World's Coolest Hot Springs

Banff Upper Hot Springs, Alberta, Canada
The Soak: What’s a little pungent aroma when you’re surrounded by the majesty of some of North America’s most awe-inspiring peaks—including aptly named Sulphur Mountain? Discovered in 1884, these soothing 98°F–104°F waters are loaded not only with sulphate but also with calcium, magnesium, sodium, and bicarbonate.
The Scene: Set amid the glacier-studded panoramas of Banff National Park, the spring-fed pools are serviced by a retro-rustic 1930s bathhouse with splendid views of Mount Rundle. Hike the steep 3.5-mile switchback trail up Sulphur Mountain before a pre-sundown soak.
When to Go: Year-round, but for fewer crowds and peak foliage visit in the morning during early fall.
