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 its beach. But it's worth exploring beyond your lodging. Every beach has its own character, and you might find the perfect one for you. One beach many visitors find to their liking is Chawaeng. On Koh Samui's east coast, this stretch of glistening white sand is divided into two main sections—Chawaeng Yai (yai means "big") and Chawaeng Noi (noi means "little"). You'll find the greatest variety of hotels, restaurants, and bars here. Despite the crowds, Chawaeng is no Pattaya or Patong—the mood is very laid-back. A rocky headland separates Chawaeng Lamai Beach, whose clear water and long stretch of sand were the first place on the island to attract developers. More budget accommodations are available here than in Chawaeng, and there are some happening nightclubs.On the west coast of Koh Samui, Na Thon is the island's primary port and the spot where ferries arrive from the mainland. It's home to the island's governmental offices, including the Tourism Authority of Thailand, and there are banks, foreign-exchange booths, travel agents, shops, restaurants, and cafés by the ferry pier. A few places rent rooms, but there's really no reason to stay here—nicer accommodations can be found a short songthaew ride away.To the north and east of Na Thon lie a few beaches worthy of exploration. Laem Yai, 5 km (3 miles) north, has great seafood. East of here, a small headland separates two low-key communities on the northern shore, Mae Nam and Bophut Beach. Mae Nam is also the departure point for boats bound for Koh Phangan and Koh Tao . Just south of the Samui's northeastern tip you'll find sandy Choengmon Beach, a good area for swimming that's not overdeveloped.
