Koh Samet is a typical tropical island with beautiful white sand and blue sky. It is the closest beach paradise which is 4 hours away from Bangkok. It could be an ideal island for a person who do not have time but want to see a coral island.
The beach of Ao Kiew on the picture is located at the South tip of the island. The sand is white and the beach is very quiet.
