Canyon Ranch Hotel & Spa in Miami Beach

Miami’s hotel spas trembled at the arrival of Canyon Ranch earlier this year. Here, yogis replace Baywatch-style joggers, and a 70,000-square-foot maze of David Rockwell–designed spaces serves as the backdrop to a host of treatments ranging from mud baths to thalassotherapy. An over-the-top gimmick: “experiential” showers (picture a simulated rainstorm, with the sound and lighting effects to match). Guest rooms offer ocean views and residence-style touches such as granite-clad kitchens—these are condo-hotel rooms, after all—and refrigerators that can be stocked with healthful organic staples upon request.
