The cable car runs for about 1.1km across the river on three mighty towers, amost 100m at the peak. It is a brilliant piece of engineering, the views are fantastic and great value. I highly recommend this newest landmark in London. As you will see from the video it was a wet and cloudy day in London (July 10). I can only imagine how spectacular it would be on a fine, clear day. The sightline must cover miles of the city. Deails from this website of how to get there and times.
