The place we went to was 金山岭长城 or jīnshānlǐng. Apparently fewer tourists go to this section of the wall, so we were excited to be one of the few there. Of course, it was like 200 of us attending so maybe not that few people. We took some buses provided by PiB to the main entrance. Then walked a long way through some yellow, wooden bridges, down a long, long road, until we arrived at the foot of the wall. It was actually very commercialized, with carts ferrying people willing to pay up, and many vendors and small restaurants all the way up. Not the Great Wall I envisioned but nice nonetheless.
