I really want to do this trail. China has never been high on my list of places to go (due to pollution and corruption), but I can’t deny there are some really potentially amazing places to visit.
Thankfully I’m okay with heights as long as I have a secure harness — I climbed Half Dome a couple years ago and was one of the only people who had a harness for the cables (no regrets!), and when I rappelled for the first time, my guide was impressed with the speed I flung myself over the edge once I was sure that my harness was properly secured. So while the person in the video isn’t using a harness (not very smart, in my opinion), I feel that I would pretty confident on that trail if I did have one.
