Four Seasons / The Datai Spa Experience

The two finest spa resorts in Malaysia sit on Langkawi — The Datai, built into primary rainforest above Datai Bay with one of the world's great resort beaches, and Four Seasons Langkawi, a collection of pavilions and beach villas on a mangrove-fringed lagoon. Both offer spa treatments that incorporate local botanical ingredients and jungle settings that make conventional hotel spas seem indoor in comparison.
