Take the subway to Dongzhimen Station in the morning. Take the 916 Express Line at the left-hand Dongzhimen Transportation Hub after leaving the station. Be sure to make the Express Line! After getting off at Huairou North Street Station in about an hour, someone asked to go to Mutianyu, and 50 yuan chartered car was sent to the entrance of the scenic spot. Be sure to bring some dry food and water in moderation, and then brush your cell phone two-dimensional code and cash it into the scenic area. There are many foreigners and beautiful women. There are more foreigners visiting the Wild Great Wall. Be sure to buy a ferry ticket or walk nearly 3 kilometers. Tickets are booked on the internet. When you arrive at the scenic spot, you can directly brush your cell phone two-dimensional code to take the ferry. After getting off, you can cash the ropeway ticket first, and then brush your cell phone two-dimensional code to enter the scenic spot to take the ropeway up the hill. Children are very excited to make ropeways and slideways. Online booking is also very convenient. They go directly to the entrance to report the order number for tickets. I'm on the ropeway up and down. After climbing the Great Wall, go back to the place of the lower ropeway and take a pulley down the hill. The slideway is fun, fun! The only disadvantage is that the idea is not exhaustive. Children should be seated with adults. My children are 8 years old and over 60 can't ride on the slide. The ropeway up the mountain is fearful of heights, so we should pay attention to safety. Mutianyu Great Wall is really good, you can't see the flag, most foreigners, children are suitable to go to the Big Corner Tower side of the tour, the journey is short, not that tired. Ferry bus must take, unless you are physically excellent, otherwise you will make the effort of flood and famine, ha ha ha!
