The Boulders, Arizona
The wow-factor is left to Mother Nature at The Boulders, and it’s just as well, as no man-made decor could possibly compete with the resort’s surreal 12-million-year-old rock formations. Spanning 1,300 acres of the Sonoran Desert, the massive spa compound promises the ultimate in natural rejuvenation treatments, and the two golf courses are world class. There’s also an über private gated Villa Retreat for celebs seeking anonymity. PR rep Deborah Bridges says, “Our clientele is among the wealthiest in the world, but we’re not allowed to talk about who our VIP guests are until they’re dead.” That says it all.
