Erkang Tunnel Introduction
There are a total of eighteen planned hiking trails in Yingge District, New Taipei City, suitable for hiking enthusiasts. The Er-Keng Tunnel is located near the Ying-Shih Pavilion along the Sun-Long Trail. It was previously a narrow-gauge railway (coal transportation railway) used for transporting coal from the nearby Five-Yi Coal Mine’s Er-Keng, which has been closed for many years. This section of the narrow-gauge railway was originally a sharp curve. Later, for safety reasons, the relevant authorities decided to straighten the path and excavate this small tunnel. The Er-Keng Tunnel is the only small tunnel in the Yingge Mountain area, with a length of approximately ten meters and a width of only five meters. It is a relatively rare mini tunnel, often arousing curiosity among hikers who come to view or take photos of it.
