The verdant ecological cleansing was originally a security forest that accumulated sand under the Daxiang Bridge for many years, and was later developed into an ecological trail by the Forestry Bureau. Along the undulating sand dunes, visitors can pass through facilities such as the bamboo bamboo boardwalk, rope bridge, and lake viewing platform, with informative ecological signage about the plants. Finally, the trail circles back around the lake. Image source: Yunlin County Government / photographer
