Charlotte Hot Springs sits deep in the San Juan Mountains of southwestern Colorado, requiring a substantial backcountry approach that filters out casual visitors. The springs produce water at around 43°C that forms natural pools above the treeline. The surrounding alpine terrain — with peaks exceeding 4,000 metres and wildflower meadows in summer — creates one of Colorado's most dramatic hot spring settings. Visitors typically combine the soak with multi-day backpacking in the Weminuche Wilderness.
