Laguna de Castillos, body of water
Laguna de Castillos is a lagoon in Rocha Department covering about 8,000 hectares and connected to the Atlantic Ocean through Arroyo Valizas. The site features wetlands, reed beds, ombú forests (a native tree with the largest concentration in the region), palm groves, and open grasslands, creating a varied landscape.
The lagoon was declared a wildlife refuge in 1966 to protect species and habitats in the area. Since 1981, it has been recognized as a Ramsar site of international importance and is being integrated into Uruguay's national protected area system.
The lagoon takes its name from the nearby town of Castillos. Today, visitors come here to watch birds, take walks, and explore nature, while local communities work in conservation and tourism activities connected to this place.
The site is about 15 kilometers south of Castillos town and offers walking trails, boat trips, bird watching, and guided tours with local guides. Visitors should know that hunting, camping, and open fires are prohibited to protect wildlife.
The Arroyo Valizas, the waterway connecting the lagoon to the sea, naturally opens and closes through sand bars, constantly changing the water's salinity and clarity. This dynamic connection creates a rare transition habitat where over 256 bird species take shelter, making the region a special place for natural observation.
