Embankment

Walk through the hidden world under London's streets.

Walk inspired by the teen wizard.

A walk around eccentric London landmarks.

A walk following the adventures of the detective from Strand's gas-lit alleys to Covent Garden with its Opera House.

A walk around the National Gallery with a focus on the work of Rembrandt, Rubens, Leonardo da Vinci, Van Dyck, Goya, Constable, Turner, Monet, Renoir and Van Gogh.

Spooky walk around the alleyways and church yards of the embankment with a pit stop at a haunted pub.

Paranormal stroll around the dark corners of the West End.

Murderous stories on this walk.

Start with an eye-popping panoramic of London and its river, a change-the-way-you-see-it moment in Trafalgar Square, to a hidden Georgian alleyway, street performers, the Walk of Fame, the oldest theatre and raising a glass with the orchestra of the Royal Opera House.

A goulash of a walk through hidden streets.

Photographers call it light-painting. It's what makes a great city so magical at night. It's the difference between seeing a stage-set under ordinary house lights and seeing it "live", seeing it when the show's blazing away. Now some context. I wrote this on a grey September afternoon. I was on the roof of the National Theatre, looking out across the river at Somerset House, Waterloo Bridge, Cleopatra's Needle, Charing Cross Station, Whitehall Court, the Embankment, St. Martin-in-the-Fields, Covent Garden, etc. I was looking, in short, at this walk's "stage". And it looked pretty good - maybe a bit monochrome - but pretty good. But if it's pretty good in the even light of day, it's sensational at night. Vivid, light-sprinkled, colour-saturated, purple-shadowed, transformed old London! Reason enough for coming here at night. But to come here on this walk is to go one better: having to do - as always - with a surprise-laden, marvel-crammed route and the way the history we'll encounter lights things up from within.
