Youyi, located in the mountainous area of Keelung, was once a prosperous mining settlement. In recent years, the Keelung Municipal Government has been revamping Youyi Ecological Park, creating footpaths and bicycle paths. This park is suitable for travelers who seek old memories or for outings for the whole family. The promenade along the Youyi River, with its clear water quality and slow flow, is very suitable for family and children. “Shigongtan” is one of the most popular attractions in Youyi Ecological Park.
