To get onto the wall at Mutianyu you could either climb these steps or take the cable-car. After the exertions of Simatai to Jinshanling many people welcomed the opportunity for a more restful day at Mutianyu, and chose the cable car.

I took the steps, because I'm stupid like that, and I have to say it was an enjoyable climb. The steps weren't anything special, just wholly unexciting modern stone steps, but the company was good. :-)
