Thailand is a thoroughly Buddhist country with a rich tradition of meditation, making it an ideal place to rejuvenate your body while refreshing your mind. Some Thai health spas have meditation and yoga classes, while others are simply located in amazing places where you can practice on your own and then head to the spa's treatment rooms for some holistic Eastern or Western therapies. The Kamalaya Wellness Retreat, on the idyllic island of Koh Samui, is a prime example of a cutting-edge spa that offers detox and weight loss treatments as well as meditation programs.
