Río Cruces Natural Sanctuary Adventures

Established in 1981, the Río Cruces Natural Sanctuary is located in the Los Ríos Region of southern Chile near the city of Valdivia. The sanctuary encompasses the wetlands surrounding the Cruces River and its connected water bodies, including lakes and marshes, forming a critical habitat for a wide variety of flora and fauna. This wetland system is internationally recognized under the Ramsar Convention for its ecological importance. Geographically, it consists of freshwater marshes, reed beds, and dense riparian forests that provide essential breeding grounds and feeding areas for numerous bird species. The sanctuary is arguably most famous for the Black-necked Swan population, which thrives in this ecosystem, offering unparalleled wildlife viewing opportunities. In addition to avifauna, the sanctuary shelters various amphibians, fish, and mammals adapted to its aquatic environment. Historically, the area saw reduced human impact compared to other nearby regions, which has allowed natural processes to maintain a relatively pristine state. Visitors to Río Cruces can enjoy birdwatching, photography, hiking on designated trails, and small boat exploration in certain areas. The sanctuary’s proximity to Valdivia makes it accessible for day trips, and the visitor center provides educational resources and guided tours. It is a critical site for environmental education, conservation research, and enjoyment of natural freshwater wetlands in Chile.
