StandoutExceptional marine biodiversity

Chinese Wall, off the southern tip of Koh Miang, is less a wall and more a jumble of massive granite boulders. They stack from the surface down to around 30 meters, creating a maze of swim-throughs, overhangs, and small caverns. It’s a fun site to explore, like an underwater playground. We usually find giant morays tucked into the cracks, sometimes a few different species like the yellow-margined moray as well. The topography itself is the main draw here, making for an interesting dive even on quieter days. It’s a good spot for divers who enjoy poking around nooks and crannies.
