Koh Rong, also known as Monkey Island, is a blissful breath of sea air after travelling some of Cambodia’s more rough and rugged inland destinations. This little island, situated 25km off the coast of Sihanoukville, has 43km of exquisite sand beaches lining the east and west coasts, lapped by temperate turquoise waters. The interior is largely covered with rainforests where you can go hiking along beautiful trails. Koh Rong is still a relatively under the radar destination, with just a handful of accommodation options and entertainment venues, although there is good nightlife to be had at Tui Bay.
