Similan islands diving

Elephant Head, Hin Pousar
This is probably the most famous dive site in the Similan Islands, it lies in between island 7 (Koh Payu) and island 8 (Koh Similan).
With three large rocks breaking the surface these granite boulders run down to over 50 meters. This is an exciting dive. Not too much coral growth but the way the boulders are lying on top of each other has left an intricate web of tunnels and swim- throughs. Large overhangs with oriental sweetlips and harlequin sweetlips which are only found in the Andaman sea hang around in small groups to escape the currents. Coming in and out of the tunnels keep an eye open for the colorful clown triggerfish and the white tip reef sharks resting on the bottom. Currents can be quite strong sometimes but this makes for an exciting and fun dive.


Koh Bangu #9 North Point
North point lies on the west side of the island with a dramatic underwater scenery of large boulders with canyons and swim throughs. As you descend down the line passed the tall fin bat fish and head through the tunnels, keep your eyes open for a pair of Napoleon wrasse. In between the large canyons grow large gorgonian sea fans with excellent soft corals hiding harlequin ghost pipe fish but a look out into the blue can be rewarding with frequent visits from the graceful manta ray passing over head.


Koh Bon - The Pinnacle
Koh Bon island lies 12 nautical miles south of Koh Tachaiisland and the dive site is located around 150 meters north west of the island and has no bouy line so location is by GPS. When the captain signals its time to jump into the blue and descend down to the pinnacles. The top is around 18 meters and continues to run down to over 50 meters to the sand bottom were the docile leopard shark sleeps while white tip reef sharks patrol the reef in search of a meal. These amazing pinnacles are covered with colourful soft coral trees, large gorgonian sea fans and barrel sponges running down the walls. With 5 species of clown fish in the magnificent anemones and their shrimp and porcelain crab hosts its difficult to keep your eyes of the pinnacles but a look out in to the blue can be rewarding with manta rays gliding around and the occasional whale shark. But don’t forget to keep a check on your air supply as its time to head back to the surface and leave these beautiful creatures behind.

Koh Tachai Island - The Dome
Koh Tachai lies 22 nautical miles south of Surin, the dive site is located around 200 meters south of the island and is marked with a bouy line which descends down to 16 meters to reach the top of the plateau. From here you decide which way to go ? North or South. North takes you over the plateau to the beautiful coral garden at around 22meters to 26meters with some of the best soft corals and sea fans in the area, which will keep underwater photographers busy. South takes you down over the large boulders to between 36meters and 40meters to reach the sandy bottom looking for the docile leopard shark and large stingrays. Up above schooling great barracudas with tunas and trevallys darting down to catch the baitfish hanging around the reef. With a multitude of small creatures to look at try not to forget a look into the blue to see the manta rays gliding past and the occasional whale shark make Koh Tachai a spectacular dive site.

Richelieu Rock
Richelieu lies 7.5 nautical miles east of the Surin islands national marine park. Here this large rock pinnacle just breaks thesurface at low tide and descends down to around 33 meters to the sandy bottom. The northern side has an excellent wall with lots of cracks and holes for you to look inside. The wall is covered with coral and zig zag oysters where you can find over ten species of moray eels like the commonly spotted white eyed, giant, yellow edged, and bartail morays or the shy dragon, leopard, honeycomb and zebra morays. The wall is all so home to many species of shrimps from the cleaners, anemone, saron, squat and the colorful harlequin shrimps. The west side contains mostly soft corals and sea fans with ghost pipefish and tigertail sea horses hiding in between the branches. But its here where we all so encounter large schools of silver jacks and bluefin trevallys with chevron and great barracudas too.
Its also home to the gentle giant the whale shark anywhere from 2 meter babys to 8 meter subadults. The walls seem to move with so much life or look closely at the camouflaged scorpion, stone and lionfishes that blend in to the rock. A truly spectacular dive site no matter what the visibility.
