Similan Dive Sites – Koh Tachai Pinnacle

Koh Tachai Pinnalce is a great site, but one of the most frustrating due to it’s currents. This is a beautiful site with the potential for Whale Sharks and Manta Rays. At the Plateau on the top we frequently find Frogfish, Ghost Pipefish and other oddities.

The current is strongest around the Full and New moons, and because of it’s location this is the site that has the strongest of them all. Always wait for your DM to do a current check before jumping in! Use the line for ascent and descent and get ready for a great dive!

There are just so many nooks and crannies to poke around in, that you will find yourself annoyed with your lack of bottom time. I have actually missed a Whale Shark passing by because I was so enthralled with a Flabellina.

In the depths there are Leopard sharks laying in between the rocks. If you are early in the day there are frequently Black and White Tip Sharks and Rays as well. Big schools of Barracudas circle.

After spending a fair bit of time at depth, the shallows offer up the smaller treats and reward the keen eye. Once you see a frogfish, you’ll spend the rest of the dive looking in the smallest bits of coral for more.

The top if the pinnacle is 12 Meters ( 40 feet) so watch you air! The ascent should be on the line. All divers should have a safety marker buoy so that there in case the current takes them away from the boat.

We reserve this dive site for the more experienced divers due to both depths and currents. Worth it!

The currents are strong and the less experienced Divemasters, or those new to the area often find them selves doing blue dives aka “looking for Whale Sharks”

Bottom is 30-40m and the top is 12m, so most of your time is spent around 18m.
