Shenxian Valley is located at the Donghe River. The strong stream water cut out this breathtaking valley. The entrance of Shenxian Valley is right by the Miaoli Line No. 21. It takes you only 5 minutes to walk from the entrance down to the valley. Also, there's a Taiyai aboriginal featured suspension bridge that could take you across the Shenxian Valley to the Shemen Mountain Trail. It is a great place for a half-day trip.
