There are plenty of buses that stop near North Greenwich station. But let’s be real: after a long concert, waiting for a night bus can feel like a survival challenge. It’s doable, but the Tube is just nicer for your feet after three hours of dancing.
Cycling is also a thing! There are Santander Cycles docking stations around The O2. If you’re the kind of person who arrives to a show sweaty but smiling, go for it. Just make sure you know how to get back to your hotel without looking at your phone every two seconds.
