4. Green Valley Spa: fitness on the rocks
Stunning red rock canyons, part of nearby Zion National Park, rim the Green Valley Spa in Utah's high desert. Get moving with a morning hike, then select from more than 100 weekly exercise classes.

Or try an unconventional spa treatment such as a cinnamon-sugar facial or Native American butterfly wrap.

All meals are served family style, with a carb or protein emphasis at breakfast. Lunch is the chef's choice; dinner always offers three selections of vegetarian, fish or fowl and red-meat entrees. Desserts are low in processed sugar, and there is coffee if you desire it, with lots of fruit and vegetables for snacking.

Details Four-night stay includes four spa treatments, all meals, fitness classes and resort facilities; from $2,100, double occupancy. Call (800) 237-1068 (in Utah, call 435-628-8060) or log on to greenvalleyspa.com. --S.R.S.
