When this now-venerable resort opened in 1979, “wellness” was widely considered a California oddity, spas were crusty old resorts in Europe, and massages were indulgences for the rich. The fact that perspectives have changed on all these aspects of vacations is partly due to the reputation grown by this seminal spa. But it’s not just for Pilates and aromatherapy: The 200-acre lower-foothills property is laced with hiking trails; there are three outdoor pools; an indoor aquatic center; seven tennis courts; about 50 daily classes and activities; lavish fitness facilities and lovely desert landscaping throughout the grounds, not to mention a Golf Performance Center. The resort’s lavish 80,000-square-foot spa facility is vaguely reminiscent of a Roman bath, and guests stay in single-story Southwestern bungalows whose décor features desert colors (sage and sand), leather furniture and outdoor patios. Sabino Canyon is nearby, and guests receive free shuttle transportation from Tucson airport.
