In the Maldives, there's water, water everywhere, and three just-opened spas at private-island resorts make the most of it. Even lying on a massage table, you're never far from the Indian Ocean at the 44-room Soneva Gili Resort & Spa (800/525-4800 or 960/440-304; doubles from $500)—their Six Senses Spa is built over a shallow lagoon. The 45-villa Angsana Resort & Spa Maldives, Ihuru (960/445-502; doubles from $310) focuses on modern versions of ancient Ayurvedic treatments, like an appetizing watermelon-honey facial. The Island Spa at Four Seasons Resort Maldives at Kuda Huraa (800/332-3442 or 960/444-888; doubles from $400) is the ultimate castaway experience—it's accessible only by a wooden dhoni (a Maldivian fishing boat).
