London: The Lost Tunnels of Euston Station Guided Tour

Euston’s working Tube station has a forgotten side: dusty tunnels and sealed passageways that once carried the public. This 75-minute walk takes you into that lost network, past old posters and a secret ventilation shaft where you can look down on Victoria line trains.

I like the small-scale feel, which gives your guide room to explain the station’s changes and let you take photos. I also like the link between old London and new London, from the early station on Melton and Drummond Streets to the coming HS2 terminus. The drawback is clear: low light, stairs, uneven ground, and tight spaces make this a poor choice if you have mobility limits or feel uneasy underground.

Key points to know before you book

• Old Euston beneath the modern station: Walk through disused spaces once used by the traveling public.
• Vintage posters still on the walls: See advertising remnants hidden from view for more than 50 years.
• A view of Victoria line trains: Reach a ventilation shaft and look down into the active railway.
• A story of change: Connect Euston’s early Tube years with its planned role as the London end of HS2.
• A proper walking tour: Expect stairs, uneven ground, low lighting, and no toilets.
• Best for curious adults and older children: Children must be at least 10, and each adult may bring no more than four children aged 10 to 15.

Entering Euston’s forgotten underground network

The tour begins at Euston Square station, not at the main Euston railway station. Meet your guide at the south exit on the corner of Gower Street and Gower Place, NW1 2BF. Look for the entrance with the glass façade on the hospital side of Euston Road. There is more than one station entrance, so this detail matters.

From there, your English-speaking guide leads you toward the disused parts of the station. The experience is not a standard Tube ride or a museum display behind glass. You walk through spaces that have lost their daily purpose, with the station’s working network still close by.

That contrast gives the tour its appeal. Above ground, Euston is a busy transport point. Below it, old corridors and passageways offer a quieter record of how London moved around the city. The route is short in time but dense in atmosphere, with 75 minutes spent walking, listening, and looking carefully at details you would normally pass without knowing they were there.

The pace depends on the group and the guide, but the tour is designed as a guided walk rather than a race from one stop to another. Scott and Anthony are among the guides who lead this experience. If one of them is guiding your visit, expect plenty of explanation and time for photographs based on the way this tour has been run.

Melton Street, Drummond Street, and Euston’s early years

The story begins with Euston’s humble origins around the corner of Melton and Drummond Streets. That starting point helps place the station in a very different London, before the modern transport complex took its present form.

Your guide explains how the Tube station grew and changed, then ties those changes to the spaces around you. This is useful because old tunnels can otherwise look like a string of dark walls and dusty floors. The historical context gives each corridor a purpose and helps you picture the traveling public that once used it.

I especially like this part for visitors who already know London’s famous sights. You are not simply checking off another attraction. You are learning how a familiar transport hub developed, and why parts of it were later closed or altered.

The tour also shows the remains of Leslie Green station architecture and its surroundings. Leslie Green stations are associated with distinctive early Underground design, and seeing the surviving elements in their original setting gives the architecture more meaning than a photograph alone.

Do not expect a polished architectural tour with every room restored. The charm comes from the worn state of the place. These are working remnants and disused areas, not newly decorated galleries. That means some details may be subtle, dusty, or partly concealed, so listen closely and take your time looking.

Vintage posters hidden for more than 50 years

One of the most rewarding details is the collection of old advertising remnants on the walls. Some vintage posters have been concealed from public view for more than five decades.

You may not see every poster in perfect condition. That is part of the point. Age, dust, and layers of later construction are visible. The fragments show how the Underground once sold more than transport. Its walls carried advertisements and messages that belonged to earlier decades of London life.

I like these scraps because they make the station feel personal. A grand transport system can seem impersonal when you only use it to get from one stop to another. Old posters return a human scale to the place. They suggest the ordinary passengers who waited, walked, and read the walls while making their way across London.

Bring a camera if you want photographs, but do not let photography take over. The passages are dark, and the guide’s explanation is a major part of the experience. The small groups reported on this tour can help here. One group had only four people, which allowed a quieter visit and made it easier to pause for pictures. Larger groups may feel less intimate.

Dark passageways, stairs, and the practical side of the walk

The route takes you through a labyrinth of dark and dusty passageways. You will walk on uneven ground, move through low-light areas, and use stairs. Comfortable shoes are essential, and comfortable clothing is a sensible choice.

The conditions are not a surprise, but they can still affect your enjoyment. If you like the idea of an old underground space but dislike confined areas, this tour may feel stressful rather than exciting. It is not suitable for people with claustrophobia or mobility impairments.

Open-toed shoes are not allowed. Food and drinks are also not allowed inside the tour area, and large bags or luggage should be left behind. There are no toilets during the experience, so use facilities before meeting the guide.

You should also dress for the weather because you meet outdoors at Euston Square. The underground sections may feel different from the street, but weather-appropriate clothing remains the practical choice for the start and end of the visit.

The tour finishes back at the meeting point. That makes it easy to continue around central London afterward, but remember that the experience is a walking tour. The 75-minute duration does not include time spent getting to Euston Square or making onward travel plans.

Looking down on Victoria line trains

The ventilation shaft is one of the tour’s most unusual moments. From this concealed point, you look down on Victoria line trains moving below.

This stop connects the abandoned and active parts of the Underground in a single view. Old passageways sit beside a railway that still carries passengers, and the contrast makes the station’s layered design easier to understand.

It also shows why a guided visit matters. A shaft, opening, or blocked corridor can be easy to overlook if you are on your own. Your guide explains what you are seeing and how it fits into the wider station network.

The view may be brief, and it is not the same as standing on a platform watching trains arrive. Its value comes from the angle and the setting. You are seeing an active line from a place normally kept away from public movement.

Keep in mind that the route remains dark and involves stairs. If you need a fully comfortable viewing area or an accessible route, this will not be the right experience for you.

From old Tube station to future HS2 terminus

Euston’s past is only half the story. The tour also explains how the station is set to change with the arrival of High Speed 2, or HS2, the planned high-speed rail line linking London with the Midlands.

The point is not simply that a new railway is coming. The planned work affects the station’s shape, use, and surroundings. You hear how Euston is expected to become the London terminus for HS2 and how the station’s older features may be swept away or altered.

That gives the tour a sense of urgency. You are not looking at an abandoned place with no connection to modern London. You are seeing part of a transport site in transition, where earlier layers may disappear as newer infrastructure arrives.

The station serves more than 42 million passengers each year. That figure helps explain why Euston has been repeatedly rebuilt and improved. A station serving that many people cannot remain frozen in its early form. The tour lets you consider the cost of progress, including what may be lost when major transport projects reshape an old site.

I find this historical and future-focused balance more useful than a tour that only celebrates the past. You get the old posters and Leslie Green details, but you also learn why Euston keeps changing.

How much value do you get for $60.61?

At $60.61 per person, this is not a cheap Tube outing. The value depends on what you want from a London tour.

If you are looking for a broad introduction to London transport, your money may go further elsewhere. This is a focused 75-minute experience in a restricted part of one station. You are paying for access, a specialist subject, and a guide who can explain details you could not reach on an ordinary journey.

I think the price makes the most sense for visitors who have already seen London’s main sights, enjoy transport history, or want an unusual activity away from the usual museum circuit. The tour is also a good fit for people who value a small group and direct contact with a guide. Scott and Anthony, for example, have been praised for being friendly, informative, and willing to allow time for photographs.

The tour is written by historical experts from the London Transport Museum and draws on the Museum’s archive and collection. That gives the route a solid research base, while the physical spaces keep it from feeling like a lecture.

Free cancellation up to 24 hours before the tour and the option to reserve now and pay later reduce some booking risk. Still, check the available starting times before you plan the rest of your day. The activity runs in English only, and the price does not change the basic physical demands of the route.

Who will enjoy this Euston tour most?

I would choose this tour if you enjoy old infrastructure, London transport, urban change, or places usually closed to the public. It suits curious adults and children aged 10 and older who can manage a full walking route with stairs and uneven surfaces.

It also works well for repeat visitors to London. You may have used Euston many times without realizing how much of the station lies outside the normal passenger route. This experience gives a familiar location a new layer.

Families should plan carefully. No more than four children aged 10 to 15 are allowed per adult, and children under 10 cannot join. The low lighting and rough surfaces may be tiring for younger children even if they meet the age requirement.

I would skip it if you need step-free access, dislike confined spaces, want a relaxed seated activity, or are carrying luggage. The restrictions are not minor details. They shape the whole experience.

Simple ways to prepare for the meeting point

Give yourself extra time to find the correct Euston Square entrance. The meeting point is at the south exit on Gower Street and Gower Place, with the glass façade on the hospital side of Euston Road. The what3words location is baked.bend.worry.

Wear closed, comfortable shoes and clothing that allows easy movement. Do not bring large bags, food, or drinks. Carry identification, since a passport or ID card is listed among the items to bring.

Arrive ready to spend the entire 75 minutes on foot. There are no toilets on the route, so plan ahead. Since the activity ends where it begins, you can arrange your next stop from Euston Square without needing to cross the city first.

Should you book the Lost Tunnels of Euston Station?

Book it if you want a short, specialized London experience that combines old Tube spaces, surviving posters, early station design, and the future HS2 project. The ventilation shaft view of Victoria line trains adds a rare working-railway perspective, while the guide turns dusty corridors into a story about how London moves.

Skip it if you are uncomfortable with darkness, stairs, uneven ground, or enclosed passages. At $60.61, the tour rewards genuine interest in transport history more than casual sightseeing.

For the right visitor, this is a memorable way to see Euston before its next major transformation. Check the starting time, wear proper shoes, and arrive at the correct Euston Square entrance. Those small steps make a big difference.
