It is very convenient to book Zhangjiajie Tianmen Mountain tickets on Trip.com. The price is much cheaper. The original price is 258 yuan, and now it is only 225 yuan. You only need to provide your ID number and mobile phone number when booking. At the ticket window of the starting point of the Tianmen Mountain cableway, there will be a printed list, all of which are the list of people who booked on Trip.com. It is OK to only sign and indicate a few copies on the above, which is really very convenient.
