Koh Tachai Pinnacle (or Twin Peaks) is known for its impressive boulders, beautiful coral gardens and crazy currents, this makes it one of the most exciting dives on the Similan Islands liveaboard cruise. You descend down the buoy line on the east side of the pinnacle, using your arms to pull you down the rope as the current takes the rest of your body forcing you horizontal, make sure to hold onto your mask if you turn around to look behind you else the current can take it. Once down your dive guide will find ways around the pinnacle hiding you from the currents, weaving in and out of the massive granite boulders. The currents not only make for an interesting dive, they also bring with them the big fish which make this site a must to dive.
Schools of Long-fin Bat fish hang around nonplussed by the divers around them, huge schools of circling Barracuda on top of this pinnacle make a beautiful photo opportunity as you look up at them silhouetted in the light of the sun through the ocean ceiling. Giant Trevally, Tuna and Napoleon Wrasse are frequent here. As well as the graceful Manta Ray magically swimming back and forth, it is such an amazing sight that you will want to make more than one dive here.
The beautiful coral gardens on the north side of the pinnacle have some hidden wonders in them, Ornate Ghost Pipefish, Hawksbill Turtles, Sea Snakes, Devil Scorpion fish to name but a few. Explore the powerful granite boulders or the colourful corals, or just hang in the current holding onto the tops of the rock waiting for Mantas to pass you by, whatever dive you do you will love Koh Tachai Pinnacle.
