The Suhua Secret Land Lujiao Creek Waterfall, also known as Guanyin Stone Waterfall, is located in Nan'ao, Yilan. It has four sections of waterfalls where you can rappel, which is the best experience for beginners. Unlike river tracing, which is to go upstream from downstream, canyoning is to rappel from upstream. In the valley, you need to use various techniques (including rappelling, climbing, swimming, sliding and diving, etc.) to go down the stream. It is a unique experience and a great way to explore Taiwan's valleys.
