Even on your 12th run, each twist and turn on the five-story waterslide at Fairmont Hot Springs Resort, just west of Butte, Mont., presents a surprise. Enclosed in a tube, you speed through warm spray until you land in a naturally heated pool. On the climb back to the top, take in views of the resort. With a pair of 102-degree soaking pools, not to mention steak dinners and river-rock massages, it offers many opportunities for relaxing after you’ve waterslid all you want.
