Bon Soong Wreck is one of the best wreck dives in Thailand simply because of the abundance of marine life and because of the large number of fish that divers can spot on the site. This dive site is a wreck of a boat that sank about 20 years ago. It lies at around 20 meters with the top sitting at around 15 meters. The wreck is isolated and sits on its own in a large expanse of the ocean. Because of this, the fish have little other hiding spots and so have congregated on this wreck. It has been said that divers will normally see over 100,000 fish on one dive.

The wreck itself was in one piece but during the 2004 Tsunami, the boat was split into three separate pieces making it a great spot for exploration. The different pieces now have many nooks and crannies all of which can be explored.

Smaller fish that can be spotted include many lionfish, triggerfish, angelfish, moray eels, and schools of puffer fish. Stonefish, dragonet fish, frogfish, cuttle fish, and flounders can all be seen on the wreck. Divers will be amazed of not only the different species to be spotted but also their quantities and divers can see crustaceans such as shrimps and invertebrates such as nudibranchs, in the hundreds. Photographers will need to spend several dives on this wreck to capture just some of the marine life on the wreck.
