Koh Khai is a group of famous tiny islands just 15 minutes speedboat ride from Phuket east coast. There are 3 islands: Koh Khai Nai and Koh Khai Nok. Two of them have become pop- ular for their superb sandy beaches and incredibly clear water where a swarm of colourful and friendly fish come to swim around you. 
Such landscape makes incredible photos to take back home, but you must remember that feeding the fish is strictly forbidden: What seems to be an inno- cent gesture or even a nice thing to do for the fish translates into an ecological catastrophe. Worst of all: feeding bread or anything to the hungry fish has be- come illegal, and you could be arrested for it! 

Please note: Water sports are prohibited in the national park. If you would like to take advantage of such opportunities (e.g. water slide), please discuss this with the captain so that he can take you to a place where you can do so undisturbed.
