Description: Across the sea from Sihanoukville in Cambodia sits Koh Rong Island. Featuring 43 kilometers of white-sand beaches, untouched jungle and turquoise-clear water, the place resembles a paradise. Because of its tranquility and its distance from the mainland, the island is a great venue to enjoy scuba diving as well as snorkeling, hiking, mountain biking and kayaking.
