About this site
Southwest Pinnacle sits off the southwest side of Koh Tao, an island in Surat Thani province on Thailand's Gulf coast. It is a granite pinnacle formation reached by boat from the island's dive centres, with a series of submerged rock formations breaking up the sandy terrain nearby. The site reaches a maximum depth of around 25 metres over a rocky bottom, and is rated an advanced dive due to strong currents that also make visibility changeable depending on sea conditions. Divers regularly encounter barracuda, batfish, fusiliers, grouper, snapper, and even whale sharks passing through, and reported sightings also include angelfish, bannerfish, clownfish, damselfish, moray eels, nudibranchs, pufferfish, reef sharks, stingrays, trevally, and leopard sharks.
