If Arizona’s high Sonoran Desert is the “last great treasure in the continental United States,” then the eight-year-old Ritz-Carlton, Dove Mountain is the region’s crown jewel. Its destination spa is an eco-holistic haven utilizing Native American herbs and techniques, and the Jack Nicklaus Signature Golf Course was quickly deemed among the country’s best. Every activity, from tennis and yoga to biking and hiking on 26 miles of trails — not to mention tours to ancient petroglyphs and take-your-breath-away stargazing — is available. Afterward, dine on regional and sustainable dishes at CORE Kitchen and Wine Bar.
