Nanfang Macao is the largest continental island in East Taiwan. Because of the Kuroshio currents in the offshore waters, many kinds of fish migrate back here, forming a fishing ground with abundant catch. It is one of the three major fishing ports in Taiwan. Nanfang Macao fishing port is also known as the home of mackerel. Every year, the promotion activities of Nanfang Mackerel Festival are held in Nanfang Macao. There is also a bridge connecting the fishing ports of Su-Macao and Nan-Nan-Macao, and a viewing platform for people to view the whole fishing port.
