Laguna Larga is a lake located near Lago del Desierto in the province of Santa Cruz, Argentina, approximately 37 kilometers from the town of El Chaltén. The lake is situated in a remote, forested area near the border with Chile and is part of a trekking route rather than a primary paddling destination. The primary access point for visiting the area is via a boat service that navigates Lago del Desierto, connecting Punta Sur to Punta Norte. From Punta Norte, a trail begins behind the National Gendarmerie post and leads through a dense, quiet Lenga forest, skirting the shores of Laguna Larga. The trail includes basic tree trunk bridges over a small stream feeding the lagoon. The overall character of the area is one of significant isolation and natural beauty, with the trail offering spectacular views of the full expanse of Lago del Desierto, the Del Bosque range to the east, and the Vespignani range with its hanging glaciers to the west. The Fitz Roy massif is also visible from the northern perspectives along the route. The trek is considered a moderate, full-day activity typically undertaken during the high season when boat schedules permit, with treks starting around 10:00 a.m. and requiring a return to the boat by 5:30 p.m. The terrain includes an initial ascent, muddy sections known as "mallines" that require detouring, and a generally quiet, little-visited forest. There is no specific information regarding direct paddling on Laguna Larga itself, such as put-in points, water temperatures, regulations, or recommended routes for kayaks or paddle boards. A separate Laguna Larga Lodge associated with Los Alerces National Park offers guided kayak crossings on the park's lakes, but this appears to be a distinct operation in a different region of Argentina and not directly related to the Laguna Larga near El Chaltén.
