Jiangsu Province is located at the east coast of China, with a coastline of more than 1,000 kilometers along the Yellow Sea. Jiangsu is very flat and low-lying, plains are covering 68% of its total area, another 18% are covered by water. It borders Shandong in the north, Anhui to the west, and Zhejiang and Shanghai to the south. The southern parts are crossed by the Yangtze River.
Most of the province lies less than fifty meters asl. And while those plains are very fertile, irrigated by an well developed system of canals, it is not very ideal for the formation of caves. Still there are some areas with hills, the highest point is Mount Yuntai (625m asl) near the city of Lianyungang.
A karst area with several show caves is located near Yixing, on the west bank of Taihu Lake. The area is also famous for its pottery, which has been made here for 5,000 years. Especially the pottery from the Ming and Qing dynasties is world famous.
