"Huanghuacheng Great Wall is picturesque, much quieter, much less developed and less known than other sections in Beijing. You could easily spend a whole day here."

"If you could visit only one, and want to enjoy a better views with less crowds, Mutianyu is right for you. http://www.wildgreatwall.com/mutianyu-toboggan-ride/"

"if you walk on south west part of Badaling, you can still enjoy the silence of Wall as most people walk towards north east part of it."

"The Palace is most often associated with the Empress Dowager Cixi, who resided here for much of the year. Compared with Forbidden City, the Summer Palace is more for pleasure and relaxation."

"Mutianyu is 1.5 hours (one way) from downtown Beijing and 1 hour from the airport by road. With the easier walking conditions and fewer crowds, Mutianyu is much more enjoyable to walk than Badaling."
