Climb The O2

At first you're bound to be a bit nervous. After all, it's not every day you set out to walk up and over one of London's most famous landmarks. And is IS pretty high out there. Once you get into your stride you'll be able to really enjoy the walk, hearing the hustle and bustle of London life and taking in the views as you go.

At the very top you'll be 52m off the ground on these O2 experiences!

Yes, I can be a bit windy up there. You'll be outside, climbing across that famous white-domed roof, so you're exposed to the elements.

Just wear casual clothing you feel comfortable in and make sure you wear or bring socks. That's because you'll be kitted out with a harness and a pair of specially soled sturdy climbing shoes for your climb the o2 experience.

Allow around 90minutes in total for these O2 experiences. The climb itself takes around one hour.

Yes you can, but only from the viewing platform at the summit of the climb. You'll need to make sure your phone or camera is attached or zipped away whilst you climb, so it doesn't fall.

The famous dome was built in 1999 to house the Millennium Exhibition, which ran from 1st January to the 31st December 2000. Once vacated, the O2 arena was built inside the dome, to become a music, leisure and events venue. Since opening in 2007, it has become the world's busiest music venue, selling over 1.8million tickets a year for concerts.

It's actually a plastic-coated fabric that is tensioned over the roof to create the iconic dome shape.

These experiences run in all weathers, but if the weather means the organisers deem it unsafe to run the activity, you will be able to rebook for another date.

It's no coincidence that the dome is 52m high - it represents the weeks of the year. Then there are the 12 equally-spaced 100m-high yellow support towers - set out like a clock face to represent time and the 12 months of the year. Whilst you're walking up the sides of The O2 on your experiences, you might not realise it, but the dome is completely round. And it is actually 365metres in diameter, to represent, yes you guessed it, the number of days in the year. You see, architect Richard Rogers was quite clever when it came to his Dome. And now there's no doubting that the big white dome has now become an iconic landmark of London.
