North Button Island is located about 10km east of Middle Andaman Island, south of Campbell Shoal and immediately north of Diligent Strait. This island has an exotic dive site. Divers can dive here very easily. The bottom mainly comprises coral covered rocks with patches of sand. The marine life includes humpback snappers, giant groupers and schools of spinyfoot and unicornfish. On the reef flat, divers can see boulder corals, staghorns, coral laminates and finger corals.
