Er-Keng Tunnel Introduction
In the Yingge District of New Taipei City, there are a total of eighteen planned hiking trails, making it suitable for hiking enthusiasts. The Erkong Tunnel is located near the Ying Stone Pavilion along the Sun Long Trail. It was previously a narrow-gauge railway used to transport coal from the now-closed Wuyi Coal Mine's Erkong. This small tunnel was originally part of a section of the narrow-gauge railway that had a sharper curve. To ensure safety, the relevant authorities straightened the curve by excavating this small tunnel. As the only small tunnel in the Yingge Mountain area, the Erkong Tunnel is about ten meters long and five meters wide, making it a rather rare mini-tunnel that often attracts hikers' curiosity for viewing or taking photos.
