Glenwood Springs

Glenwood Springs needs 1 day: touring Glenwood Caverns Adventure Park, the only mountaintop theme park in the United States, with roller coasters and a gondola climbing over 2,100 meters to explore underground caves, and soaking in Glenwood Hot Springs, the world's largest hot springs pool, the same afternoon. June-September brings the best weather for outdoor activities. It's mid-to-upper priced given its mountain spa town profile. Its hot springs were considered sacred by the Ute people long before they were visited by gunslinger Doc Holliday, who died and is buried in the town in 1887 while seeking relief for his tuberculosis in the same waters.
