If you’re feeling adventurous or you just really love walking alongside a dual carriageway, you can use Charlton station. It’s on the Southeastern line, and it’s about a twenty-minute walk to the O2. Some people love this route because it’s less crowded, but let’s be honest: it’s mostly industrial estates and car parks.
I once walked it in a pair of new boots and genuinely considered filing a formal complaint with my own feet. The distance isn’t bad, but the vibe is zero. You don’t get the buildup of energy you get from emerging out of North Greenwich into the neon glow of the arena.
What About the Cable Car?
Oh, you saw the Emirates Air Line cable car dangling over the Thames and thought, “That looks fun!” It is fun—for about ten minutes. But the nearest station for that is North Greenwich anyway, and the cable car drops you at Royal Docks. That’s a short hop over the river, but you’re still walking to the arena once you descend.
Pro tip from someone who tried to impress a date with it: do not use the cable car if you’re running late. It’s a tourist attraction dressed up as public transport. The views are killer, but your punctuality will be deceased.
