Sanxiantai Scenic Area Introduction
Situated in the northeastern part of Chenggong Township, Taitung County, Sanxiantai covers an area of approximately 22 hectares, with its highest point reaching about 77 meters above sea level. The geology belongs to the Dulan Mountain block, and it was originally a cape, but due to coastal erosion, its neck gradually eroded, transforming it into an offshore island. The island is surrounded by coral reefs, teeming with tropical fish beneath the waters, making it ideal for diving and swimming. As a small island formed from volcanic eruptions, it features unique rock formations, including natural wonders related to the Sanxiantai legend, such as Xianjian Gorge and Hehuan Cave, and various coastal erosion features like sea arches, sea stacks, and wave-cut cliffs, providing visitors with a rich experience of exploration. Among these features, the three peaks formed by coral reef rocks are particularly distinctive. According to local legend, the Eight Immortals passed through the sea here, and Li Tieguai, He Xiangu, and Lü Dongbin once took a rest on this island, leaving behind their traces, thus the name Sanxiantai. In addition to its rich stories, Sanxiantai is known for its biodiversity, serving as an excellent habitat for marine birds. Grey herons can often be seen between the gravel, while terns are commonly spotted in the summer. The nearby waters are abundant with fish, making it a well-known fishing spot as well as a famous location for rock fishing. The island is home to coastal plants such as Lintou, Taiwanese jujube, white mangrove, and beach pea, making it an important site for studying coastal plant ecology and has been designated as a nature reserve. The southern end of the island extends to the coastal area around Jihci, where beautiful coral reefs and tropical fish are found, and the Taiwan endemic species, Taiwan Acropora, also lives beneath the waters here, making Sanxiantai one of the most beautiful underwater landscapes along the Huadong coastline.
