This October, London Transport Museum’s Hidden London programme will be running its first-ever Halloween tour at Clapham South’s deep-level shelter, Clapham South: Ghosts of the Underground, with tickets now available to book.
Featuring access to some parts of the shelter not previously opened to the public, the new tour combines newly researched wartime stories with exclusive recorded interviews from current and former London Underground staff, who share personal accounts of unusual experiences from across the network.

Hidden London is the museum’s award-winning programme of exclusive guided tours which takes visitors aged 10 and over into closed-off parts of the underground network, including disused stations, wartime shelters and secret filming locations. This new tour is the first Halloween-special to be launched since the programme began in 2015.

On the tour, guests will be led by expert guides eleven floors beneath the streets of south London into the maze of corridors that make up Clapham South’s deep-level shelter. Completed in 1944, the shelter was one of eight constructed beneath London during the Second World War to protect civilians from air raids and could accommodate around 8,000 people.

Today, its near mile of deserted frozen-in-time tunnels, former sleeping quarters and wartime spaces make it one of the most atmospheric and eerie locations in London.

Entering through an entrance not used on the regular Hidden London tour of the shelter, Clapham South: subterranean shelter, the new Halloween tour will explore some areas of the shelter not previously seen by the public. As the tour unfolds, newly uncovered stories from the Second World War will reveal the harrowing first-hand experiences of Londoners who sought refuge across the network during some of its most challenging moments.

These historical accounts will be interwoven with exclusive recorded interviews of current and former London Underground staff, who will share personal recollections of their unusual experiences while working beneath the city, including unexplained sounds, unexpected sightings and other experiences that have remained with them long after they occurred.

Alongside these contemporary testimonies, the tour will also explore some of the Underground’s most enduring stories and legends, including the stories passed between generations of railway staff and commuters.

As guests journey deeper into the shelter, different chapters of history will begin to overlap through atmospheric lighting, sound, projections and immersive storytelling, blurring the line between past and present. Voices from different eras will intersect, familiar details will reappear in unexpected ways, and connections will start to emerge between the people who once sheltered underground, those who work beneath London today and the seemingly deserted shelter of today.

Designed especially for Halloween, the tour is written primarily for adult audiences but is open to visitors aged 10 and over.

The new Clapham South: ghosts of the Underground tour will run four times a day, Wednesday to Sunday from 21 October to 1 November 2026. Prices start from £39 for adults and £36 for concessions/children. The minimum age to attend is 10.

Tickets include half price one-day entry to London Transport Museum in Covent Garden (just 25 minutes away from Clapham South station), where under 18s go free, within a month of the tour date and 10% discount on all full-priced products at the museum shops.
Tickets are now available to book here: ltmuseum.co.uk/hidden-london.

London Transport Museum also has 10 other in-person Hidden London tours in total on offer, which run all year around. This includes tours of the disused Tube station Aldwych, of the closed Jubilee line concourse of Charing Cross, secret parts of Green Park and Baker Street, and the closed platforms of Holborn. Also on offer is an above ground walking tour covering the area around Covent Garden. Tours run all year around Wednesday to Sunday, with locations varying week to week. Tickets are currently available running up until March 2027.

Profits from the tours are used to fund London Transport Museum’s charitable work and to conserve and share London’s transport and design heritage.
