The Sandiaoling Waterfall Trail stretches 2.71 km in total. The Sandiaoling waterfall group is also called the “Three-tier Waterfalls”: the first tier is Hegu Waterfall, the second is Motian Waterfall, and the third is Pipidong Waterfall. Because the hike is not difficult and the route is varied, it has become one of New Taipei City’s most popular mountain trails. After exiting Sandiaoling Station, follow the small path beside the railway to the former site of Shuoren Elementary School; the trailhead is just above. Along the way you’ll pass the three waterfalls, including the tallest and most voluminous, Hegu Waterfall, as well as the upper-and-lower linked Motian Waterfall (also called Yuemeidong Waterfall) and Pipidong Waterfall. Visitors can take their time admiring the spectacular falls, cliffs, potholes, and rock grottoes. The trail starts at the gate of the old Shuoren Elementary School in Sandiaoling. In earlier days this settlement was once thriving, with mines and the Pingxi Line’s engine depot located here; sadly, most of these industrial facilities have been dismantled and the school has long been closed. Traditional industries have declined or vanished, but Sandiaoling, nestled in its valley, still offers plenty of tourist resources, and holiday visitors flock to the waterfalls and old trails. The hike along the Sandiaoling Waterfall Trail takes about 1 hour 15 minutes. It was once the main venue for the “New Taipei City Mountain Festival,” surrounded by lush forested hills whose beauty makes every visitor linger!
