Hin Daeng is one of Thailand's best dive sites with the main priority of discovering two fish species that every diver is dying to see: Whalesharks and Manta Rays.

Hin Daeng (Thai for Red Rock) is a huge underwater rocky formation located just over 60 kms from Phi Phi Island. The rock just barely protrudes out of the water by 3 meters but drops steeply back down as deep as 60 meters in some places. Due to its distance from any other land masses, the site is a magnet for fish species both reef and pelagic.

Trevallies and Rainbow Runners patrol the walls, while thousands of glassfish try to seek refuge in the many fissures. Giant morays and yellow edged morays are abundant here. You can't seem to swim for more than a few meters before you find another moray eel.

But then there are the show stealers. Manta Rays often use the ridge to glide along and do barrel rolls, and more often than not the response from the divers is: “I didn't see much else because I was too busy watching into the blue for all the Mantas!"
