I really liked the beach, the sand is really white and very soft and shallow. It is convenient to swim, especially with children, with a gentle entrance to the water. There are many restaurants by the water in the evening.
White Sand Beach on Chang Island is (subjectively) the best for us. However, we were not everywhere - White Sand, Klong Prao and Kai Bay. I also like Klong Prao, but there is fine gray sand, it is lifted by waves and the water becomes cloudy. On White Sand, the yellow sand is bigger, it is not so muddied by the wave. On Kai Bay this year, on the first day of vacation, my daughter and I were injured by sea urchins, so we are unlikely to choose this beach again for recreation. A lot of hedgehogs were found on the shore in the evenings when they walked later.
