Erkeng Tunnel Introduction
The mountainous trails planned in Yingge District, New Taipei City, include a total of eighteen paths, suitable for hiking enthusiasts. The Er-Keng Tunnel is located near the Ying-Shih Pavilion along the Sun-Long Trail, and was once a light railway (coal transport railway) for transporting coal from the nearby Wu-Yi Coal Mine, which has been closed for many years. This small tunnel was originally part of a section of the light railway with a sharp bend. Later, concerned about safety, the relevant authorities straightened the pathway by digging this small tunnel. As the only small tunnel in the Yingge Mountain area, the Er-Keng Tunnel is only about ten meters long and five meters wide, making it a relatively rare mini tunnel that often arouses curiosity among hikers who come to view or take photos.
