Long Set Beach

Long Set Beach is one of the better-known Koh Rong beaches, though it is more commonly named 4 km Beach. Quieter than its longer neighbour, 7 km Beach, it still boasts a good range of facilities, including several beach bungalow resorts. The main pier and population centre of Koh Rong is just a short walk away, making this one of the more convenient choices on our list. On the downside, the south-eastern view means you miss out on the sunset. However, once the sun has set, the waning moon reveals bio-luminescent plankton, which gives the beach a ghostly glow.
