I was pretty late to the party catching a ride on this but it was worth the wait. And, yes, there was a slightly tedious wait with a fractious baby in a stroller. I plan to get back there at a less crowded time. Once it gets started all those frustrations are forgotten though. The UK's first urban cable car, it was opened just in time for the London Olympic Games in 2012. It provides unique views of City Airport and the financial district with highlights including the Gherkin as well as Canary Wharf and Europe's tallest skyscraper, the Shard.
A helpful commentary talks you through key spectacles and history as you travel along. You get a great big souvenir "ticket" too. It is all very well done.
I suffer from vertigo and the children are often wary of heights but we all enjoyed the experience and couldn't stop looking out at the 360 degree panorama around us. Greenwich was a particular highlight, with the Old Royal Naval College and the Royal Observatory looking just as spectacular as they do from the ground. Seven year old Electra was completely fascinated by the ArceloMittal Orbit, AKA the UK's tallest sculpture or, more to the point for Electra, the longest, tallest and fastest slide in the world. Guess that's up next in terms of London attractions...!
