Lago Tepuhueico is a remote and scenic lake nestled within the Parque Tepuhueico on Chiloé Island in Chile's Los Lagos Region, near the municipality of Chonchi. The lake sits within a basin where approximately 94% of the surrounding watershed is blanketed in mature and regenerating native forest — a remarkable ecological setting that includes species such as canelo (Drimys winteri), tepú (Tepualia stipularis), luma blanca, olivillo, avellano, mañío, and coigüe (Nothofagus species). This dense native forest cover contributes to the lake's humic character, giving the water a distinctive dark, tannin-rich quality typical of Patagonian wilderness lakes. The lake is associated with small but ecologically significant wetland areas along its margins. Its wild, largely undisturbed setting makes it a rewarding destination for anglers seeking a true backcountry fishing experience in southern Chile.
