Phuket

Phuket, Thailand's largest island, is a pretty well-established stop on the tourist trail. But stick around for a few days and you'll find more than flashy resorts and expensive spas. If you want to try your hand at Muay Thai, or you just want to get in shape for the new year at a fitness bootcamp, you'll find plenty of gyms here offering day to month long courses. If you're more of a lover than a fighter, try kite-surfing in Phuket's Chalong Bay during the winter months.
