Best for: a colourful cool-off
This impressive courtyard offers an escape from the bustle of King's Cross, and its expanse of playful fountains are just the thing for a hot day. No less than 1,080 fountains create the drama in fashionable Granary Square at Coal Drops Yard. With spurts choreographed to erupt at different heights, children can skip through the water as the jets shoot ever higher, before it all goes momentarily quiet – then the fountains begin to bubble all over again.
