On the edge
There’s a small thrill that comes along with walking somewhere out of the ordinary. Stepping near steep drop-offs or moving just above rushing rivers or violent waves creates an adrenaline rush and offers the chance to see the world from a unique viewpoint. Some human-made walkways are extreme, consisting of nothing more than narrow boardwalks hundreds or even thousands of feet above the ground. However, these paths also provide views that just can't be matched by easier-to-reach places.
These perilous walkways are not ideal for those with vertigo or a fear of heights, but anyone able to overcome the basic human instinct to stay away from precarious places will be rewarded with a combination of excitement and beautiful panoramas.
Here are several extreme walkways that provide an experience and view worth the effort.
