Wiesbaden Hot Springs Hotel & Spa, Ouray

Wiesbaden Hot Springs Hotel & Spa sits at 625 5th Street in downtown Ouray, Colorado — a short walk from the main street, reached on ordinary paved town streets (sedan access; no high clearance needed). Overnight guests get unlimited use of the outdoor geothermal mineral pool and the vapor cave carved into the mountainside under the lodge; day visitors buy a two-hour soak that covers the outdoor pool and vapor cave. The operator describes chemical-free, continuously flowing mineral water and a vapor cave pool around 106–108°F (about 18 inches deep), with the outdoor pool typically 100–106°F. Capacity is limited to about 15 people at a time to keep the space quiet. Accommodations range from guest rooms with private baths to suites, a hillside cottage, a small historic house on the Historic Register, and a three-bedroom home above the property. Day Soak Passes are never sold online — availability is decided at the front desk from the live count so the outdoor pool and cave stay uncrowded. Massage services and the Lorelei private waterfall pool book separately for every guest, including overnight stays.
