Introduction

Le Parc National Pumalín Douglas Tompkins s'étend sur 402 000 hectares de forêt tempérée valdivienne intacte, de pics volcaniques et de fjords dans le nord de la Patagonie chilienne. Créé à partir de la vision de conservation de Doug et Kris Tompkins, le parc a été donné au Chili en 2018. Dans cette nature sauvage, l'activité géothermique produit des sources chaudes dans certains des cadres les plus spectaculaires et reculés imaginables.

Termas de Cahuelmó

Termas 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.

Temperature: 35-42°C
Tarif d'Entree: $60,000-80,000 CLP per person (includes boat transfer)
Comment y Acceder: Accessible only by boat from Chaitén or Caleta Gonzalo. The boat journey through Cahuelmó Fjord takes about 2-3 hours. Tour operators in Chaitén organize day trips or multi-day excursions.

This is one of the most remote and visually dramatic hot springs in all of Chile.

Temperature: 38-50°C
Tarif d'Entree: Varies by tour operator ($100,000+ CLP for guided expedition)
Comment y Acceder: Located in the remote Porcelana valley, accessible by a multi-hour boat and hiking combination from Chaitén. A guide is essential.
