－－－－－－The Best Diving Locations on Green Island－－－－－－
Green Island is a small volcanic island in the Pacific Ocean about 33 km (21 mi) off the eastern coast of Taiwan. It is 15.092 km2 (5.83 sq mi) at high tide and 17.329 km2 (6.69 sq mi) at low tide, making it the Republic of China’s fourth-largest island. The island is administered as Lüdao Township, a rural township of Taitung County and one of the county’s two offshore areas (the other being Orchid Island). The island once served as a penal colony for political prisoners during Taiwan’s period of Martial Law, although today it is primarily known as a tourist hotspot.
