Fodor's Expert Review Yampah Spa and Vapor Caves

Part of the Yampah Spa and Salon, the hot springs vapor caves are a series of three underground, geothermal steam baths. Mineral-filled water from a natural hot spring runs about 125°F under the floors of one of the few known natural vapor caves in North America, creating steam temperatures of 110°F–112°F within the rock chambers, where there are marble benches for you to sit on while you inhale the steam. You can take a break in an adjacent cooling room or the upstairs solarium when you need it. Spa treatments are also available, including massages, body wraps, and private mineral baths. Reservations are required and visitors are limited to two hours.
