Thanks to its location hidden deep in a residential area of Sukhumvit, the leafy complex of Rasayana Retreat is perfect for those wishing to get away from the hustle and bustle of the city and recharge their batteries with a full-day retreat. Among the menu of holistic treatments, the highlights have to be the detoxification and therapeutic massage options. The one-day package lets you experience both, starting with an infrared sauna session, followed by a salt scrub, detox bath, oil pack, aromatherapy massage and a colonic detox. Your five-hour program is completed with a specially-designed “living foods” meal at the retreat’s raw food cafe.
