EXPLORE BY REGION
Plan Your Visit
Every season transforms the hot spring experience. Here's where to go — and what to expect — throughout the year.
"Steam rising against snow — the ultimate contrast soak"
Winter is prime soaking season. Snow-dusted mountains, frozen air, and steaming mineral pools create an experience unlike any other time of year. Many resorts offer their best ambiance — and thinner crowds — between December and February.
Chena Hot Springs
Fairbanks, AK · 100–106°F
Soak under the Aurora Borealis — the only hot spring in the US where you can reliably see the Northern Lights from the water.
Strawberry Park
Steamboat Springs, CO · 75–106°F
Snow-covered forest, candlelit pools at night, and a strict adults-only policy after dark make this Colorado's most magical winter soak.
Ouray Hot Springs
Ouray, CO · 80–106°F
Surrounded by 13,000-ft peaks and ice-climbing routes — the 'Switzerland of America' is stunning in winter.
Thermopolis State Park
Thermopolis, WY · 104–135°F
Free soaking year-round at the world's largest mineral hot spring — no crowds in January.
