The O2 in Greenwich is one of London’s most iconic landmarks and is now home to one of the capital’s newest and most exciting attractions, Up at the O2.

This 90-minute exhilarating outdoor challenge allows visitors to walk across the roof of the domed structure via a stretchable fabric walkway suspended 170 feet above ground level, between the O2’s distinctive yellow masts.

The observation platform at the summit offers spectacular 360-degree views of the capital and its many landmarks including the Olympic Park, Thames Barrier, the Shard and Canary Wharf.

Suitable for all ages from 10 onwards (and at least four feet – 1.2 metres – tall), the journey begins at Base Camp, where visitors are kitted out in specially-made climbsuits, shoes and safety harnesses and are taken by trained guides to the base of the tent to start their climb.

Climbs take place every 30 minutes and you will need at least 90 minutes to complete your climb. For more details on opening times and ticket prices, go to
