Hot Springs, Pray
Concierge.com's insider take:
The same geothermal features that entertain the crowds at Yellowstone's Old Faithful also heat the mineral waters in Chico Hot Springs, a perfect rehab for the body after hiking or skiing. It's located 23 miles south of Livingston at the foot of Paradise Valley's Absaroka Mountains (800-468-9232; www.chicohotsprings.com), and a night under the stars in the open-air springs is a local tradition. Expect rowdy, happy crowds.
