Hot Springs: Junín de los Andes
Junín de los Andes, Argentina's trout fishing capital, is the gateway to Lanín National Park where volcanic activity from Lanín Volcano creates natural hot springs in pristine wilderness settings among araucaria forests and glacial lakes.
Introduction
Junín de los Andes sits at the base of Lanín Volcano in Neuquén province, surrounded by the stunning landscapes of Lanín National Park. While the town is primarily known as one of the world's premier fly-fishing destinations, the volcanic geology beneath the Andes also produces thermal springs that attract visitors seeking relaxation in nature. The hot springs accessible from Junín are mostly within the national park, set among ancient araucaria forests, pristine lakes, and volcanic landscapes. They tend to be more natural and less developed than those near neighboring San Martín de los Andes, appealing to visitors who prefer a wilder, more authentic thermal experience.
Hot Springs
Termas de Epulafquen
NaturalNatural thermal springs near the shores of Lago Epulafquen, where warm mineral water emerges among rocks in a forested setting. Informal stone pools have been shaped by visitors over the years. The setting within Lanín National Park, with views of volcanic peaks and araucaria forests, makes this one of the most scenic hot spring locations in Neuquén province.
Termas del Lahuen Co
ResortWhile technically closer to San Martín de los Andes, Lahuen Co is a popular day trip from Junín. This modern thermal complex offers multiple pools at varying temperatures with mountain views, plus a full spa with professional treatments. It provides the most comfortable hot spring experience accessible from Junín.
Termas de Huechulafquen
WildWarm water seepages along the volcanic lakeshore of Lago Huechulafquen create subtle thermal pools. The temperatures are mild and the springs are modest, but the location on one of Patagonia's most beautiful lakes with Lanín Volcano reflected in the water makes any visit worthwhile. Combine with fishing or lake activities.
