Here comes the practical application: the price of the volcano park is 54 yuan, and the site can be paid by Alipay WeChat or cash. The 54 yuan ticket includes the columnar section and the Black Fish River. If you want to buy a combined ticket of 15 yuan by hot-air balloon, you should go to the foot of Dakong Mountain and then go up to the left hand side. You should not buy the hot-air balloon ticket in advance. Otherwise, because of the weather problem, you can't really get it. There are 280 adult tickets and 200 children tickets. You need to queue up. Go early, or it will not sell if the wind blows. The safest thing is to arrive at 10 o'clock, and after 10 o'clock, eight Chengdu will not sell. It is recommended to go to volcano park by charter or by car. If you can go to the hot Sea tourist station and take a special bus to the triangle in the city, when I go, I go to the triangle. Ten yuan a person, five people drive, and ten yuan from the triangle to the volcano park. But! There is no car to Black Fish River with columnar joints! So I suggest chartering or driving by myself! If you go to volcano park and charter a car, it takes 200 trips to a point, and there is not necessarily a car! If you start chartering 250 yuan, you can go to three points, the Black Fish River in the columnar section of the Volcano Park. On the way back to the city, we will pass through Beihai Wetland. The ticket is 110 yuan. Perhaps unexpected, you can ask me questions.
