For an over-the-top, high-end relaxation immersion, visit the Joya Spa at the Omni Scottsdale Resort. It's in the center of town, right near the iconic Camelback Mountain. You pick an intention stone on your way in, you wander past a 55-pound glowing quartz crystal, and then go to your spa treatment. An ideal treatment for the dry desert is the lemon olive oil body renewal, which ends with you being rubbed down with moisturizing cream.
Then again, with over 50 spas in the area, it can be hard to narrow down to just one. In north Scottsdale, with more of a desert-quiet feel, is the Boulders Resort & Spa. It's got a wide-ranging spa menu that focuses on mind and body treatments like the lotus blossoming chakra massage and the watsu therapy sessions.
