bird species such as flamingos, storks, and avocets, making it a paradise for ornithologists and wildlife enthusiasts.
