About Koh Tachai Pinnacle

One of Thailand's most exhilarating drift dives, Koh Tachai Pinnacle is a submerged granite ridge in open water between the Similans and Richelieu Rock. Strong currents attract massive schools of trevally, barracuda, and fusiliers swirling around the pinnacle. Manta rays and whale sharks are regular visitors during the high season, making this an advanced diver's dream.
