The Tower is an iconic Las Vegas fixture that stands out in the city’s skyline. It is by far the best spot to see the entire city and the valley surrounding it.

The Stratosphere Casino Tower is also the site of several unique, adrenaline-pumping adventures. SkyJump is an open-air jump from 829 feet straight down to the neon-lit Strip. At the launching pad on the 108th floor of Stratosphere Casino, jumpers are strapped into a harness and attached to a cable connected to a “descender.” After they jump, moments before they reach the ground, the machine slows down the fall for a safe landing.

The Big Shot is another thrill ride in which strapped participants are shot at 45 miles per hour 160 feet into the air from a 921-foot-high platform. Insanity - the Ride is a huge mechanical arm that extends 64 feet at a height of over 900 feet over the edge of the Stratosphere Tower. It then turns its strapped riders upside down, offering them truly unique views of Las Vegas.
