The Boonsung was a tin-mining dredger that sank in the 1980s in shallow water off Khao Lak. Over the decades the structure has collapsed and flattened, creating a low-profile wreck spread across the sandy bottom at around 18 to 22 metres. It is not a penetration wreck in the traditional sense. Instead, the collapsed plates, pipes, and machinery have created countless small habitats that attract an extraordinary variety of macro marine life. Think of it less as a shipwreck dive and more as a world-class critter hunt on metal substrate.

Visibility at Boonsung is variable and often lower than the clear-water sites around the Similan Islands. Expect anything from five to 20 metres, with the best visibility typically in the early season from November to January. The lower visibility is actually part of the site's appeal, as the nutrient-rich water supports the plankton that feeds the food chain sustaining all the macro life. Photographers should bring macro lenses and strobes rather than wide-angle setups.

Yes, the Boonsung Wreck is suitable for Open Water certified divers. The maximum depth is around 22 metres, there are no strong currents on most days, and there is no penetration involved. The main challenge is maintaining good buoyancy control to avoid stirring up sediment on the sandy bottom, which is important both for visibility and for protecting the delicate creatures that live on the wreck. Many dive shops in Khao Lak offer the Boonsung as a day trip, often combined with a shallower reef site.
