Koh Rong Samloem is and island off the coast of Sihanoukville in Cambodia, with a a paradise white beach and turqoise water. Definitely worth a visit!
I took the party boat (not really a party) from Sihanoukville to Koh Rong Samloem island. The water was white, the water was blue and so so warm! The party boat costs $20, although I got a discount to $18. With that you get the return boat ride, a pastry for breakfast, free tea and coffee, one ticket for a free drink, lunch and access to snorkels if you want to go snorkelling. There is music on the boat and the top deck has a massive area for sunbathing.
