You'll hit a top speed of 15mph as you soar through the twists, turns and drops of the 173m long slide, Helix. This is an adrenaline-pumping activity which is not for the faint-hearted! For a slower-paced, but even more captivating, experience - take in the horizon-expanding views from the top of the ArcelorMittal Orbit 360 viewing platform. You'll get unparalleled panoramic of central London, as well as fantastic views across the Park.
