Sagestone Spa & Salon

Red Mountain Spa has added 12 residential villas (from $540,000) to its 55-acre crimson desert setting for those who find a week of pampering is just not enough. Owners get access to the resort's full range of amenities, from programs (new this year: tai chi on the rocks) to the dining room's healthy food, and — of course — the spa's 62 treatments.
