Why dive here
With 54+ marine species recorded in the area - including sea turtles, tiger sharks and pufferfish - MANGKORN KEOW offers some of Koh Tao's richest wreck diving. Water ranges 29-31°C, warmest April, May, June.
Mangkorn Keow, a trawler sunk back in '71, is one of those sites we always bring up when talking about Koh Tao wreck dives. It’s sitting upright at just 10 metres, so you’ve got plenty of bottom time to explore. The history here is a little murky, possibly a collision near Khao Sam Roi Yot Mountain, and then she was towed here to become an artificial reef. We love that this wreck has really settled into its role as a home for marine life. You'll find schools of yellowtail barracuda hanging around the superstructure, shimmering like a silver curtain. Look closely inside the holds, and you might spot a grumpy stonefish, blending in perfectly with the growth. The coral growth isn't ancient, of course, but there are some nice anemones and sea whips adding colour to the metal. We’d suggest going in the morning; the light filtering through the water onto the wreck is particularly beautiful then, casting long shadows and highlighting the details. It's a relaxed dive, perfect for photographers or anyone who enjoys the quiet contemplation of a wreck slowly succumbing to the sea.
