The setting for the Leonardo DiCaprio film The Beach, Maya Bay is all about its crystal clear water, powdery white sand and lush greenery. The best way to visit is on an organised tour around the Phi Phi Islands. Maya Bay can only be accessed by boat and at times even that's a struggle, as hordes of tourists are ferried in to admire the beauty of this "secluded" bay. Visit out of season and the numbers dwindle, leaving an almost deserted, white sandy beach and bright blue water teeming with coral life. If you opt for a tour, snorkelling equipment is normally provided and included in the price. Some of the most beautiful sights here are actually to be found underwater. Maya Bay has become entwined in controversy in recent years as local authorities and environmentalists have attacked film-makers for meddling with the natural beauty of the bay for the production of The Beach.
