About this site
Jiajing Island (加井岛) is a 0.14 km2 rocky islet about 1.5 km off Shimei Bay, Wanning, with coral reef on its near-shore seabed and water 15–23 m deep around it. Diving is done all the way round the island from about five entry points, usually two or three dives a day, with 5–20 m visibility and the calmest sea from April to October. Winter swell on the eastern side lowers visibility.
