Sitting a spine-tingling 1,400m (6,233ft) above sea level on the side of the Tianmen Mountain, this glass walkway has got to be one of the least convincing structures included on our list.

When quizzed on the safety of the structure, a spokesman from the local tourist office stated that if hit by a falling rock from the mountain, the walkway is “designed to shatter but not break.”

Somehow we don’t find that answer entirely convincing.

On the bright side, this is one of the more adventurous features in this post, and the photographs you could get would fuel your instagram for a lifetime.
