Koh Hu Chang is a very small island that, although quite shallow at around 10 meters, has some very good corals and abundant small fish life.
Koh Hu Chang has more sea anemones than either Koh Rin or Koh Man Wichai and as it is well protected from the wind is a good relaxing dive spot.
Koh Klung Bedan is another small dive site that is also quite shallow, maximum coral depth being 12 meters.
This dive site has many Staghorn and Table corals as well as Boulder corals that have many Christmas Tree worms.
