If you’re looking for things to do in Vegas that have a bit of wow-factor, then the Stratosphere Observation Deck is a must. For now, The Stratosphere’s 1,149-foot tower is still the tallest structure on the Las Vegas Strip. Elevators zip you up to the Observation Deck in less than a minute for a 360-degree view of the Vegas Valley. The windows extend out, so you’re not looking straight down through a typical wall of glass. Your eye is naturally drawn outward.
