The Chicago Pedway

A roughly five-mile network of underground tunnels, skybridges, and concourse-level corridors connecting more than fifty buildings across the Loop and a few blocks south. It includes City Hall, Macy's, Millennium Station, the Cultural Center, Daley Plaza, Block 37, and dozens of office towers. Built incrementally since the 1950s to let workers move between buildings without going outside in winter. Free to walk, mostly indoor, operated as a partnership between the City of Chicago and the private buildings it passes through.

Yes, especially in winter. The Pedway is interesting on its own but underwhelming without context — you walk past stained glass, mosaics, and Marshall Field's-era murals without realizing what you're seeing. A $35 guided tour pays for itself in stories. The exception: if you're a confident urban explorer who likes museums without audio guides, the free Chicago Detours map is sufficient. Book a guided tour for your first visit; self-guide on return trips.

Inside Chicago Walking Tours' Pedway tour, rated 4.88 across 558 Viator and Tripadvisor reviews (September 2026). Inside Chicago Walking Tours' Pedway tour can be booked on GetYourGuide or direct on insidechicagowalkingtours.com. On GetYourGuide it is listed as Chicago: Underground Pedway & Downtown Secrets Walking Tour (id 414815, $35, 2 hours). Direct, the company sells "Open Your Eyes: Underground Pedway & Other Secrets of the Loop" (daily, $35 adult, capped at 20 guests).

Yes. The Pedway is free and open during normal hours (7am to 5pm, Mon–Fri, with weekend access varying by section). Print the free Chicago Detours Pedway map before you go — it marks every stairway and building entrance. A self-guided loop takes 45 to 90 minutes. The Cultural Center → Macy's → Millennium Station spine is the easiest first-timer route.

Yes — it's a public-use system through public and private buildings. You only pay if you book a guided tour ($35 for the Inside Chicago daily tour) or stop at the food courts, cafés, or shops along the way. The Chicago Detours self-guided map is also free as a downloadable PDF.

Roughly five miles total, connecting more than fifty buildings. Not a single continuous tunnel — a branching network with multiple spines, several dead-ends, and segments that require crossing a lobby to re-enter. A guided tour walks about 1.5 miles of the most interesting sections in two hours. A self-guided spine walk covers about a mile in 45 minutes.

Partially. Standard hours are 7am to 5pm, Mon–Fri. On Saturday and Sunday, many segments close because the office buildings they pass through are closed. The Cultural Center → Macy's → Millennium Station spine generally stays open; obscure office-tower segments (Pittsfield Building, several skybridges) often do not. Confirm hours by emailing Pedway@CityofChicago.org if you're going on a weekend.

Honestly, no, not as your primary activity. In summer you can walk the same Loop above ground in the sun, and the indoor differentiator doesn't matter. Save it for winter. If you only have summer dates, pair a river cruise with a short self-guided Pedway taster.

The Pedway is the public pedestrian network — five miles, fifty buildings, open during business hours. The freight tunnels are a separate, mostly forgotten system of roughly 60 miles of narrow-gauge tunnels built under the Loop in the early 1900s for freight delivery. They flooded in 1992 (the Chicago Loop Flood), have been sealed since, and are not publicly tourable. Any tour offering freight-tunnel access is either a scam or unsafe.

A few — but not where you want them. Macy's lower level, the Cultural Center, and the Block 37 atrium all have restrooms. Beyond those, restrooms are scattered through office-building lobbies and not always available to non-employees. Plan to pass one of the three main anchors every 30 to 45 minutes. On the Inside Chicago tour, your guide knows the stops.

Mostly yes, with caveats. Most main segments have elevator or ramp access — the Cultural Center, Macy's, Millennium Station, Block 37, and Daley Center are all accessible entrances. Some older skybridges and historic-building connections are stairs-only. The Inside Chicago "Open Your Eyes" tour explicitly notes the route involves several staircases, so the public guided tour is not fully accessible. Email Pedway@CityofChicago.org to plan a fully accessible self-guided route.

Yes, with two notes. Kids 5 and up pay $30 on the Inside Chicago tour; under 5 are free. The 2-hour duration and 1.5-mile distance is fine for kids 7+ but tough on smaller children — strollers are awkward on staircases. The hooks that work for kids: the Macy's food court (lunch reward), the Athletic Association concourse, and the underground swimming pool view. For kids under 7, the self-guided 45-minute taster route is the better call.
