We're guessing they don't have a werewolf problem in Koh Phangan, because every month on the full moon, thousands of people take part in the Full Moon Party's all-night festivities, including music on the beach. By day, you'll find a lovely island with coconut trees and plenty of sandy white beaches. If you're a diver, visit Sailrock for a spectacular wall dive.

Drifting serenely in the Gulf of Thailand, the palm-fringed island of Ko Tao takes its name from the abundant sea turtles that reside on its shores. White sand beaches sheltered by steep hills – some only accessible with four-wheel drive vehicles – and 300 days of sun per year invite long afternoons of lounging.

People visit Surat Thani because it's the gateway to so much of Thailand's beauty, especially its Gulf Coast islands. From here, you'll be able to visit Ko Phangan (an island best explored via motorcycle), Ko Samui (known for marvellous beaches and waterfalls) and the 42 rainforest islands of Ang Thong National Marine Park.
