Here’s the official answer: The O2 Arena is at Peninsula Square, SE10 0DX. But that’s a useless fact unless you have a helicopter. The real answer is: it’s at the end of the Jubilee Line.
Take the Tube to North Greenwich station. That’s it. That’s the trick. When the train doors open and you smell river air and anticipation, you’ve arrived. The station was literally built just for this one giant dome. It’s like a VIP entrance for a spaceship.
Fun fact: getting off at North Greenwich means you bypass most of the local traffic. The locals in Greenwich Village have a special secret entrance through a foot tunnel that’s older than your grandma’s teacups. But don’t use it if you’re claustrophobic—it’s a dark, damp tube under the Thames that smells like wet socks and history.
