The Río Yendegaia flows through the remote and pristine landscapes of Yendegaia National Park in the Chilean region of Tierra del Fuego. This river system is set within a vast, mountainous national park encompassing over 150,000 hectares of protected wilderness. The area is characterized by its significant conservation value and hosts a variety of native birdlife, including Upland Goose, Austral Parakeet, and Austral Thrush, indicative of a healthy riparian ecosystem. As a waterway within a Chilean national park, its management and public access are governed by national recreational fishing laws.
