The Sandiaoling Trail (中文版：三貂嶺瀑布步道) is a 2.7km, 3 waterfall trail in New Taipei City, Pingxi District. The trail starts near Sandiaoling Train Station. Continuing hiking beyond the end of the trail will take you circuit from Sandiaoling Station to Dahua Station (or vice versa) for a total of 6.5 kilometers, which takes about 3 hours. There are also bus stops in the front and back of the trail. Check the included map for more information.
The trail is easy to follow, and not very strenuous.
If you started from the top, the first waterfall you would get to is Pipadong Waterfall.
200 meters later is Motian Waterfall, which has a cave behind it that you can crawl though for some cool photos.
850 meters later is Hegu Waterfall. It's not accessible from the trail (that I saw), so you'll have to rivertrace up from the bottom if you want to play in it.
