HTMS Chang Wreck
Why dive here
HTMS Chang Wreck is a wreck dive in Koh Rong Archipelago, Cambodia. Water sits around 29°C.
The HTMS Chang, a former Thai naval vessel, sits upright in about 24 metres of water, making it one of our favourite wreck dives in Southeast Asia. It’s an intermediate dive, straightforward enough for confident newer wreck divers, but with plenty to explore for those with more experience. As you descend, the sheer size of the ship starts to reveal itself, looming out of the blue. We love the swim-throughs here, particularly navigating the cargo holds and engine room, where light shafts pierce the gloom, illuminating schools of fusiliers. She’s absolutely covered in life now. Look closely and you’ll spot pipefish clinging to the railings, and we often find cuttlefish camouflaged against the hull. The bridge is a tangled mass of soft corals, often swaying with the gentle surge. Our tip: go early in the morning for the best chance of spotting Jenkins' whiprays cruising around the deck. The visibility can vary, but even on an average day, the scale of the Chang makes it a truly impressive dive.
