Why dive here
With 41+ marine species recorded in the area - including seahorses and sea turtles - NAM SANH offers some of Hoi An & Cu Lao Cham's richest wreck diving. Water ranges 24-31°C, warmest June, August, September.
Nam Sanh is an oddball, and we love it for that. This isn’t a deep, dramatic wreck for technical divers. No, the Nam Sanh is a beached steamship, run aground by Typhoon Hester in 1971, and now sitting literally on the shoreline. It’s barely submerged, the bow often poking out of the water like a rusted warning sign. We’ve even walked on parts of it during particularly low tides. Diving here is more like an archaeological snorkel. You’re weaving through the skeletal remains of what was once a 46-meter vessel, now a jumble of metal plates and twisted girders. Sunlight spears through the gaps, illuminating schools of tiny damselfish darting between the rusty bulkheads. We’ve found surprising numbers of moray eels here, tucked deep into the darker recesses, and plenty of crabs scuttling across the barnacle-encrusted hull. It’s not about grand scale, but intimate details – the way a coral polyp has colonised a rivet, or a juvenile snapper sheltering in a cracked porthole. It’s a fascinating glimpse into history, perfect for photographers who appreciate the interplay of light and decay, or anyone who enjoys exploring a wreck without the pressure of depth limits. Just watch out for sharp edges; this old girl is definitely a bit dangerous.
