Cambodia's south coast has more than 60 pristine tropical islands nestling in the sapphire waters of the Gulf of Thailand. Easily reached from the coastal centres of Sihanoukville, Kep and Koh Kong, they're largely undiscovered with tourism taking its first tentative steps. If you stick to the local or small ex-pat run concerns, the Cambodian islands offer everything from palm fringed deserted beaches, traditional village life to the peaceful beach shack living found in Thailand 20 years ago. If you want to be literally the only person on the beach, then head to Koh Rong. Two-and-a-half hours by boat from Sihanoukville, it's arguably the most magnificent island off the coast. Dumbbell shaped with a dense jungle interior, Koh Rong is a pristine island rarely visited by other travellers. The beach on the southwest side is known as "Snowdrift Bay" and for good reason, its talcum-soft sand squeaks under foot and goes on for miles. There's no path to it, however, so get dropped off there or charter a boat from the fishing village where there's a shop to stock up on supplies.
