The largest island off the coast of Sihanoukville is 78km²/48mi². The main harbour, Koh Touch, is crammed with cheap guesthouses, restaurants, diving and water sports centres. It mainly attracts a youthful crowd of night-owls looking to party, but you only have to take a 10-min walk along the white sandy beach to find quieter accommodation. Although actively targeted by real estate developers, for the moment it is still home to postcard-style landscapes, such as the exquisite Lonely Beach.
