Yearning to do nothing? Beautiful Koh Jum, on the western coast of Thailand, is made for unwinding, with nothing more than a handful of secluded beaches, bath-warm water for snorkelling and the occasional low-key bar for drinks with your toes planted in the sand.
If you need a little more activity, cycle the length of the island in around an hour or head to the mountainous north, which has excellent hiking trails, including a route up Koh Pu Mountain.
