However, it's quite physically demanding, as it involves hiking uphill from Guanzhugou, and going to Zedangcuo from Emangou requires a long round trip; the boardwalks are damp and covered in moss, so be sure to wear non-slip shoes. Supplies are scarce inside the scenic area, and cell phone signal is intermittent. The two valleys are quite far apart, making a self-driving trip more suitable. The combined ticket is valid for two days, but if you're short on time, your visit will be rushed.
