Guguan Island Introduction
Guanyin Island is located northwest of Baisha and southwest of Jibei Island. It is a tableland formed from basalt, approximately 1 kilometer long from north to south, and is the largest uninhabited island in the Penghu archipelago. The island features porous basalt in many areas, with a surface layer covered in iron-rich sandstone, creating a striking contrast. Guanyin Island is an island in Baisha Township, Penghu County, Taiwan, and it is also the largest uninhabited island in the northern sea area. The island runs north-south and is about one kilometer long, primarily consisting of four landmasses and three small isthmuses that form a tableland. The northern coast has a large wave-cut platform, while natural white sandy beach bays exist on both the east and west coasts. On Guanyin Island's harbor, there is a "Yinglun Shipwreck Monument," which commemorates the location of the island's highest point. The wave-cut platform on the northern coast is a renowned natural laver production area, known for its high quality. Every winter during the harvesting season, villagers from Zhikeng Village flock to the area by boat to gather laver, creating a bustling scene reminiscent of a lively seafood market. It is famous for its wild laver production, which locals refer to as "black gold." The northern side of Guanyin Island is a natural wild laver area that is completely unpolluted, with the growing season for laver running from the end of October to the end of March the following year. During winter, strong northeast monsoons generate waves that promote laver growth, making it the harvesting season, also known as the "black gold picking" season. The waters between Guanyin Island and Baisha Island are the largest fishing grounds for silver-stripe round herring, with the spawning season occurring from April to September each year. In May, when the herring spawn, there is a fishing ban to ensure the sustainability of the herring population.
