My friend sent me this and I thought, wow, I would love to visit this tea house. But to get there, I have to take a mountain trail in China; specifically, Hua Shan mountain near Xi’an, ShanXi Province.
Update: It turns out that this trail is the popular Mount Hua Pilgrimage. Supposedly, the Chinese government has made the pilgrimage much safer by adding wider and less dangerous paths.
I believe this post is the original. There is also a video of the plank path.
