London: The Lost Tunnels of Euston Station Guided Tour

Euston Underground station has a public face of tiled corridors, ticket barriers, and hurried commuters. Below and beside that everyday system sits a far stranger world: disused tunnels and dusty passageways that once served passengers and now offer a glimpse into London’s changing Tube network.

I like two things in particular here. First, you see physical leftovers, including vintage advertising posters hidden for decades. Second, the tour connects old Euston with its future as the London terminus for HS2, giving the walk a useful sense of change rather than treating the station as a museum piece.

The main drawback is the setting itself. This is not an easy stroll. Expect stairs, uneven ground, low light, and confined spaces, with no toilets during the 75-minute visit. If you dislike enclosed places or have mobility problems, choose another London tour.

Key points to know before booking

• The meeting point is Euston Square, not Euston station: Find the south exit with the glass façade on the hospital side of Euston Road.
• You walk through real disused Tube spaces: The route includes dark passageways, old public areas, stairs, and uneven ground.
• Vintage posters remain on the walls: These advertising fragments provide some of the tour’s most striking visual reminders of earlier London.
• The ventilation shaft offers a working Tube view: You look down toward Victoria Line trains from a hidden part of the station.
• The story reaches into the future: Your guide explains how HS2 is expected to reshape Euston.
• The tour suits curious adults and older children: Children must be at least 10, and no more than four children aged 10 to 15 may join per adult.

Meeting your guide at Euston Square

Your starting point is easy to get wrong because the names are similar. The tour begins at the south exit of Euston Square station, on the corner of Gower Street and Gower Place, postcode NW1 2BF.

Look for the entrance with the glass façade on the hospital side of Euston Road. There is more than one entrance to Euston Square, so allow a few extra minutes to get your bearings. The what3words location is baked.bend.worry, which can help if you are already using that app.

The tour ends back at the same meeting point. That makes the outing simple to fit into a day of sightseeing, though you should not confuse Euston Square with the larger Euston Underground and railway station nearby.

An English-speaking live guide leads the walk. Guides such as Scott and Anthony have been praised for giving clear explanations, keeping the mood friendly, and allowing time for photographs. The group size can affect the feel of the visit. A very small group, such as four people, gives you more room and makes it easier to ask questions. A larger group may feel less intimate in narrow passageways.

Entering Euston’s earlier underground world

The tour begins with the station’s past, including its modest beginnings near Melton and Drummond Streets. That detail helps put modern Euston in perspective. Today, the area handles more than 42 million passengers each year across its Tube and railway connections, but the station did not start out as one of London’s major transport hubs.

From the ordinary station entrance, your guide takes you toward parts of the network no longer used by the public. The appeal is not polished decoration. It is the sense of seeing infrastructure after its working life has ended.

You follow a route through dark and dusty passageways that once carried passengers. The surfaces and lighting are part of the experience, but they also explain why sturdy shoes and sensible clothing matter. This is a walking tour in a working transport environment, not a comfortable gallery with wide floors and bright displays.

The wording may suggest a large underground labyrinth, but the visit lasts 75 minutes, so the route is focused rather than endless. You will see selected disused spaces and hear the story that links them. Your guide does the work of pointing out what matters, since an old wall or blocked corridor can look unremarkable without context.

Vintage posters hidden behind modern London

One of the best reasons to book this tour is the chance to see remnants of old advertising posters concealed from public view for more than 50 years. These fragments are not presented as pristine works of art. Their worn condition is precisely what makes them useful.

A poster behind a later wall or station surface can reveal how London’s transport spaces changed over time. It also gives you something concrete to look at while your guide explains the station’s earlier layout and use.

I would not book this expecting a large collection of complete advertisements. The attraction is the unexpected survival of pieces in places most passengers never see. Take your time with them and listen to the explanation around each area. Photographs are allowed, and the guides give participants time to take them.

The underground setting also changes how you read the posters. In a museum, a vintage advertisement has been removed from its original surroundings. Here, the surrounding tunnel helps you picture the people who once passed by it on their way to a train.

A glimpse at the Leslie Green station design

The tour also brings attention to an iconic Leslie Green station and its surroundings before they are swept away by planned changes. Leslie Green stations are associated with their distinctive early Underground architecture, so this part adds an architectural layer to the walk.

The most important point is that you are not seeing Euston as a single, fixed building. Stations are repeatedly altered, closed, redirected, and rebuilt as passenger needs change. The old spaces show the cost of that process in a way that a standard Tube ride cannot.

Your guide explains what has disappeared, what remains, and why some corridors were no longer needed. That makes the visit useful for anyone interested in the history of public transport, urban design, or the practical problems of keeping an old station working.

Do not expect every historic feature to be perfectly visible. Lighting is low, some areas are dusty, and the walk includes uneven surfaces. The reward comes from noticing small details that would be easy to miss without a guide.

Looking down on Victoria Line trains

A highlight of the route is a secret ventilation shaft where you can look down on Victoria Line trains. This is a sharp contrast with the abandoned spaces around it. One part of the station is quiet and unused, while the railway below remains an active piece of London’s daily transport system.

This view helps you understand that a Tube station is more than platforms and ticket halls. Behind the public route are ventilation systems, service areas, abandoned corridors, and structural spaces that keep the railway functioning or preserve traces of its earlier design.

The shaft is also a good reason to pay attention to your guide’s instructions. The route includes stairs, low lighting, and areas that are not designed for casual public access. Stay with the group and take care with your footing.

The exact atmosphere will depend on the group and the timing of your visit, but the setting gives the tour a strong sense of place. You are not simply hearing about old Euston. You are standing inside a part of it that most people pass without knowing it exists.

How HS2 changes the story of Euston

The tour is not only about abandoned tunnels. Euston is set to change with the arrival of High Speed 2, which is planned to make the station the London terminus for the line to the Midlands.

That future matters because it puts the old passageways in a wider story. London transport stations are built, altered, and sometimes erased to make room for new routes and larger passenger flows. At Euston, the past and the planned future occupy the same space.

Your guide explains the latest innovations affecting the Tube and Network Rail station. You get a sense of how a historic transport site must adapt while continuing to serve millions of passengers.

This forward-looking part may appeal less to someone who wants only abandoned tunnels, but I think it improves the tour. Without it, the walk could feel like a collection of old corridors. With it, you see why the station’s old spaces matter now, before major changes alter the area again.

The tour does not present Euston as frozen in time. It shows a station in transition, with its old architecture, working railway, and planned HS2 role all connected.

What the 75-minute format feels like

At 75 minutes, this is a compact experience. You can fit it between other London plans without giving up half a day, but the short format means the guide must keep the route moving.

You will spend much of the visit walking, including stairs and uneven ground. There is no toilet stop, and food and drinks are not allowed, so use facilities before you arrive. Large bags and luggage are also not permitted. Bring only what you can carry comfortably.

Wear closed, comfortable shoes. Open-toed shoes are not allowed, and lightweight city footwear may not be pleasant on rough surfaces or stairs. Comfortable clothes and weather-appropriate clothing are sensible because the meeting point is outside and conditions may vary before you enter the station areas.

The low lighting is not a minor detail. If you find dark, enclosed spaces uncomfortable, the atmosphere may outweigh the historical interest. This is also not suitable for people with mobility impairments, since the route involves walking up and down stairs and crossing uneven ground.

Children under 10 cannot join. For children aged 10 to 15, there can be no more than four children per adult. Older children with an interest in transport may find the experience memorable, but parents should explain in advance that this is a dark, physical walk rather than a standard sightseeing tour.

Is the $60.61 price fair?

At about $60.61 per person, the tour is not a cheap way to fill an hour in London. You are paying for access to a place you cannot explore on your own, along with a guide who supplies the historical and technical context.

The value depends on what you want from London. If you are mainly looking for famous views, grand interiors, or a long list of landmarks, the price may feel high for 75 minutes. You could spend less on a regular Tube journey and see more of the city above ground.

If you enjoy transport history, unusual architecture, or places normally closed to the public, the calculation looks better. The tour gives you a focused route through disused spaces, surviving posters, a ventilation shaft, and a station facing major redevelopment. It also saves you from trying to interpret dark corridors without knowing what they were used for.

The London Transport Museum creates the Hidden London tours with historical specialists and material drawn from its archive and collection. That connection matters because the experience is more than a theatrical walk through an old tunnel. The tour has a clear research base and links the physical spaces to London’s wider transport story.

The booking terms also reduce some risk. You can cancel up to 24 hours before the tour for a full refund, and you can reserve now and pay later. Check the available starting times before building the rest of your day around it.

Who will enjoy this Euston tour most?

I would recommend it to you if you like:

• London transport and Tube history
• Abandoned or disused urban spaces
• Old advertising, architecture, and station design
• Guided walks with a strong sense of place
• Seeing how old infrastructure connects to future building plans
• Short activities that fit into a busy sightseeing schedule

It is especially good for returning London visitors who have already seen the main attractions. Euston is familiar to many people as a place to change trains, but this tour offers a different way to understand it.

It is less suitable if you want a relaxed, level walk or a broad tour of central London. The route is concentrated in and around one station, and the physical conditions are part of the experience. Claustrophobia, reduced mobility, or discomfort with stairs should be taken seriously.

The guides appear to be one of the strongest parts of the visit. Scott and Anthony have been noted for friendly explanations, interesting information, and giving people time for pictures. That combination matters in a space where the guide’s storytelling helps you make sense of what you are seeing.

Should you book the Lost Tunnels of Euston tour?

Book this tour if you want London’s transport system at close range, including the parts hidden behind the normal passenger route. The best moments come from the contrast between old and active Euston: worn posters beside modern station use, abandoned passageways beside Victoria Line trains, and historic design beside the planned HS2 changes.

Skip it if you dislike enclosed spaces, need step-free access, or prefer a longer sightseeing tour with many separate landmarks. For the right audience, $60.61 buys a rare look at a working station’s forgotten corners and a clear explanation of why those corners may not survive future redevelopment.
