The Stratosphere is the tallest freestanding observation tower in the United States, but taking in the view isn't the only thing you can do at 1,149 feet. The thrill rides at the top give daredevils the chance to be dangled off the side of the building or shot skyward. If those rides are too sedate, you can literally jump off the building at the Sky Jump, one of the world's highest freefalls where the controlled descent will take you over 800 feet down in a hurry. The Stratosphere offers four rides: the Big Shot (perhaps the most popular), Insanity, X-Scream, and the Sky Jump. The view from here is incredible, whether you're enjoying it from the observation deck or as you're contemplating just how sturdy the equipment is.
