Buying tickets at Hushan Great Wall was a bit of a hassle. You only need to select the number of people going, regardless of the number of people, and you can only select one person's ID. At the entrance, you just need to scan the QR code and enter according to the number of people you've purchased tickets for. It's quite hot every day, so I recommend buying tickets for the scenic area's sightseeing bus at the window. It costs 10 yuan per person. After checking your ticket, you can get on the bus if it's available. If it's not, you'll have to wait a while. If you prefer, you can walk the 500-meter route. If you're unsure about your ability to reach the summit, you don't need to buy the sightseeing bus tickets yet. There's also a ticket office for descending the other side after reaching the summit. The ascent is a mix of steep and gentle, while the descent on the other side is very steep.
