Green Island

Green Island, also known by other names, is a small volcanic island in the Pacific Ocean about 33 km off the eastern coast of Taiwan. It is 15.092 km2 at high tide and 17.329 km2 at low tide, making it the seventh-largest island in Taiwan Area. The island is administered as Lyudao Township, a rural township of Taitung County and one of the county's two offshore areas. 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.
