This little beach is home to the rather oddly named Treasure Island Seafood Restaurant, and although not on an island, it's certainly a treasure of a spot, with seafood that many an expat will tell you is the best in Sihanoukville.

The sandy, well shaded beach here is small and secluded, with a few restaurant salas overlooking the water. Stuff yourself on seafood then go for a swim afterwards -- what more could you ask for. Just watch out for the monkeys -- as they won't miss the opportunity to fiddle through your possessions while you're twenty metres offshore.

The beach is named after Ko Pos (Snake Island) which lies just offshore. Ko Pos is best visited from Hawaii Beach, just around the headland from Ko Pos beach, where there are no shortage of boatmen who'll whisk you over there. A trip out to Ko Pos is pleasant enough, but the beaches are nothing too magnificent.
