Colorado Cliffhanger Colorado, USA

It’s not marketing hyperbole. The Cliffhanger roller-coaster at Glenwood Springs literally dangles on the edge of a two-kilometre-high mountain face. The rollercoaster was relocated from Branson, Missouri, and now you can feel the adrenaline rush through you as you flip and turn on this white-knuckle fun park ride.
