I bought a Trip.com parent-child package, two big and one small 280, you can enter without changing the QR code, which is very convenient. Self-driving to the parking lot near Erxian Cave, take the scenic bus to various attractions, the specific site is the starting point - Xianpu Cave - Huangdaxian Palace - Chaozhen Cave - Shuanglong Cave, Curling Cave - Erxian Cave, and then walk hundreds of steps back to the parking lot. In addition to the Shuanglong Cave (and the curling hole) written by Ye Shengtao, several other attractions have neither characteristics nor cultural connotations. It is not as interesting as the underground Changhe Scenic Area of Lanxi. It is not enough to force the sale without buying. If the time is not abundant, go to Shuanglong Cave. The staff of the scenic spot have poor business ability. I asked a few how to go to Shuanglong Cave. No one answered accurately. You need to take the scenic bus for one stop and relay to the fourth station. It is only a simple answer. Because like taking a scenic car in Putuo Mountain, you can go from one stop to any other stop. I am very unaccustomed to the one-way ride of Shuanglong Cave.
