Hat Sai Kaew or Diamond Beach is the longest and one of the most popular beaches on Ko Samet. It is located in the north-east and it is about 780 meters long. This is the beach you should choose if you do not want that many people and activities around you, but at the same time live next to a almost paradise-like beach. The sand is almost snow-white and the water is invitingly green-blue. You will find a number of cozy restaurants and bars here too, as well as good accommodation. Along the beach you find many bungalows and hotel rooms for rent. Here you also find many different activities if you don't only want to sunbath. A few examples: windsurfing, jet ski, snorkeling, ride a bananboat and later in the evening, have a cocktail or long drink on the beach.
