About Up at The O2
The O2, originally built as the Millennium Dome to house Britain's Millennium Experience exhibition in 2000, was converted into an entertainment arena and complex in 2007 and is now one of the world's busiest music and events venues by ticket sales. Up at The O2, opened in 2012, turned the building's distinctive tent-like roof into an attraction in its own right.
Groups of up to 16, fitted with safety harnesses, follow a guide up a fabric walkway that arcs directly over the curve of the dome's roof, climbing to a viewing platform 52 metres above ground level with panoramic views over Greenwich, Canary Wharf, the Thames and, on clear days, well beyond. No climbing experience or particular fitness is required, though the ascent is a genuine physical incline rather than a passive experience.

Different climb options run through the day and evening — daytime climbs, sunset climbs timed for golden-hour views, and twilight climbs to see the city's lights — plus a seasonal winter version, giving repeat visitors a reason to try it more than once.
The whole experience, including safety briefing and kit-up, takes around two hours, making it a half-morning or half-evening activity rather than a quick stop, best suited to visitors already in Greenwich or North Greenwich for other reasons, or those specifically seeking out an active viewpoint experience.
