Southwest Pinnacle is one of Koh Tao’s most visually stunning dive sites and a firm favourite among underwater photographers. This cluster of submerged granite pinnacles hosts one of the most spectacular anemone fields in the Gulf of Thailand. We find covering the main pinnacle in a riot of colour from top to bottom. Giant groupers patrol the walls, barracuda schools drift past in formation, and on lucky days, a whale shark makes a surprise appearance. A must-dive on every Koh Tao fun dive programme.<\/p>\n

Southwest Pinnacle dive site Koh Tao: what makes it special?<\/h2>\n

Southwest Pinnacle is a cluster of submerged granite pinnacles located on the southwest side of Koh Tao, roughly 45 minutes by boat from Mae Haad pier. The main pinnacle rises to just 7 metres below the surface, while the surrounding structures extend down to 30 metres. Unlike open-water blue water sites such as Chumphon Pinnacle, Southwest offers a more sheltered configuration. It have with walls blanketed in extraordinarily dense marine life.<\/p>\n

Above all, what sets Southwest Pinnacle apart from every other dive site on Koh Tao (Thailand’s diving island) is its exceptional anemone field<\/strong>. The top and flanks of the main pinnacle are quite literally carpeted with anemones of every colour. It is precisely this sight, unique in the Gulf of Thailand, that has made Southwest Pinnacle a favourite among divers and underwater photographers alike.<\/p>\n

The anemone field at Southwest Pinnacle \u2014 the signature of the site<\/h2>\n

From the moment you descend, the anemone field at Southwest Pinnacle announces itself as one of the most visually arresting sights in all of Koh Tao. Hundreds of anemones sway gently in the current, each sheltering its own clownfish colony. It’s on terms of colour, density and sheer visual impact. Very few dive sites around Koh Tao can match what Southwest delivers within the first few metres.<\/p>\n

Beyond this visual spectacle, the pinnacle walls also hide moray eels, cleaner shrimps and a remarkable variety of nudibranchs for macro enthusiasts. As a result, Southwest Pinnacle satisfies both divers drawn by large animals and those. Who prefer to hunt for the smaller, hidden life tucked into every crack in the reef.<\/p>\n
