If you’re afraid of heights, this is definitely not for you. This glass walkway at China’s Tianmen National Park gives walkers a view like no other. The walkway is 2.5 inches thick, 3 feet wide, and about 200 feet long. Walkers are required to wear shoe covers to keep the glass clean, so that the dizzying view below is not obscured.
