Chicago Layover Near Willis Tower: Skydeck and the LaSalle Street Canyon
Part of the full Chicago Layover Guide: What to Do Before a Late Flight Out of O'Hare

If Willis Tower is the anchor for your layover rather than Millennium Park, you’re already positioned for a South Loop itinerary that looks nothing like the museum-and-park walk most Chicago guides default to.
Can’t-miss
Store your bag nearby, then head up to the Willis Tower Skydeck. The main draw is The Ledge: glass balconies that extend several feet out from the building, giving a straight-down view more than 1,300 feet to the street. It’s the single most efficient way to see the whole city at once, if you don’t mind the line.
The Skydeck’s ticket line moves slowly at peak times, and LaSalle Street’s sidewalks narrow between tall buildings where wind funnels through; neither is improved by hauling a suitcase along for it.
If you have more time
Back at street level, walk north up LaSalle Street: a canyon of early-1900s bank buildings that ends at the Chicago Board of Trade Building, whose stepped Art Deco tower is one of the most recognizable silhouettes in the Loop. It’s a free, flat walk that pairs well with the Skydeck without requiring a second ticket or a long detour.

Getting back to O’Hare
The nearest CTA Blue Line entrances are a short walk from Willis Tower; board there for the direct, roughly 45-minute ride to O’Hare. Leave at least 90 minutes total before your flight for the trip, check-in, and security.
Frequently asked questions
How long does the Skydeck actually take?
Budget at least an hour once you count the ticket line, security screening, and the elevator ride, longer on busy afternoons. Buying tickets online ahead of time skips one of those lines.
Is LaSalle Street worth seeing if I skip the Skydeck?
Yes, it costs nothing to walk it, and the canyon of early-20th-century bank buildings capped by the Chicago Board of Trade Building's Art Deco tower is one of the most distinct streetscapes downtown, independent of anything at Willis Tower itself.
Where should I store my bag for this itinerary?
A luggage storage point in the South Loop, close to Willis Tower, works better than one further north near Millennium Park; it keeps both the Skydeck and LaSalle Street a short walk away.
Is this a good itinerary for a shorter layover?
If your window is under 3 hours, treat the Skydeck as an either/or with LaSalle Street rather than both; the ticket line alone can eat the time you'd need for a relaxed walk afterward.
