Are you looking for a slightly different view of London? Although many of the city’s most notable sites are above ground, you will find that there is a lot of history, remarkable works of engineering, and stories to be told, underneath the Earth.

In an underground tour of London, you can walk behind the scenes of the oldest metro in the world, take a quick peek into former air-raid shelters used during the second world war, and walk the dusty passageways that were once used by former British Prime Minister, Winston Churchill.

If riding in black cabs and queuing at Madame Tussauds is not your thing any more, then try looking below the surface to escape the crowds.

To help you out, I’ve listed some of my favorite underground London tours that take you through lost tunnels and uncover parts of London you didn’t know were there.

The Best Underground London Tours

You’ll discover a hidden world of secret tunnels, terrifying tombs, elaborate train routes, and ancient cave systems on one of these underground London tours.

1. Cabinet War Rooms

Immerse yourself in the atmosphere of the Blitz with a trip down into the historic Cabinet War Rooms.

This warren of tunnels and bunkers under Whitehall was the headquarters for Britain’s war effort during WW2.

The tour starts by exploring the War Cabinet Room from where Winston Churchill planned Britain’s next move.

You can actually see the chair (complete with scratch marks on its arms) which he used during highly stressful meetings.

In the Map Room, nothing has changed since 16 Aug 1945, when the lights were finally switched off.

Wartime maps, colour-coded telephones, and even rationed sugar cubes remain exactly as they were when the war ended.

2. Chislehurst Caves

This network of 8000-year-old caves in the greater London area is an unexpected treat. The caves, which extend for 20 miles, were initially created as a result of flint and chalk mining.

You can take a lamp-lit tour deep into this labyrinth and explore the caves’ varied history; from their origins as mines to their subsequent use as an ammunition depot and then as an air raid shelter during WW2.
