Khai Island is a very popular tiny island. It's located approximately 10 km east of Phuket. There are 3 islands: Koh Khai Nai, Khai Nai Island and Koh Khai Nok. Two of them (Koh Khai Nai and Khai Nai Island) have become popular for their superb white sandy beaches and incredibly clear water.
The main draw to Koh Khai is the giant stone arch found on the island. Be aware that visitors may only stay on the island during the day, and must stay on another surrounding island if they plan on sticking around overnight as the island is protected to ensure it's natural beauty remains unspoiled. Khai Island is a great place to stop by for your Phang Nga, Krabi or Phi Phi carter trip.
