A Long Weekend in Gateway: The Offbeat Plan
Three days adds a second state line to the two-day version: the same Chicago warm-up and Milwaukee day trip, plus a national park most visitors don’t know borders Illinois. Want the condensed weekend instead? Start at the 2-day version ; need the whole roster? The 7-day version adds Route 66, Union Station, and O’Hare.

Day 1: Chicago, the crossroads before you leave it
Start downtown, since tomorrow’s train leaves early. Walk the free Riverwalk to Millennium Park for Cloud Gate, the Bean, then head back to the Loop; a CTA 1-Day pass is $6 if today involves more than two rail trips. The deep city sights get one day here; see the Chicago hidden gems guide for the rest. Dinner in the Loop or River North, then an early night.
Day 2: Milwaukee, the easiest state line you’ll cross
Catch one of Amtrak’s Hiawatha trains from Union Station; the roughly 86-mile ride to Milwaukee takes about 90 minutes, one-way fares $19 to $37. Walk the Milwaukee Riverwalk to the Bronze Fonz, a life-size statue of Henry Winkler’s “Happy Days” character installed near Wells Street in 2008, then spend the afternoon at the Harley-Davidson Museum, general admission in the low-to-mid $20s and cheaper booked online ahead. Catch an evening Hiawatha back.
Do you need a car to do Milwaukee as a day trip?
No. The Hiawatha runs directly from Union Station to downtown Milwaukee’s Intermodal Station, and the Riverwalk, the Bronze Fonz, and the Harley-Davidson Museum all sit within walking distance or a short rideshare of that stop. A car adds parking costs without saving real time over the 90-minute train.
Day 3: Indiana Dunes, the national park next to a steel mill
Board the South Shore Line at Millennium Station for the roughly 46-mile, 66-minute ride to Dunes Park, one-way fares about $9 to $10. As of today the line is back on its full weekday schedule after a June 24 freight derailment forced a reduced timetable for three weeks; check mysouthshoreline.com before you leave in case that changes again. Entry to Indiana Dunes National Park is free. West Beach’s trails climb well over 100 feet with US Steel’s Gary Works visible across the water, a contrast no other national park offers. Pack water; the sand offers zero shade in summer.
Is one day enough for Indiana Dunes?
Yes, for a first visit. The West Beach loop fills 3 to 4 hours including the South Shore Line ride each way, which comfortably fits a same-day round trip from Chicago. A longer stay only matters if you want Mount Baldy or Cowles Bog too, both covered in the 7-day version .
Where to stay: a Loop or River North hotel for all three nights, since both Milwaukee and Indiana Dunes are same-day round trips.
