Sihanoukville (also known as Kompong Som) is Cambodia's only port. It's currently being redeveloped as a tourist attraction, with a casino planned for Naga Island. At present Sihanoukville's chief attraction is the great snorkelling and diving that can be found around the nearby islands - some of the guest houses in town can arrange a boat trip for you. The best of the beaches around the town is probably Ochatial Beach, although its worth riding a bike down to Independence Beach, where you can check out the allegedly-haunted Independence Hotel.
Tender Port - Wheelchair access limited and some mobility may be required to board tenders.
