The Most Beautiful Hot Springs & Geothermal Wonders
10 places · every one real, mapped, and worth the trip
Where the Earth's heat meets the surface, water paints the land — depositing snow-white travertine, staining pools electric blue and orange with heat-loving microbes, and firing geysers into the sky. These are landscapes made by chemistry as much as by rock.
This is our editors' pick of the most beautiful hot springs and geothermal wonders on Earth. It isn't a ranked countdown, but each is a real, mapped place with an honest guide to reaching it — and a note on which pools you can actually bathe in and which are protected.
-
Pamukkale The cotton castle
Denizli Province, southwestern Turkey
A hillside of dazzling white travertine terraces in Turkey, filled with warm turquoise water and stepping down beside the Roman ruins of Hierapolis.
-
Yellowstone Rainbow pools
Wyoming / Montana / Idaho, United States
The greatest concentration of geysers on Earth, plus hot springs like the Grand Prismatic ringed in blue, green, and burning orange.
-
Huanglong
Sichuan Province, China
A valley of tiered travertine pools in Sichuan, China, terraced in gold and turquoise like a staircase of natural mirrors beneath snow peaks.
-
Badab-e Surt
Mazandaran Province, northern Iran
Rust-red and cream travertine terraces in northern Iran, coloured by iron-rich springs and glowing warm at sunset.
-
Geysir & Strokkur
Haukadalur geothermal field, Southwest Iceland
The Icelandic field that gave the world the word 'geyser' — Strokkur erupts a column of water every few minutes above steaming ground.
-

Bay of Plenty, North Island, New Zealand
A whole town of steaming vents, bubbling mud pools, and vivid mineral terraces in New Zealand, at the heart of Māori geothermal culture.
-
Danakil Depression
Afar Region, northeastern Ethiopia
One of the hottest, lowest places on Earth in Ethiopia, where acid springs and sulphur crusts paint the ground neon yellow and green.
-
Hierve el Agua
San Lorenzo Albarradas, Oaxaca, Mexico
A 'petrified waterfall' in Oaxaca, Mexico — mineral springs that have built a frozen cascade of white rock above spring-fed pools.
-
Ma'in Hot Springs
Between Madaba and the Dead Sea, Madaba Governorate, Jordan
Hot waterfalls tumbling down a desert gorge in Jordan near the Dead Sea, heated by the same rift that split the valley.
-
Jigokudani & the Snow Monkeys The snow monkeys
Yamanouchi, Nagano Prefecture, Japan
A steaming hot-spring valley in the Japanese Alps where wild snow monkeys bathe in a natural thermal pool through the winter — the only place on Earth they do.
Geothermal wonders demand respect: many of these pools are protected or scalding, and the safe ones for bathing are noted in each guide. Cooler, clearer months and low light bring out the colours best — and steam is most dramatic in cold air. Each guide notes the season and the rules.
