The 10 Best Hot Springs in Colorado
Colorado soaks harder than any state but Idaho: two-block-long resort pools, stone terraces above Steamboat, free river pools rebuilt every summer, and a backcountry pool at 11,200 feet that requires a permit and a 17-mile round trip. Every fee, road rule, and reservation below was checked against current sources.
Know each spring's personality before you drive — one is clothing-optional by policy, one bans it, one requires 4WD by county law all winter, and one won't let you in at all without a room.
