This dive site is a fantastic dive site and it was named after the many Tridacna giant clams that have colonised the wall. The area around the dive site, and throughout the Auri islands, are well known for having fantastically crystal clear water with stunning white sand beaches; the dives sites in the area, including Tridacna Wall, are equally stunning.

With a maximum depth of 30 metres and an average visibility of 20 metres, the Tridacna wall, also known as the Tridacna Atoll, is accessible via boat and both soft and hard corals are found in abundance. The drop off bottom contours makes it easy for divers to settle down on the sea floor to observe the schools of fish swimming by.

Despite being surrounded by Auri islands’ stunning and uninhabited white sand beaches, the huge plethora of giant clams is by far the main attraction of this dive site. Further marine fauna highlights are schooling bump head parrotfish and barracudas.

The sheer walls of Tridacna Wall are also home to species of flatworms, nudibranchs, blennies, flatworms, octopus, moray eels, cardinal fish, angelfish, groupers, damselfish trevallies, snappers, fusiliers, barracudas, sweetlips, butterflyfish, wrasses, parrotfish, surgeonfish, damselfish, anthias, batfish, and triggerfish. Divers can also expect to see many other shellfish alongside the clams, and crabs, lobsters, and many types of shrimps. Another treat for fans of historical artefacts is a trio of WWII fighter jets sunken nearby. For an unknown reason, they have sunk together and lie in formation in only a few metres of water.
