This beautiful island off south-eastern Thailand is covered with coconut plantations and circled by (call us clichéd but its true) palm-fringed beaches. It was once an 'untouched' backpackers' mecca, but is now well on its way to becoming a fully-fledged tourist resort. Coconuts are still the mainstay of the local economy, however, and up to two million of them are shipped to Bangkok each month. The most popular beaches are Hat Chaweng and Hat Lamai: both have good swimming and snorkelling but are getting a little crowded. For more peace and quiet, try Mae Nam, Bo Phut and Big Buddha on the northern coast. The main town on the island is Na Thon. Koh Samui's northern neighbour, Koh Pha-Ngan, is more tranquil, and has equally good beaches and fine snorkelling. Its renowned beach parties at Hat Rin are popular with backpackers, though not with the local police. The island is a half-hour boat ride from Koh Samui.
