Shensian Valley is located at the confluence of Fengmei River and Bilin River, both the up-stream tributary of Donghe River. Its powerful impact due to water flow has created a several meter gap between bedrocks, resulting in the beautiful scenery of flowing fountain and pouring waterfall. The entrance of the trail is just next to Miaoli County Highway Mo. 21 and takes only 5 minutes to reach there.
