Book these before you go

Day Focus Distance / travel time from Chicago
Day 1 Arrival, Millennium Park, Cloud Gate, the Riverwalk, architecture cruise In Chicago
Day 2 Skydeck or 360 CHICAGO, Navy Pier, the Art Institute In Chicago
Day 3 Milwaukee day trip ~90 min each way, Amtrak Hiawatha

Day 1: Arrival and the Loop

  • Land at O’Hare and ride the Blue Line downtown, about 45 minutes and the only one of Chicago’s two airport rail lines that runs 24 hours a day; landing at Midway instead, the Orange Line is faster at 25-30 minutes but has a real overnight service gap, so don’t count on it for a very early or very late arrival
  • Check into a hotel in the Loop or River North, both put you inside a short walk of Union Station and the Magnificent Mile
  • Walk Millennium Park, free, and photograph Cloud Gate (“the Bean”), then follow the Riverwalk south toward the Loop
  • Book the Chicago Architecture Center’s river cruise for late afternoon if you haven’t already, popular slots sell out May through November
  • Dinner in the Loop or River North; save a full deep-dish meal for a group, it’s not really a solo-portion dish

Day 2: Skyline and the lakefront

  • Morning at the Willis Tower Skydeck (from $32 adult, access to The Ledge glass balconies included) or 360 CHICAGO (from $30 weekday, $35 weekend); pick one, not both, they show the same skyline from opposite ends of it
  • CTA or walk to Navy Pier, free to enter; individual rides, boat tours, and the new-for-2026 Summer Skate lakefront rink are ticketed separately
  • Afternoon at the Art Institute of Chicago ($32 adult, $26 senior/student/teen), home to American Gothic and a genuinely deep Impressionist collection
  • Evening back in the Loop or River North, pack light for an early train out tomorrow

Day 3: Milwaukee, the easiest interstate day trip

  • Catch an early Amtrak Hiawatha from Union Station, about 90 minutes direct, 7 weekday and Saturday round trips a day (6 on Sunday), fares $19-37 one-way depending on demand, check current times on amtrak.com
  • Spend the day in Milwaukee’s Historic Third Ward or along the lakefront; a short brewery tour fits comfortably between trains
  • Full event calendars and neighborhood detail sit at visitmilwaukee.org
  • Catch an evening train back to Chicago; book the return leg the same day you book the outbound one, since fares climb as departure gets closer

Is Milwaukee worth a day trip from Chicago? Yes, and it’s the single easiest interstate hop on this list. Ninety minutes each way by train beats any drive-and-park option, fares stay under $40 even at peak demand, and Milwaukee’s lakefront and Third Ward genuinely stand on their own rather than reading as a smaller Chicago.

Do Hiawatha tickets need to be booked in advance? Not strictly, walk-up tickets exist, but fares rise toward the $37 ceiling as a specific departure fills up. Booking a few days ahead through amtrak.com keeps a round trip closer to the $19-25 end of the range, and it locks in a seat on the busier Friday and Sunday evening trains.

One concrete tip: build Day 3 around the earliest reasonable Hiawatha departure. Milwaukee’s Third Ward, lakefront, and a brewery tour genuinely fill a full day, and an early train buys back the couple of hours a late start costs you on the far end.
