Glenwood Hot Springs

Not only is the water here steeped in tradition – Glenwood Hot Springs has been around since 1888 – it also contains 15 minerals credited with making bathers feel (and look) better. The world's largest hot springs pool will relax and rejuvenate you while you stare at the Rockies. And this won't just be a passive soak: The pool has two 300-foot-long water slides.
