Dongji Island Introduction
Do you know that there is a national marine park in Penghu? The Southern Four Islands National Park of Penghu includes Dongji, Xiji, Dongyuping, and Xiyuping Islands along with the surrounding reefs and waters. Due to its sparse population, it maintains its primitive appearance and is an important ecological tourism destination. Dongji Island, the easternmost island, is the largest among the Southern Four Islands and is also the closest island to Taiwan's main island within the Penghu archipelago. It was once a transshipment point for maritime trade between Taiwan and Penghu. The nearby waters contain several spiral currents, often causing ships to run aground and sink, thus it is referred to as "Heishuigou" (Black Water Ditch). To ensure the safety of vessels, two lighthouses were built during the Japanese colonial period. The northern Dongji Lighthouse is the highest point on the island, and its black and white striped body is quite striking. Due to the historical presence of Japanese military forces, you can see the ruins of artillery barracks locally known as "Bingcuo" at the northeastern corner. From the visitor center, heading west to Bagua Mountain, and climbing to a higher point, one can overlook Dongji Port, Dongji Lighthouse, and the surrounding sea views. The rock layers of Bagua Mountain are elongated basalt, and on the left side, there is a circular rock resembling an eye, known as the "Eye of Dongji." The coastline surrounding Dongji Island is almost entirely made up of steep columnar basalt cliffs. There is a large sea erosion platform at the northeastern corner, referred to as "Daping" by locals, where a wealth of intertidal organisms can be discovered during low tide. Due to the rich basalt landscape, it along with Xiji, Touding, and Tiezha Island is collectively designated as the "Penghu Nanhai Basalt Natural Reserve."
