Hi.
We will be in Beijing this Saturday (April 16th) and Sunday (17th)
There are two of us and we are planning on visiting the Mutianyu section of the great wall. We are hoping to visit it on the Saturday and the earliest we can depart will be late morning/early afternoon

My question is as we are short on time, how easy is to get there by bus and how do we get it? how long will it take? and also do you think we will have time to visit there in one afternoon? Finally is it easy to get the bus back too?

We are staying in The Dong-Cheng district of Beijing. I would be very grateful of any help.

Thanks
