Located in the Rocha department of Uruguay, Laguna de Castillos Nature Reserve is a coastal lagoon and wetland complex that plays a crucial role in regional biodiversity conservation. This protected area encompasses a mix of freshwater and brackish environments, lagoons, marshes, and adjacent grasslands, creating a mosaic of habitats ideal for numerous species. The reserve is internationally recognized as a Ramsar wetland and is part of the Uruguayan Coastal Biosphere Reserve, highlighting its ecological significance. It serves as an important stopover and breeding site for a diverse array of migratory and resident bird species, including flamingos, herons, ibis, and various waterfowl. Besides avian life, the reserve supports amphibians, fish, and mammals adapted to wetland conditions. Visitors appreciate the reserve not only for its rich wildlife but also for its tranquil setting offering hiking and nature walks on designated trails and birdwatching platforms.
