What's the latest place for a dose of pure pampering?The newly opened 16,000-square-foot Spa at Rancho Valencia Resort (5921 Valencia Circle, Rancho Santa Fe; 800/548-3664;; treatments from $140), located in a bougainvillea-and-hibiscus-filled canyon 25 miles north of San Diego. Designed in partnership with Auberge Resorts, the $12 million facility consists of 10 treatment suites housed in four terra-cotta-and-adobe casitas. Guests can relax over grapefruit-infused raspberry tea and the chef's fresh-baked zucchini bread before heading in for a signature scrub or facial—most of which incorporate just-picked ingredients (avocados, lemons, and tangerines) from the hillside behind the spa. Take some time to sweat it out in the posh fitness room (cardio machines are outfitted with DVD players)—or at least think about doing so as you kick back, banana smoothie in hand, on your treatment room's private outdoor patio.
