Chicago Architecture Tour: Underground Pedway and the Loop

Chicago hides a second downtown beneath its streets. On this two-hour walk, you’ll follow the Pedway, a patchwork of tunnels, stairs, building passages, and commercial corridors linking parts of the Loop. It is not one polished underground mall. That is exactly what makes the route interesting.

I like the way this tour shows you a side of Chicago that even many locals miss. I also like its practical value: once you learn the signs and connections, you can use parts of the Pedway to get around when cold, rain, wind, or crowds make street-level walking unpleasant.

The main drawback is that the route includes plenty of stairs and some time outdoors. The Pedway can also feel less grand than Chicago’s famous architectural landmarks, so you should choose this tour for its city secrets and expert storytelling, not for a parade of spectacular interiors.

Key points

• A rare look below the Loop: Follow sections of Chicago’s underground walkway system that are easy to miss on your own.
• Small groups of up to 15: The format gives you a better chance to hear the guide and ask questions.
• Strong guide personalities: Guides including Heath, Adam, Kaylee, Hillary, Colleen, Jess, and others bring local stories and architecture details to the route.
• Useful in bad weather: Much of the tour is indoors or underground, making it a good cold-day or rainy-day option.
• More than a tunnel walk: The route includes the Picasso, Macy’s on State Street, Block 37, City Hall access, and possibly the Chicago Cultural Center.
• A moderate physical outing: Expect walking, stairs, and changes between underground and street-level passages.

Why Chicago’s Pedway is worth two hours

Chicago’s Pedway is less a single tunnel than a connected collection of routes beneath and through downtown buildings. Some sections feel like ordinary passageways. Others lead through commercial complexes, civic buildings, or older architectural spaces.

That uneven character is part of the lesson. Chicago’s underground network grew in pieces rather than from one master plan. A guide helps you understand where you are, which signs matter, and how the system connects to the street grid above.

I would not book this as a substitute for one of Chicago’s classic architecture cruises. You will not spend two hours gazing at a continuous row of landmark facades from the river. Instead, you learn how downtown works from the inside, including the shortcuts, stairways, and building links that are easy to overlook.

The tour is especially useful early in a Chicago visit. You leave with a better sense of the Loop’s layout, and you may recognize the Pedway entrances later when you are trying to avoid freezing temperatures or heavy rain.

Starting at 120 North LaSalle Street

The tour begins at 120 N LaSalle Street, in the heart of the Loop and close to public transportation. The location puts you near the civic center of downtown, so you are starting in a part of Chicago where streets, office towers, public art, and government buildings quickly overlap.

From there, your guide leads the group below street level. The opening section sets the tone: this is a walking tour about orientation as much as architecture. Pay attention to the signs and turns. You are not simply being carried from one attraction to the next. You are learning how the system is pieced together.

The group size is capped at 15 people. That matters underground, where sound can carry poorly and a large crowd can easily block narrow passages. A small group also makes it easier to stop for questions without holding up a long line.

Guides vary, but the strongest names associated with this route include Heath, Adam, Kaylee, Hillary, Colleen, Jess, Jessica, and Henry. Their styles differ. Heath is known for an energetic, funny presentation, while Kaylee brings an openly enthusiastic interest in Chicago. One guide used quick drawings on a folder to explain building details, which can be more helpful than a long lecture when you are standing in a confusing passage.

Following the Pedway under City Hall

The first major portion lasts about 45 minutes and takes you through tunnels and stairs beneath several blocks. You may access buildings such as City Hall, where the interior details add a civic layer to the architecture.

This part is valuable because the Pedway is easy to misunderstand from a map. A map can show connections, but it cannot explain the changes in atmosphere, the stairs, the building entrances, or the points where an underground route returns you to the city above.

Your guide also supplies the human context. The best moments on this tour come when a plain corridor becomes evidence of how Chicago handles weather, work, transportation, and crowded downtown life. You learn to look at the city as a working machine, not only as a collection of postcard buildings.

Expect a moderate amount of walking. You should be comfortable on your feet and prepared for stairs. A previous family group with young teens found the route manageable, though it noted the number of steps. Elevators were reportedly an option at points, but you should still contact the operator before booking if stairs are a concern.

Meeting Picasso in the Loop

The next stop is the Picasso, the large public sculpture near the Civic Center. You get a close view before returning below ground.

The sculpture was given to Chicago by Pablo Picasso, and its unusual form makes a useful counterpoint to the orderly streets and formal civic buildings around it. This is a short stop, about 10 minutes, but it breaks up the underground walking and gives you a chance to see one of Chicago’s best-known public artworks at close range.

Your guide can also connect the sculpture to Chicago’s larger tradition of placing ambitious modern art in public spaces. The value here is not simply taking a photograph. It is understanding why a city known for steel, stone, and historic towers also made room for a large, puzzling modern work in a civic setting.

Admission is free. Since this is an outdoor stop, bring a coat in winter and rain protection in wet weather. The tour operates in all weather conditions, but much of its appeal is that the exposed sections are brief.

Entering Macy’s on State Street

The route then reaches Macy’s on State Street, the former Marshall Field’s department store. The Pedway section beneath this building is one of the more atmospheric parts of the route, with a connection to an older commercial side of downtown.

On weekend tours, you may see some of the building’s interior as well. On weekday tours, the exact interior portion changes, and the group skips this particular interior for another one. That difference is worth noting if you are choosing a tour time based on architecture rather than convenience.

The former Marshall Field’s name matters because the building carries Chicago retail history as well as architectural interest. Even if you are not shopping, the stop helps you see how department stores once functioned as major downtown destinations, tied into transportation, offices, and underground routes.

Do not expect a long visit inside Macy’s. The scheduled stop is about 10 minutes. It works best as one piece of a larger story about how the Loop’s buildings connect and how older commercial spaces continue to serve modern downtown life.

Block 37 and the city below the city

At Block 37, the tour enters a large commercial complex through the Pedway and pauses at several favorite spots. This stop also lasts about 10 minutes.

Block 37 shows a different side of the underground system from City Hall and Macy’s. Here, the Pedway functions as part of a modern retail and office environment. You get a practical sense of how underground routes can connect major buildings without requiring every trip to pass through traffic and weather.

For first-time visitors, this may be one of the most useful sections. Downtown Chicago can look simple on a street map, yet its buildings have layers of connections. Once your guide explains the pattern, you may feel more confident moving between the Loop, retail areas, and the streets near Millennium Park.

The commercial sections are not always beautiful. Some corridors may feel functional rather than historic. That is a fair trade for seeing the Pedway as Chicago residents use it, not as a staged attraction.

Weekend access to the Chicago Cultural Center

Weekend tour offerings include the interior of the Chicago Cultural Center, a 19th-century building near Millennium Park. This is a particularly welcome addition because the Cultural Center provides a formal architectural contrast to the plain underground corridors.

The building is known for ornate interior details, and the stop gives you a chance to look upward and slow down after the close quarters of the Pedway. The scheduled visit is about 10 minutes, so it is an introduction rather than a full architectural examination.

If the Cultural Center is important to you, book a weekend departure and confirm the current route when making your reservation. Weekday tours do not include this interior stop, though they use a different interior instead.

This variation is not a flaw, but it does mean the tour is not identical every day. The basic Pedway experience remains the focus, while certain interior views depend on the schedule.

The secret final section and the walk to Aqua

The published route keeps one final portion undisclosed. That promise adds a little fun, but it also means you should not plan your day around a precise list of every building you will see.

The tour ends at Aqua, 225 N Columbus Drive, just north of Millennium Park. That is a useful finish. You are well placed for Millennium Park, the lakefront, nearby museums, and more downtown walking.

The point-to-point route also means you do not finish where you started. If you parked near the beginning, allow time to return by public transportation or on foot. The end location is close to central attractions, so most people can continue sightseeing rather than making a special trip back to LaSalle Street.

What the guide adds to the architecture

The Pedway itself is the hook, but the guide makes the experience worthwhile. A good guide explains not only what a building is, but why its details matter and how it fits into the city around it.

That strength comes through in the range of guide styles. Adam is described as funny and proud of Chicago. Heath combines humor with a large store of city stories. Kaylee brings warmth and enthusiasm, while Colleen is especially strong on both the Pedway and the architectural points along the route.

One guide worked for the architectural company that built the Salesforce building and used sketches to explain subtle features. That sort of visual aid can be useful for people who enjoy architecture but do not have a technical background.

The quality of any small-group tour depends partly on the individual guide. Nearly all the supplied feedback describes energetic, clear, and informed leaders, but one December experience involved a guide who behaved unusually and failed to provide context. The company apologized, refunded the booking, and described it as an isolated incident. I would treat that as an exception, but it is still fair to remember that the guide is central to this experience.

Is $35 a good value?

At $35 per person, this is a reasonable price for about two hours with a local guide and a maximum group of 15. You are paying for orientation, access to a route that is difficult to understand alone, and stories that turn ordinary corridors into part of Chicago’s urban history.

The value is strongest for people who care about architecture, city planning, local history, or practical navigation. It is also a smart choice on a bitterly cold day. Several recent outings took place during severe winter conditions, including temperatures far below freezing, and the largely indoor route provided a way to see downtown without spending the whole afternoon outside.

The value is weaker if you want a grand visual show from start to finish. The Pedway includes commercial passages and functional corridors. Some people may find the underground sections plain, especially if they expected a polished attraction.

Think of the ticket as payment for access and interpretation, not for admission to a major museum. The Picasso and the main public areas cost nothing to enter, while the guide gives those places meaning and helps you find them.

Who should book this Chicago tour?

I would recommend it to:

• Architecture fans who want something beyond the usual river route
• Chicago residents who think they already know downtown
• First-time visitors who want practical Loop orientation
• Families with older children or young teens who can handle stairs
• Anyone planning a cold, rainy, or windy day in the city
• People who enjoy local stories and unusual urban details

You may want another tour if your priority is a long list of famous buildings, extensive time inside landmark interiors, or a fully outdoor sightseeing route. You should also consider your comfort with stairs, underground passages, and a changing route.

Dress for the weather even though much of the tour is indoors. You will spend some time outside at the Picasso and moving between buildings. Comfortable shoes are essential, and a moderate level of fitness is expected.

Final call: book it for access, stories, and city smarts

Book this tour if you want to understand Chicago from a less obvious angle. The best payoff is not one single landmark. It is the feeling that you now know how the Loop is connected below the streets, and that you can use that knowledge on your own.

At $35, the small group, local guide, and unusual route make it a good buy for architecture-minded visitors and curious locals. Choose a weekend if the Chicago Cultural Center interior matters to you, and leave room in your day after the tour for Millennium Park and the nearby lakefront.

Skip it only if you want nonstop landmark interiors or a grand outdoor panorama. For everyone else, this is a practical, odd, highly local way to spend two hours in central Chicago.
