AT A GLANCE
Why go?
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.↗↗
A world-class trout fishery
Lago Lolog has earned a near-mythical status among anglers in Argentina's Lake District. The lake is stocked with rainbow, brown and brook trout, with average fish running a satisfying 38–50 cm and the occasional monster pushing past 60 cm. A skilled day on the water can yield a true "grand slam" — rainbow, brown and the more elusive, cold-loving brook trout all caught in the same waters.
