This is the most popular tourist destination on the Western Gulf coast, which isn't surprising, considering Koh Samui's gorgeous beaches, perfect weather, and sparkling blue, almost turquoise, water. Koh Samui has seen rapid development since the 1990s, and you'll encounter hotels in all price ranges.
Koh Samui is half the size of Phuket, so you could easily drive around it in a day. But Koh Samui is best appreciated by those who take a slower, more casual approach. Most people come for the sun and sea, so they head straight to their hotel and rarely venture beyond the beach where they are staying. Every beach has its own unique character, and with a little exploration you may find the one for you.
