Reserva Laguna Negra, Nature reserve in Río Grande, Argentina
Reserva Laguna Negra is a protected natural area in Tierra del Fuego featuring lenga forests, peat bogs, and a dark lagoon with distinct ecosystems. The reserve covers roughly 1200 hectares and contains walking trails that lead through forests and wetlands where visitors can observe native plants and wildlife adapted to the cold southern climate.
The region was home to the Ona people who lived across Tierra del Fuego before European settlement. Later the area experienced forest logging before its ecosystems were protected from further development.
The Ona community 'Rafaela Ishton' maintains their traditions near the reserve, contributing to the preservation of native cultural practices in the region.
Two access points allow visitors to reach the area, with one pedestrian route starting from Hain camping along the lakeshore. Warm weatherproof clothing is essential since conditions remain windy and cool even during warmer months.
The dark lagoon formed through seismic activity and remains separated from a larger lake by a gravel barrier. This geological formation creates two distinct water bodies within the reserve with different environmental conditions.
