Lago Lolog
Tucked into the southern arm of Lanín National Park in Argentina's Neuquén province, Lago Lolog is a glacial lake of strikingly clear water, ringed by dense Andean-Patagonian forest of coihue and lenga. Set at about 900 meters and spreading across roughly 35 square kilometers, it occupies a valley that cuts perpendicular to the Andes — a long, green basin that feels remote despite sitting only a few kilometers from the ski town of San Martín de los Andes. The name comes from mapudungun, the language of the region's Mapuche people, meaning "cave" or "hole" — a nod to the deep, shadowed pockets of the lake. Today Lolog is one of the most complete circuits in the park: broad open beaches, forest trails and viewpoints, a handful of campsites, and easy water access make it a favorite both for day-trippers and for anglers who come specifically for the trout.
