Dongju Island Introduction
About 1 kilometer southeast of Jishan Island, four islets formed by basalt reefs can be seen. The magma flow has created various columnar joints in different directions. Through sea erosion and weathering, nature has sculpted the rocks here into exquisite and unique shapes, earning it the beauty reminiscent of Guilin's landscapes. The undulating terrain has resulted in clusters of sea-eroded columns, and between these columns, a rare "line of sky" spectacle has formed, making one feel that "such scenery should only exist at the Donggou Islets, nowhere else in Penghu can it be found." The entire island of Donggou is composed of dense columnar basalt, which is dark in color, and like Jishan Island, it often contains lump formations of olivine in the basalt. In winter, the island's reefs, similar to those of Jishan, cultivate natural laver, which is a common industry owned by nearby villages and often brings significant wealth to the residents. Since the island is part of a conservation area, human interference is minimal. In summer, nearly a thousand Black-tailed Gulls choose this place as a breeding ground, making it the most important habitat for Black-tailed Gulls in the northern waters of Penghu. Taking a boat to the nearby waters allows for easy appreciation of the graceful dance of the Black-tailed Gull flock.
