Koh Racha Noi Island is two hours away from Phuket island by a day trip boat, and well worth the journey. This is the best island if you are interested in seeing the large schools of fish as well as sharks and manta rays.

At Koh Racha Noi you have the best chance of all dive sites to encounter the magical manta rays which will grow to an impressive 6 meter span. Also keep an eye out in the blue for the white tip and black tip reef sharks. These are the quietest dive sites in the Phuket area due mainly to the distance from the port, so normally it will only be our day trip boat on the island for the day.
