Baños Termales de Monterrey (Huaraz)

Baños Termales de Monterrey is a celebrated natural hot spring complex 7 kilometres north of Huaraz in the Ancash Region of Peru, where ferruginous-sulfate mineral waters emerge in the Callejón de Huaylas valley at the base of the Cordillera Blanca — the world's highest tropical mountain range and the site of Peru's most comprehensive high-altitude trekking network centred on Huascarán National Park, a UNESCO World Heritage Site. The springs, operating as a popular thermal bathing facility since the early 20th century within a long thermal tradition, provide a warm mineral bathing complement to the cold and demanding mountain environment of the Cordillera Blanca's glaciated peaks, turquoise lagoons, and high-altitude trekking routes. The Monterrey springs have been a fixture of Huaraz's adventurer culture for generations, offering trekkers and mountaineers — many returning from multiday expeditions on iconic routes like the Santa Cruz Trek or attempts on Nevado Huascarán (6,768 m) — the deeply satisfying reward of hot mineral bathing in a spectacular Andean valley.
