The Thai Islands from Bangkok

An hour’s flight from Bangkok, the islands of two seas: on the west, the Andaman, with Phuket, the limestone towers of Phang Nga Bay, Railay and Phi Phi; on the east, the Gulf, with the villas of Koh Samui, Koh Phangan and the dive island of Koh Tao; and close to the capital, Koh Samet and Koh Chang. Here are ten islands, their stories, where to stay, eat and swim, and how to get there.
