Southwest Colorado · Ouray, CO
Ouray's quietest historic spa centers on an underground vapor cave, a steamy, mountain-heated grotto that has drawn soakers for well over a century. Day guests get a two-hour soak covering both the cave and the outdoor pool, with admission capped around 15 people to keep it calm. The small hotel upstairs offers lodging and a private reservable Lorelei pool.
For day-use admission, popular resorts sell out on weekends — if the official site offers reservations, book ahead. Weekday visits are usually easier as walk-ins.
Many developed springs welcome families, but age rules, family hours, and adults-only pools vary by property. Check the official site for the current policy before visiting with children.
Start with 15–20 minutes, then cool off and hydrate before going back in. Hot mineral water dehydrates you faster than you expect — drink water between soaks and don't push through dizziness.
