Probably one of the most well-known retreat centers in Thailand, The Sanctuary on Koh Phangan is one of those places you’ll find yourself staying for weeks, maybe even months. The longtime favorite offers a range of yoga, detox, weight loss, wellness and spiritual retreats throughout the year along with a world class spa and raved about restaurant. The property’s ‘Tea Temple’ houses a teahouse and cafe (serving healthy teas, shakes, snacks and lunches), library, natural health shop, cinema, lounge and more. If it sounds too good to be true just wait, the gorgeous retreat center is also a beach resort situated right on its own private Haad Tien Beach on the island’s southwest coast. While everything from accommodation to workshops and food at The Sanctuary is top notch, it still maintains a natural, relaxed feel with thatched-roof bungalows, a gorgeous beach setting and emphasis on natural living while being welcoming to all. This may just be paradise…oh, yeah, and the yoga’s good too with daily classes, retreats, intensives, workshops and teacher trainings. If you’re an instructor you can also host your own retreat on the premise.
