The weather is cool, with unique ethnic characteristics. From Chongqing to Wulong by train is a good choice, affordable, good scenery. After arriving at Wulong, there is a bus going to the scenic spot one kilometer away, 18 yuan per person! But I suggest that we can take a private car. It costs only 80 yuan for five of us to go up the mountain. It takes about 30 minutes because it's a mountain climb. When you get to Wulong Tourist Reception Center, the ticket window of Tiankeng Village is a separate window. When you walk past, scalper ticket vendors will come to introduce Tiankeng tickets to you. It's quite economical and true to buy 110 at the window and 90 at the hands of ticket vendors. The ticket includes a special fare of 40 yuan for scenic spots, so if you go to any scenic spot, as long as you take a tourist bus, you will not charge. When I first entered the stockade, I felt bored with it. The mountain road was long and there was no scenery. Looking down, you may dream of seeing a few scattered earthen houses, with the feeling of being directly called into a pit, but the performance after going down is really wonderful, there is also a human culture, if you like the customs of famous ethnic groups, it is absolutely worth visiting. The performance is over, and one is beginning to be overwhelmed. It is suggested that the play time should be about 3 hours.
