The Fu-tzu Cliff is a rare weathered terrain landscape, and after a trail is created along the crumbling wall, you can enter the Batongguan ancient trail. The unpaved, primitive sandy trail is almost one-way in width. In the past, this area was often rocky due to the fragile shale geology, but in recent years, management and the erection of guardrails and ropes have reduced the risk of passage, making it suitable for hikers who like a little challenge.
