Mystery Beach Waterfall （中文版：神秘海灘瀑布） is an neat waterfall that falls right onto the beach in Yilan, Nan'ao Township. The waterfall is located 4.3km down Mystery Beach so to get there you either need to drive an offload vehicle, or walk about 1 hour. The beach is very remote, which makes it a great place to see the milky-way on a moonless night. You can camp and swim anywhere.
Two hundred meters past the waterfall is the Mystery Beach Sea Cave. There are dozens of sea caves along the beach, but this one is the largest. Due to the risk of falling rocks, it's recommended that you camp just outside the cave, rather than inside it.
