Sihanoukville, also locally known as Kompong Som, is Cambodia’s leading beach resort. There are empty white-sand beaches around the headland, unspoiled islands off the coast and the popular Kbal Chhay waterfall near town. As well as relaxing on the beach, boat trips to Koh Russei, Koh Rong and other islands are a popular activity. Snorkeling and diving can also be arranged, although the best diving lies quite a long way offshore and would require an overnight stay on a boat or island. The best beaches are Occheuteal and Otres Beaches, but large parts of under redevelopment. For something more remote or romantic, try and the beaches of Ream National Park or one of the offshore islands. Ream National Park, just 15km from Sihanoukville, is a coastal park occupying 21,000 hectares, including two islands, Koh Thmei, and Koh Ses.
