Longmen Gorge

The Pasnanavan Historic Trail, which crosses the Liugui District of Kaohsiung City and Yanping Township in Taitung County, was built in 1924. It starts from Liugui in the west and reaches Taoyuan in the east. The total length of the trail is about 126 km. In the past, the entry to the Trail was mostly from the west. Although the Governor-General in Taiwan found the passage long and difficult to get in and out, this trail was built nevertheless.

Today, the sections of the historic trail that was excavated above the rock walls of Longmen Gorge are steep, and both ends of the trail have collapsed, making it difficult to get there.
