Hin Klang reef between Koh Phi Phi Don and Mosquito Island is arguably among the best diving sites outside the Similan Islands. It offers the feeling of swimming inside an aquarium. There are both soft and hard corals and thousands of colorful fish. Tourists visiting the island of Bamboo often visit this dive spot as well. Hin Klang is surrounded by a reef that stretches for about 500 meters to Bamboo Island. It is 90m long and 60m wide. Hin Klang is an accessible location to obtain your advanced diver certifications through diving schools on the nearby Koh Phi Phi Don or Phuket islands. Hin Klang is an excellent place for snorkeling, too.
