Under London Tours: 7 Ultimate Secrets Revealed
Experience London’s Depths with London Sightseeing Taxi Tours
London’s famous skyline—from the stately dome of St Paul’s Cathedral to the shimmering shard of glass that is The Shard—tells only half the story of Britain’s capital. Beneath the streets lies a labyrinth of forgotten rivers, wartime bunkers, ancient crypts, and subterranean marvels that most visitors never see. Under London Tours reveal these hidden layers, and no one delivers the journey quite like London Sightseeing Taxi Tours. Operating classic black cabs staffed by knowledgeable, fully licensed driver-guides, we bring history to life while wrapping you in the comfort and flexibility of a private vehicle. Got a whole weekend? Pair your underground adventure with our popular 2-day London itinerary for the ultimate city immersion.
Why Choose Under London Tours with a Black Cab?
Unlike group coaches or rigid walking itineraries, our black-cab adventures weave seamlessly through traffic, stop at unpublicised entrances, and plunge into stories you would otherwise miss. With room for up to six guests, climate control, and panoramic glass roofs, you can soak up every dramatic reveal across a single seamless narrative. If you prefer surface icons first, consider our flexible Explore London in One Day package, then dive beneath the pavement after lunch. Most importantly, an Under London Tours experience is fully customisable—pause for photos, linger for a pint in a vaulted pub, or ask for additional secrets on the fly. We operate 24/7, so night-owl history buffs can explore torch-lit tunnels long after regular museums close.
Under London Tours — What Lies Beneath?
At its heart, an Under London Tours itinerary explores the capital’s hidden infrastructure and forgotten spaces. Think 2,000-year-old Roman amphitheatres, the clink of medieval prisons, Churchill’s top-secret Cabinet War Rooms, and the eerie disused stations of the world’s first underground railway. Our expert guides chronicle engineering feats, political intrigue, and hair-raising legends while steering you safely through dimly lit passages. Every twist and turn heightens your appreciation for modern London’s resilience and invention. Want photographic proof?
