Old Jetty Wreck - Koh Tao
The Old Jetty Wreck, sitting in just 6 meters, might not sound like much on paper, but it’s one of Koh Tao’s real charmers for a relaxed dive. We love this site especially when you're looking for something calm and a little different from the usual pinnacles. It's really just the remains of an old wooden jetty, collapsed and sprawled across the sand, but it's completely overgrown with sponges and soft corals now. You can weave between the old wooden piles, which are surprisingly intact in places, and peer into the nooks and crannies where juvenile groupers and lionfish often shelter. The entire structure is blanketed in a beautiful, healthy seagrass bed, which means we often spot green turtles slowly munching away, completely unbothered. It's a fantastic spot for photographers, especially macro enthusiasts, given the slow pace and shallow depth. Our tip? Go early in the morning when the light shafts through the water – it makes for some stunning visuals and you'll often have the place to yourself.
