Queenstown, New Zealand, is the "Adventure Capital of the World," and the title for the scariest activity is usually a tie between the Nevis Bungy and the Nevis Swing. The Nevis Bungy involves a terrifying 134-meter (440-foot) drop from a high-wire pod suspended in the middle of a barren canyon; you experience 8.5 seconds of pure freefall, which is the highest in the country. If the vertical drop isn't enough, the Nevis Swing sends you hurtling through a 300-meter arc at speeds reaching 120 kph, often while hanging upside down or backwards. For those who fear heights but prefer a "mental" scare, the Fear Factory is a world-famous haunted house experience in the town center that uses live actors and psychological triggers to induce extreme terror, often causing many guests to use the "chicken out" exit. Another contender is Shark Attack, a semi-submersible watercraft that dives under the water and then leaps into the air like a predator, reaching high G-forces and speeds that can be deeply unnerving for those who aren't used to high-speed nautical maneuvers. Each of these activities is designed to push the human "fight or flight" response to its absolute limit.
