Jiankou section, Great Wall of China
Since the segment is so remote and not a tourism hotspot, it hasn’t had the continuous maintenance and preservation work seen on the Badaling section. Parts of it have dangerously eroded, some have collapsed completely. Project manager for the Great Wall Protection Project Ma Yao told the BBC, “Every year, maybe one or two people die hiking on this part of the wall. Some from hiking and falling down, dead. And some from being hit by lightning.” While visitors aren’t prohibited from visiting the wall, it’s not easy to get to, challenging to climb, and its steep design, narrow passages, and eroding architecture make it a particularly dangerous destination. It is out of reach for the casual tourist, recommended only for the most experienced hikers and climbers.
