Erkeng Tunnel Introduction
In New Taipei City, there are a total of eighteen planned mountain trails in Yingge District, which are suitable for mountain hiking enthusiasts. The Er-Keng Tunnel is located near the Ying-Shih Pavilion on the Sun-Long Trail. It used to be a narrow-gauge railway (coal transport railway) used for transporting coal from the nearby long-closed Wu-Yi Coal Mine Er-Keng. This small tunnel, situated on a section of the narrow-gauge railway that originally had a larger bend, was straightened for safety reasons by the relevant authorities. Since the Er-Keng Tunnel is the only small tunnel in the Yingge Mountain area, measuring only about ten meters in length and five meters in width, it is a relatively rare mini tunnel, often attracting curiosity from hikers who come to watch or take photos.
