Purchase rides before tower admission to avoid paying twice.
Stratosphere officials recently extended each ride to two circuits of the three-rotation track. By the end of the third rotation, the ride hits its maximum speed. That's all most riders can think about as the High Roller whizzes through the outer edge of the Stratosphere Tower 909 feet above the ground. The world's highest roller coaster, the High Roller makes six revolutions around 865 feet of track. The sharp 32-degree angles will leave you with a panic attack, if only for a moment.
