How long does it take to leave The O2 Arena (and how to beat the queue)

What the exit crowd is really like

A near-full O2 empties into one district within minutes, so tens of thousands of people can be heading for the same station at the same time. Visitor accounts often describe waits of roughly 30 to 45 minutes to reach a platform at the busiest moments.

Treat that as a planning range rather than a fixed number. Your event, your chosen exit and even the weather change it. The point is to expect a managed crowd and plan for it, not to be surprised by it.

Why the queue forms

North Greenwich station is built for big crowds, and staff meter entry to keep things safe. The bottleneck is usually crowd control, not how often trains arrive, which is why the outdoor queue often moves faster than it looks from the back.

Phone signal and ride-hailing apps also slow down precisely when everyone opens tickets, maps and taxis at once, so a route you have not saved offline can be hard to load in the crush.

Decide your exit before the encore

The calmest exits are decided before the last song. Agree as a group whether you are leaving fast, waiting out the first wave, or taking the cheapest public-transport route, and share a meeting point in advance.

Standing still to debate inside a moving crowd is what creates the worst pinch points. Keep moving with the flow and make decisions while you walk.

Tactics that quietly save time

Letting the first wave pass is underrated: 20 to 30 minutes at an open, lit bar, cafe or seating area away from the doors can mean you walk straight into a queue that has thinned, as long as your last train or bus still runs.

It can also pay to walk one stop out to a bus heading away from the peninsula, or toward a DLR, Elizabeth line or rail link, instead of waiting in the main queue. A scheduled river boat can run shortly after major events too, but it usually needs booking ahead and has limited capacity, so never make it your only exit.

Whatever you do, follow the stewards and confirm services on the night. Station entrances in use, crowd routing and boat timetables all change by event.
