Someone apparently likened this section of the trail to the Great Wall of China, and the name Great Wall has been used to identify it since then.
It is probably similar in its winding fashion and the fact that at least one side is a very large drop to the bottom.
This photos does not convey that sense of the steep drop, but trust me, when you’re in that vehicle and you look over the side, vertigo and fear step in 🙂

Happy to see you are publishing the photos of this trip. So beautiful. Does educate us on what the interior of the country looks like.
Thanks A. Rose, these were from the 2009 trip, I am yet to process those from this year 🙂
I remember the bit near the top being the worst. It was so steep that not even the low range gearbox could keep the vehicle from speeding up, I had to use the brakes as well. Scary.
Maybe its a good thing we didn’t have to face it this year then? 🙂
