These 450m-high crags require you to scramble up metal ladders and steps that are carved into the rock face to reach the top. No technical skill is needed, but it's an adrenaline rush nonetheless.
To reach the trails, walk to the main road from Pingxi train station and turn right. Just past the spiffy-looking red-brick school you'll see a set of stairs to the left and an English map board. Head up the stairs, and then after a five-minute walk along the path, look for the sign for Cimu Feng (慈母峰; Címǔ Fēng).
Follow the path as it alternates running atop a ridge and hugging a steep grey limestone cliff. In one to 1½ hours you'll reach a set of cement stairs. You can take these down to Pingxi (essentially completing a loop) or begin the better loop up to the crags, which can take another couple of hours to complete depending on your route. There are signposts everywhere, and while you may get sidetracked, you won't get lost.
