The wild horses that still roam the Gila River Indian Reservation near Phoenix get new neighbors this month — 500 rooms’ worth. The SHERATON WILD HORSE PASS RESORT & SPA joins the equines of the high Sonoran on 372,000 acres. Developed by the native Pima and Maricopa tribes, the sprawling oasis boasts four pools, two manicured 18-hole golf courses, and a 17,500-square-foot spa touting watsu therapy and a meditation roundhouse. Make dinner reservations at chef Janos Wilder’s new resort outpost Kai before saddling up a horse — one tamed, that is — for a sunset ride. From $149. (800) 325-3535,
