321 meters: Royal Gorge Bridge, Colorado, United States

The Colorado-based bridge was the highest suspension bridge in the world for nearly 75 years, until 2001 when the Liuguanghe Bridge in China surpassed it.
The Royal Gorge Bridge is by far the highest bungee jumping spot. A series of adrenaline-pumping activities are held daily.
The "thrilliest" are the “Go Fast! Games” -- highly competitive and fun games held in the last weekend of September.
