About Laguna Negra
Laguna Negra is one of the largest coastal lagoons in Uruguay, with more than 17,000 hectares, and it has no connection to the sea. It is fed by rain and the streams of the region, and its fresh water is of high purity.
The name comes from the color of the water. The bottom is very fragmented peat, and the suspended particles hinder the passage of light, making the lagoon dark. It is also called Laguna de los Difuntos, because indigenous peoples buried their dead in the caves of the nearby hills.
The area is a national park within the Sistema Nacional de Áreas Protegidas. On the shore there are small calm-water beaches between rocks and native forest, and the landscape alternates marshes, fields, and rocky hills. It’s a good place for birdwatching, walking and kayaking.
Because it lies west of Parque de Santa Teresa, the lagoon often has the sunset over the water. Fortaleza de Santa Teresa is about 2 km from the shore.
