Waihua Spa, Ritz-Carlton, Kapalua
At this gorgeous 17,500-square-foot spa, you enter a blissful maze where floor-to-ceiling riverbed stones lead to serene treatment rooms, couples' hales (cabanas), and a rain forest-like grotto with a Jacuzzi, dry cedar sauna, and eucalyptus steam rooms. Hang out in the co-ed waiting area, where sliding-glass doors open to a whirlpool overlooking a taro patch garden. Exfoliate any rough spots with a pineapple-papaya or coffee scrub; then wash off in a private outdoor shower garden before indulging in a lomilomi massage (traditional Hawaiian massage involving powerful strokes down the length of the body). High-end beauty treatments include advanced oxygen technology to tighten and nourish mature skin. The boutique has a well-curated display of organic, local, and high-end beauty products, fitness wear, and Maui-made jewelry. www.ritzcarlton.com.
