Humedal de Tunquén, Santuario de la Naturaleza de Chile
Humedal de Tunquén is a wetland in the Valparaiso Region fed by freshwater from the Casablanca stream. It spans about 96 hectares with different vegetation types, including woodlands and dry zones near the beach, along with shallow water pools and sandy soils that shift with the seasons.
The wetland was designated a nature sanctuary in 2014 to protect its flora, fauna, and landscape. Archaeological remains show that indigenous communities inhabited and used this area centuries ago.
The name Tunquén reflects the area's coastal heritage. Today the wetland is used mainly as a stop for migratory birds, and visitors come to watch them arrive and depart with the seasons.
Wear comfortable shoes as the ground is soft and sandy, especially after rain or when water levels are high. Simple paths and lookout points allow you to walk along the water without disturbing wildlife.
More than 130 bird species have been recorded here, making it a critical stopover for migratory birds coming from distant countries. This abundance makes each season bring a different mix of visitors to watch.
