London is huge. I mean, it’s galactically flipping enormous. You need to get your tiny mind around this as young as possible, to know that there is endless wonder in this city. The best way to do this is with Up at The O2, who’ll help you clamber over the mighty venue. It’s pretty steep for little legs, but no pain, no gain, kids. Oh, and you’re clipped on, so you won’t slide off into the river or anything. Once on top, gaze at the towers of the City, the Thames rolling towards its estuary, the hills rising to the north and south and London stretching westwards, for ever.
Ages 9-plus and a minimum of 1.2m tall. From £30.
