Koh Tao ('Turtle Island') has been described as offering 'heaven under the sea', its main attraction being the incredible snorkelling and scuba diving opportunities afforded in its clean, clear waters. Situated to the north of its more famous sisters, Koh Samui and Koh Pha Ngan, the island is a typical tropical paradise, with rich jungle in the centre surrounded by quiet, palm treed beaches. Although tourist development has exploded in recent years, turning the traditional dirt-road villages into a montage of resorts, souvenir stalls and restaurants, there are still plenty of unspoilt spots both on the coast and inland. The main beach is Sairee Beach, stretching about one mile (2km) along the west coast, offering a range of reasonably-priced accommodation, dive centres, restaurants, beach bars and other facilities.
