Walk on top of the o2

Pull on the harness, clip onto the safety rail and start climbing over one of London’s most recognisable roofs. Up at The O2 follows a fabric walkway suspended above the arena, rising gradually until you reach a viewing platform 52 metres above ground level. From the top, you can pick out Canary Wharf, Greenwich, the Thames and landmarks across east and central London before descending the opposite side. The O2 was originally built as the Millennium Dome, and its unusual roof is supported by 12 yellow masts representing the months of the year and the hours on a clock face. The roof walk turns that architecture into part of the experience: rather than viewing the building from below, you cross directly over it while attached to a continuous safety system. Climbs are available during the day and around sunset and twilight, so the view changes considerably depending on when you go. Allow around 90 minutes for the standard experience, including the safety briefing, fitting equipment, ascent, time at the summit and descent. Climbers must currently be at least eight years old, at least 1.2 metres tall and within the attraction’s harness size and weight limits; under-18s must climb with sufficient accompanying adults. Standard climbs currently start from around £37, and advance booking is the sensible option. Add this to your list and take the less conventional route across London’s skyline.
