Chile sits on the Pacific Ring of Fire — volcanoes run the length of the country, and where there are volcanoes there is geothermal activity. Hot springs (termas) range from developed resort complexes with multiple pools and spa treatments to unmarked natural pools in remote valleys where you share the water with no one.

Central Chile

Baños Colina (Cajon del Maipo) — Terraced natural pools at 2,600 meters in the Andes above Santiago. Volcanic terrain, steaming water, and mountain views in every direction. The road requires a 4WD vehicle. Open roughly October through April. About 2.5 hours from Santiago. No facilities beyond the pools.

Baños Morales (Cajon del Maipo) — Lower and more accessible than Colina, at 1,850 meters. Simple stone pools in a small mountain village. Basic accommodation and food available in the village. About 2 hours from Santiago with a high-clearance vehicle.

Lake District

Termas Geometricas (near Pucon) — The most beautiful hot springs in Chile. Seventeen slate-lined pools connected by a red-painted wooden walkway through a narrow canyon draped in ferns and native forest. Hot waterfalls cascade between pools of varying temperatures. About an hour south of Pucon. Entry around $30. Worth every peso.

Termas de Huife (near Pucon) — Three outdoor pools at different temperatures in a forested setting, about 30 minutes from Pucon. More developed than Geometricas with changing rooms, a restaurant, and massage services. Less dramatic but more comfortable.

Termas de Pucon — The closest hot springs to Pucon town, walking distance from the center. Resort-style with multiple pools, a cold plunge, and a spa. Convenient but lacks the wild setting of the other options.

Puyehue Hot Springs (near Osorno) — A large thermal complex inside Puyehue National Park. Indoor and outdoor pools, mud baths, and forest trails that start from the hotel. The setting in old-growth rainforest is exceptional. Can be combined with a visit to the Antillanca ski resort in winter.

Termas de Chillan (near Nevados de Chillan) — Combines hot springs with skiing in winter. Outdoor pools surrounded by araucaria (monkey puzzle) trees. The resort operates year-round — ski in the morning, soak in the afternoon.

Atacama

Puritama Hot Springs (near San Pedro de Atacama) — Eight pools carved into a desert canyon at 3,500 meters, connected by wooden walkways. The contrast of hot water against cold desert air is striking. About 30 minutes from San Pedro. Entrance around $15. Go in the afternoon when the sun warms the canyon walls.

Patagonia

Termas del Amarillo (Pumalin Park, Carretera Austral) — Simple hot pools in the rainforest, managed by the Tompkins Conservation foundation. Basic but atmospheric — surrounded by giant nalca leaves and dripping moss. Low cost, no luxury, pure nature.

Tips

  • Bring your own towel — most natural springs do not provide them.
  • Weekdays are dramatically quieter than weekends at all springs within day-trip range of Santiago or Pucon.
  • The best experiences are often the least developed. A natural pool with no facilities and no other visitors beats a resort pool every time.
  • Check seasonal access — highland springs (Colina, Puritama) close in winter when roads become impassable.
