The Spa at Rancho Valencia - Rancho Santa Fe, CA.

If you're going to design a property that includes Bill Gates, President Clinton and Michael Jordan among its elite list of guests, better have a stellar spa to go with it. That's the high bar that The Spa at Rancho Valencia strives to keep for its upper crust clientele. What does that expectation bring? Such amenities as a Watsu therapy/massage pool, rain showers, a Pilates studio and a sparkling new Yoga Pavilion, the byproduct of a recent $20 million renovation.

Spa Highlights: The 2.5-acre spa includes 10 treatment rooms, three therapeutic pools, and couple's rooms with fireplaces and tubs for two.

Most Intriguing Element: The brand new 1,000-square-foot Yoga Pavilion (pictured above) is surrounded by a virtual moat where you can wash away anything you emote amid your deep breaths.
