Dinggou Islet Introduction
To the southeast of Jishan Island, about 1 kilometer offshore, you can see the four Dinghou Islets made up of basalt reefs. Due to the outflow of lava, various columnar joints have formed in different directions. With subsequent coastal erosion and weathering, nature has sculpted the rocks here into more delicate and unique shapes, earning it the reputation of being as beautiful as the landscapes of Guilin. The undulating terrain has created groups of sea-eroded pillars, among which there is a remarkable scenery known as "One Line Sky." This rare view gives visitors a sense that "this scenery should only be found at Dinghou, nowhere else in Penghu." The entire Dinghou Island is composed of dense columnar basalt, with a dark color, similar to Jishan Island, where basalt often contains clusters of olivine. In winter, the island's reefs, like those of Jishan Island, are covered with natural nori, which are a common industry owned by nearby villages and often provide a substantial income for residents. Since the island is part of a reserve area, there is little human interference. During summer, thousands of whiskered tern choose this place as their breeding ground, creating the most important habitat for whiskered terns in the northern region of Penghu. Taking a boat to the nearby waters, it is easy to enjoy the elegant dance of the whiskered tern flock.
