Otres Beach in Sihanoukville has been the big winner in recent years thanks to a bit more tranquility, some more relaxed music and the much better swimming.
Also less commercial activities speak for the currently perhaps prettiest beach in the area, which offers a variety of nice looking hangouts and restaurants.
Happy hours and 50c beers have also found their way to the more relaxed and chilled venues that are even renting out some basic beach cottages for around $15 per night.
The water is fairly shallow close to the beach so that some nice temperatures tange from warm to fresh depending on the season, so that also kids and less experienced swimmers will feel absolutely safe and comfortable.
