 Located on the Andaman coast just south of Koh Lanta, Koh Hai is a great island for a day trip from Krabi or Trang for the diving and beautiful scenery. A lot of the divers who come here are on such trips mainly from Koh Lanta. 

The islands spectacular mountain landscape continues below the surface providing divers with spectacular topography and many interesting features such as caves, overhangs, swimthroughs and sheer walls covered in pretty corals. As well as this excellent back drop the area provides a range of marine life from the usual reef life of the Andaman sea such as nudibranches, anemone fish, moray eels and other reef fish to the larger nurse and leopard sharks. The landscape of overhangs, caves and swimthroughs provide a perfect environment for these bottom dwelling sharks.
