5. Tianmen Skywalk, China
Perched nearly 4,700 feet high, the Tianmen Skywalk hugs the sheer cliffs of Tianmen Mountain. This glass-bottomed bridge, just three feet wide, offers a vertigo-inducing glimpse straight down to the valley. Walking here is a heart-pounding thrill, ideal for adrenaline junkies craving epic views and a daring rush with every transparent step.
