StandoutExceptional marine biodiversity

The HTMS Phratong wreck, resting just off Koh Phra Thong, is one of those dives that feels like a proper discovery, even if she’s been down there since 1989. We love how the wreck really draws in the bigger pelagics, especially around the bow where those massive schools of fusiliers swirl. You’ll often spot trevally hunting amongst them. Dropping down, the ship’s structure is still largely intact, offering some interesting swim-throughs if you’re comfortable with overhead environments. The wheelhouse is usually our first stop. Keep an eye out for ghost pipefish camouflaged along the mast and the various anemones that have taken root. It’s not an especially deep wreck, which means plenty of bottom time to explore the nooks and crannies where groupers hide. Our favourite memory here is always the sound of cracking coral from parrotfish, a surprisingly loud soundtrack to a calm dive. Go early in the morning to beat the crowds; the visibility tends to be best then too.
