Illuminated flotilla of 150 decorated boats, including the Queen’s own barge, Gloriana, as part of the Thames Festival. The procession will travel at dusk from Chelsea to Tower Bridge, with the aim of creating a ribbon of light reflected across the water. All participating crews are raising funds for the RNLI, to support the construction of a new lifeboat station at Waterloo Bridge.
Exact departure times to be confirmed closer to the date. Sunset is at 7pm, so likely to be around that time though to give the boats time to get to Tower Bridge.
Good news as there are hardly any disruptions on the London Underground on that Saturday evening, and none in Central London.
The bridges, lit up by Illuminated River, will be threaded with tones of platinum and purple in a synchronized flow of subtly moving LED lights across nine central London Thames bridges, from Lambeth to London Bridge.
