Laguna Triángulo is a glacial lake located within Alerce Andino National Park in the Los Lagos Region of Chile. The water body is situated in a mountainous landscape and is primarily accessed via hiking trails, with the most common route being an out-and-back trail from the park entrance. This trail to the lake is approximately 9.5 kilometers one way, and the full hike is typically described as moderate to hard, taking between 3.5 to 6 hours to complete depending on the specific route and conditions. The trail is only accessible during the summer months. The park charges an entry fee, which was noted as 7500 CLP. The lake is the final destination of the hike, suggesting its primary use is for sightseeing, photography, and exploration rather than as a dedicated paddling destination. The surrounding area features other lagoons and trails, such as the path to Lago Chaiguaco and Laguna Chaiquenes. Access involves driving from Puerto Montt south on Route 7, then onto the V-701 road, followed by a 7-kilometer off-road section to reach the trailhead. There is no specific information available regarding direct paddling access points, boat ramps, water temperature, water quality, regulations for boating, or recommended paddling routes on Laguna Triángulo itself.
