Shangping River (中文版：上坪溪) is a major tributary to the Touqian River in Hsinchu, Wufeng Township. It flows all the way from the top of Yaoshan Mountain, elevation 3000m. This guide covers a 7km section between Da'ai Waterfall, through Celestial Lake, and down to 南昌橋, which is not far from Ruifeng Elementary School. This is a good moderate-beginner route, with many small rapids, but only a few large ones. The biggest drop occurs just after Louping Bridge, and can be easily skipped if desired. Along the route there are also 2 bridges (Louping and Wufen Bridge) which I recommend skipping because there may be iron bars from old bridges in the river. On the way you will also pass the ruins of an old water park.
Downstream from 南昌橋 is also raftable, but due to the frequent occurrence of damaged man-made structures in the river I recommend stopping at 南昌橋 bridge. The route is also accessible from further upstream at Qingquan Village or Maibolai River, but this is a more advanced route for white water kayaking.
Other attractions in this area also include Baxian Waterfall, which is further upstream, and Guanyin Waterfall, which is near the parking area, and Silver Thread Waterfall, which is on the way, but takes 80 minutes to climb to.
