Night Carnival, Thames Festival, Waterloo

This twilight parade of dancers, musicians, horseback cavalry and street performers starts near the National Theatre, heads north over Blackfriars Bridge and west along Victoria Embankment, finishing by Victoria Gardens. Should be a good night in central London if you’ve missed the daytime events.
