While we're all aware the O2 Centre is an entertainment venue and shopping centre rolled into one, did you know you can also climb up it, even in the dark? By scaling up the outside of the dome you get to see as far as 25 km away, including the twinkling lights of Canary Wharf, the Olympic Park and all the skyscrapers by night. Once you get to the top you you're free to have wander and snap away at the scenery, and you can even book a private climb with your pals, in a group of up to 30 people.
