Scuba Junction - Koh Tao

Scuba Junction isn't one of Koh Tao’s big-name sites, and that's precisely why we love it. Tucked away on the island's eastern side, it's often overlooked for the more famous Chumphon Pinnacle or Sail Rock, but if you want something quieter and genuinely rewarding, this is our pick. Drop in here and you'll find a sloping reef that starts shallow and eases down to around 18 metres. It’s perfect for a relaxed dive, especially if you’re keen on slowing down and spotting the smaller stuff. The beauty of Scuba Junction is in its subtlety. We've spent many a dive here just watching the resident Banded Blennies dart between crevices, or trying to spot the elusive Telescopefish tucked into the staghorn coral. You’ll see plenty of Silver Demoiselles shimmering around the Brain coral heads, and often the larger Big-eye Trevally cruising past the deeper sections. Keep an eye out for the Common Coral Trout, too; they're usually easy to spot hovering near the rock formations. Current here is generally mild, making it a great choice for newer divers or those who prefer a less strenuous drift. It’s also often less crowded than other sites, which, in Koh Tao, is a massive bonus. Go early in the morning for the best light and the quietest conditions.
