Tucked into Kata's most fashionable luxury resort and open to nonguests, this innovative, ubermodern spa blends traditional therapies and organic Ila products with bang-up-to-date technology that includes an antijetlag pod, a temperature-controlled bed and a colour-changing 'chakra room'. Treatments range from Thai massage to bio-energy mud-wraps, couples' oil massages and 'rainforest-rejuvenation' facials. Pricey, but perfect for a special-occasion splurge.
