Laguna Negra (Black Lake), located in the Rocha Department of Uruguay, is one of the country's largest coastal freshwater lakes, with an area of ​​about 17,500 hectares and a maximum depth of 7 meters. The lake water is dark black, originating from the fragmented peat layer at the bottom of the lake, which reflects less light and forms a unique landscape. There is no connection with the sea here, and it relies entirely on precipitation for water supply. The lake area is listed as a national protected area, with a variety of ecosystems such as wetlands, native forests, meadows and beaches, and is a valuable treasure trove of biodiversity. ​ Tourists can engage in activities such as kayaking, hiking, and bird watching in the lake area, especially at dusk, when the lake is like a mirror, the setting sun is reflected, and the scenery is picturesque. If you love nature and seek tranquility, Laguna Negra is undoubtedly an ideal destination.
