Sanxiantai Scenic Area Introduction
Sanxiantai, located in the northeastern part of Chenggong Township, Taitung County, covers an area of approximately 22 hectares, with its highest point reaching about 77 meters above sea level. Its geology belongs to the Dulan Mountain block, originally a cape, but due to seawater erosion, it gradually eroded its neck and became an offshore island, surrounded by coral reefs and inhabited by tropical fish, making it suitable for diving and swimming. As a small island formed by volcanic eruptions, it features unique rock formations, including natural wonders related to the Sanxiantai legend, such as Xianjian Gorge and Hehuan Cave, as well as coastal erosion features like sea erosion gullies, pots, columns, and concave walls, offering a rich experience for explorers. The three peaks formed by coral reef rocks are particularly unique, which is why local folklore holds that during the crossing of the sea by the Eight Immortals, Li Tieguai, He Xiangu, and Lü Dongbin once rested here, leaving behind traces of immortals, thus named Sanxiantai. In addition to its rich stories, the biodiversity of Sanxiantai provides an excellent habitat for marine birds, with rock herons occasionally seen among the gravel, and summer visitors often spotting terns. The nearby waters are abundant in fish, making it not only a fishing ground but also a famous rock fishing spot. The island is home to various coastal plants such as Lycium barbarum, Taiwanese jujube, white-flowered tree, and beach pea, making it an important site for studying coastal plant ecology, and it has been designated as a nature reserve. The southern tip of the island, surrounding the Jiayi area, features beautiful coral reefs and tropical fish, where the endemic "Taiwanese gorgonian coral" thrives beneath the surface, making Sanxiantai one of the most scenic underwater landscapes along the coastal line of Hualien and Taitung.
