Youling Waterfall (Spirit Waterfall) and Shuiliandong Waterfall (中文版: 幽靈瀑布之水簾洞) are easy to get to tall waterfalls in Taoyuan, Fuxing county (桃園縣復興區)
The main trail is very easy. It has a railing and everything. It's impossible to get lost, but will only take you to Shuiliandong Waterfall (水簾洞瀑布), which is actually an artificial structure built to protect the river from landslides. If you're feeling very adventurous you can climb over the top of the barrier and hike upriver to the next one, which looks similar in the satellite photos.
The secondary trail takes you to the bottom of Youling Waterfall ( 幽靈瀑布). Just follow it down to the main river and go up the first stream that you get to (not the main river). The hike is short, and not difficult, but it goes through the river, so the last 20 meters might be troublesome after a hard rain. This lower trail is more interesting and more beautiful than the trail up top, so I recommend going down to the bottom first. You can stand under the waterfall, but it's too shallow to swim.
There is a nice flat area that would be great for camping next to the parking area, but I expect there are a lot of mosquitoes around there. Might be nice in the winter.
