Part 2 of my walking video that started in the Woolwich Foot Tunnel. I pass the Thames Barrier ruminating on how tenuous London’s grip is on the solid ground we take for granted when the rising waters of the Thames could reclaim the City …. and one day will. Oddly, I find this a comforting thought.

Despite it being a sultry, cloudy day I could appreciate the narrative arc of re-crossing the Thames on the Air Line Cable Car from Greenwich to Royal Docks. If I was honest, I was a tad disappointed with the experience – when something arrives with such corporate fan fare you’re entitled to expect to have your mind blown. But as the cable car glides to its summit mid Thames look southwards to the highlands of the ridge of land running from Greenwich to Belvedere and from there are views that will truly twist your melon.
