Yinu waterfall is unfortunately located 2 kilometers past Yunlong Waterfall. It is a nice waterfall but it is less impressive and very few people hike to Yinu waterfall. Perhaps this is why the name translates to One Girl (single girl?). Yinu waterfall has several waterfalls tumbling down the cliff and can be difficult to photograph.
The hike – Yinu Waterfall is about 6 kilometers from the Dongbu Hot Spring trailhead. The trail begins steeply until you reach the small temple with refreshments and a toilet. Not long after that the trail levels out and you hike along a steep V-shaped valley. The trail is well maintained and heavily used until the Yunlong Waterfall. After that the trail is less traveled and it is washed out in several places. There are temporary routes to easily avoid the dangerous sections but this can change after any heavy rain.
How to get there – Take highway 21 from the north or south to Dongbu Road. It will be a short drive to Dongbu Hot Springs crossing the new Dongbu bridge. The trailhead is located shortly to the southeast of Dongbu Hot Springs but it’s best to park in the large visitor parking lot at the green suspension bridge. Walk across the bridge, up the hill and turn left at the road. You will see the mossy steps of the trailhead on the right about 50 meters down the road.
Other info – No permit or entry required for dayhikers. You will need a permit to camp in Yushan National Park (advance notice required). Camping is available at Lele cabin 1 km before Yinu Waterfall.
