If you want to walk the Great Wall of China, you need to book with Viator for the Nutianyu Great Wall trip, you ride the ski lift up, and the Luge down. Our driver was excellent,his name is BRUCE,ask for him,he got us to the Great Wall using back roads because fog had closed down the byway. We were in a travel group of 12 and we were the only ones to book with Viator,we were also the only ones to actually walk the Great Wall, there are 1100 to 1400 steps up to the Great Wall if you don't take the chair lift,and they say it is tougher coming down. Ask for BRUCE and he will get you there and back.
