Great Scuba Diving at Shark Island Koh Tao
Shark Island gets its name due to the shape of the island resembling a shark’s dorsal fin. The island itself is located around 300 metres from the South east coast of Koh Tao.
What it is like to dive at Shark Island
While diving here, you will notice a variety of depths, depending on your navigational position around the island.
If you descend to the bottom and slope down into the sand you will find the depth ranging from 18 – 25 metres, however it is very easy to shallow up and enjoy a visual safety stop at 5 metres.
At shallower depths you can appreciate the richness of marine life, frolicking along large boulders and rock formations.
Abundance of Marine Life at Shark Island
Shark Island is one of the only dive sites lucky enough to be blessed with soft purple tree corals blanketed across the rocks.
This, plus gorgeous gorgonian fans and whip corals make this dive site more like an underwater meadow.
There is so much to see here and is one of the most diverse diving sites on Koh Tao.
As you circle around the island you will notice schools of Butterfly fish, Bat Fish and yellow tailed barracuda.
Take a look underneath rock overhangs and enjoy a Blue spotted Ray staring back at you.
Don’t forget to check every crevice, as you may find something small hiding inside.
This is the perfect place for Nudibranch lovers. If you are lucky, you may even spot a turtle or Whale Shark cruising around.
Watch out for strong currents
