Even before the heyday of the adjacent Hotel Colorado, Western notables such as gunslinger Doc Holliday came to take the curative waters of the world's largest outdoor natural mineral springs pool. The smaller pool at Glenwood Hot Springs is 100 feet long and maintained at 104°F. The larger is four times that size, and contains more than a million gallons of constantly filtered water that is completely refilled every six hours and maintained at a soothing 90-93°F. Other
facilities include a children's wading pool, two water slides, a stellar full-service spa, and fitness center.
