Hot Springs: Parque Pumalín
Parque Pumalín Douglas Tompkins, one of Chile's newest and most spectacular national parks, protects vast temperate rainforests and dramatic fjordland. Hidden within its boundaries are some of Patagonia's most extraordinary hot springs, including the legendary boat-access Termas de Cahuelmó.
Introduction
Parque Pumalín Douglas Tompkins National Park stretches across 402,000 hectares of pristine valdivian temperate rainforest, volcanic peaks, and fjords in northern Chilean Patagonia. Created from the conservation vision of Doug and Kris Tompkins, the park was donated to Chile in 2018 and protects one of the planet's most intact temperate rainforest ecosystems. Within this wilderness, geothermal activity produces hot springs in some of the most spectacular and remote settings imaginable. The most famous, Termas de Cahuelmó, can only be reached by boat through a fjord system, making it one of the most adventurous hot spring experiences in South America. The park's hot springs represent the perfect fusion of conservation, adventure, and natural wellness.
Hot Springs
Termas de Cahuelmó
NaturalTermas de Cahuelmó is one of Chile's most extraordinary hot spring experiences. Accessible only by boat through a pristine fjord, the springs emerge on a forested hillside above the water. Natural stone pools at different temperatures are terraced into the slope, with views of the fjord below and snow-capped peaks above. Dolphins often accompany the boat journey. The combination of remote fjord access, primeval forest, and steaming thermal pools creates an experience that feels truly otherworldly.
Termas de Porcelana
WildNamed for the white mineral deposits that resemble porcelain, these wild springs emerge at very high temperatures in a narrow volcanic valley. The milky-white thermal water cascades over white mineral terraces into pools below, creating a visually stunning natural formation. This is one of the most remote and visually dramatic hot springs in all of Chile.
Termas del Volcán Michinmahuida (Park sector)
WildHigh on the volcanic slopes of Michinmahuida, warm springs seep through volcanic rock in a landscape of glaciers, old-growth forest, and towering peaks. These springs are reached only by experienced trekkers on multi-day expeditions. The reward is complete wilderness immersion and thermal bathing in one of the most pristine environments on Earth.
