🏝️ Green Island, Taiwan

Green Island, also known by other names, is a small volcanic island in the Pacific Ocean about 33 km (21 mi) off the eastern coast of the main island 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 seventh-largest island in Taiwan. The island is administered as Lyudao Township, a rural township of Taitung County and one of the county's two insular townships. 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.
