The Spa at the Four Seasons Westlake Village

If 40,000-square feet of 28 treatment rooms, each with a private terrace, four luxury suites decked out with private plunge pool, day bed and whirlpool don't wow, then the fully-equipped, holistic wellness program is sure to impress spa snobs and feel-good gurus. The only-of-its-kind California Health & Longevity Institute is a one-stop-shop med-spa: Get your teeth whitened and skin tightened and peeled the same day your chi is unblocked with acupuncture and energy healing. For those in need of a diet overhaul, nutritionists and dietitians are on-hand as well as a Wellness Kitchen to school you on DIY clean eating. The East-meets-West theme continues with a Chinese footbridge and bamboo floors throughout the spa and a towering pagoda in the meditation garden. Couples and groups up to ten can pamper themsleves in one of the four luxury spa suites complete with a private patio, plunge pool and whirlpool tubs or rent an enclosed, poolside cabana where a light fare menu of smoothies, salads and wraps can be served. Unwind (and splurge) on signature body treatments—we love the Westlake Signature Treatment ($330, 100 minutes), inspired by a Balinese, pre-wedding ritual that involves a foot bath, tumeric body scrub and coconut cream massage—and space age-y facials from Anti-Gravity ($250-$2,000) to DNA Growth ($175-$245).
