Let’s be real: the London Underground is your best friend for this trip. Hop on the Jubilee line (the grey one, not the boring grey one—that’s the Bakerloo). You want to go towards Stratford, because that’s the magical direction that ends with you at North Greenwich station.
Here’s the kicker: the station is literally built underneath the dome. You step off the train, ride a long escalator that feels like it goes to the center of the Earth, and poof—you’re inside. No map skills required. Just follow the sea of people wearing band t-shirts and smelling like overpriced beer.
Fun fact: The escalator is so deep that it takes a full 40 seconds to ride. That’s long enough to reconsider your life choices or, more importantly, check if your ticket is still in your pocket. Spoiler: it is. But you’ll check anyway.
Pro-Tip for the Tube: Avoid Rush Hour (Unless You Like Being a Human Sardine)
If you show up at 5:30 PM, you will be intimately familiar with a stranger’s armpit. Aim for 6:30 PM if the doors open at 7. You’ll still be packed in, but you’ll have enough room to breathe—barely.
