Zip line craze hits Niagara Falls

Niagara Falls has become the latest natural wonder to add a zip line, offering thrill-seekers the chance to take an adrenaline-pumping plunge towards churning mist at speeds topping 64kph.

The elevated cable rides have evolved from a novel way to explore jungle canopies to almost necessary additions to lure tourists in the 21st century to established destinations.

It is a trend that has exposed a rift between those who approach nature like contemplative monks and others who require an extreme, Indiana Jones-style experience.
