Dongji Islet Introduction
About 1 kilometer southeast of Jishan Island, four islets known as Dinggou Islets can be seen on the sea surface, formed by basalt reefs. These were sculpted by the flow of magma, creating various directions of columnar joints. After undergoing marine erosion and weathering, nature has further refined the rocks, earning it a reputation akin to the scenic beauty of Guilin. The undulating terrain gives rise to a cluster of sea-eroded columns, among which the "Sky Line" phenomenon occurs, creating a rare scenic view that evokes the sentiment of "this scenery should only exist in Dinggou, nowhere else in Penghu can it be found." Dinggou Islet is completely composed of dense columnar basalt, dark in color, similar to Jishan Island, often containing olivine clasts within the basalt. During winter, the island's reefs, like those of Jishan Island, nurture natural seaweed, with fishing rights belonging to nearby villages, often bringing substantial wealth to the residents. Due to its status as a protected area, human interference is minimal. In the summer, nearly a thousand White-browed Crakes choose this site as their breeding ground, forming the most significant habitat for White-browed Crakes in northern Penghu. Taking a boat to the nearby waters allows easy enjoyment of the elegant dances performed by the flocks of White-browed Crakes.
