Twins

Twins is a granite pinnacle site off Koh Nang Yuan, near Koh Tao in the Surat Thani province of southern Thailand. It consists of two submerged rock formations that give the site its name, with a rocky bottom reaching a maximum depth of around 18 metres, light current, and a beginner rating that makes it a popular training and check-out dive location given its proximity to Koh Tao's dive schools. Divers regularly find angelfish, clownfish, grouper, nudibranchs, pipefish, stingrays, and wrasse among the boulders, and there have also been reports of barracuda, fusiliers, ghost pipefish, moray eels, parrotfish, pufferfish, scorpionfish, sea turtles, snapper, and triggerfish around the site. Its sheltered, calm conditions suit a wide range of divers, from newer certification students to those looking for an easy, relaxed dive.
