Koh Samui is an amazing holiday destination. As the second largest island in Thailand, it has an airport that is quickly transferred to all beach locations. One of the best places in Koh Samui is to have the main road that surrounds the entire island, but it is far from the beach. This means you have a bustling shop, restaurants, and bars, but the beach is tree-lined and quiet. This Thai island is 25 kilometers long and 21 kilometers wide, suitable for everyone. Below is an overview of all the major beaches in Koh Samui.
