Book these before you go
- Book a Milwaukee brewery or architecture tour on GetYourGuide , the day two centerpiece; summer weekend slots sell out.
- Compare Loop and River North hotel rates on Booking.com before locking in a neighborhood for the trip.
- Search Milwaukee hotel rates on Booking.com if you’d rather split the trip with an overnight than return same-day.
| Day | Focus | Distance/time from Chicago | Cost |
|---|---|---|---|
| Day 1 | Chicago gateway orientation: Union Station, the Route 66 Begin sign | In Chicago | $15-30 |
| Day 2 | Milwaukee day trip via Amtrak Hiawatha | ~90 min train | $45-80 |
| Day 3 | Indiana Dunes National Park via the South Shore Line | ~1h train | $20-35 |
Day 1: Chicago basecamp, gateway orientation
Morning: land at O’Hare and ride the Blue Line downtown ($2.75 tapped on a Ventra card or a contactless bank card, about 45 minutes, the only Chicago airport line that runs 24/7), or Midway’s Orange Line (25-30 minutes, but mind its overnight service gap if you’re landing very early or late). Check into a Loop or River North hotel and pick up a Ventra card ($5, refunded as transit credit if registered online within 90 days) if you’re not just tapping a bank card.
Midday: walk to Union Station’s Great Hall (225 S Canal St), the free 1925 Beaux-Arts landmark that makes Chicago a national rail hub in the first place. Check the departure board for the six long-haul lines out of here, the California Zephyr, Empire Builder, Lake Shore Limited, Capitol Limited, Texas Eagle, and City of New Orleans, even on a day you’re not riding one.
Afternoon: walk or ride the Red Line to the Route 66 “Begin” sign at Adams Street and Michigan Avenue, standing since roughly 1955, then over to Navy Pier for the new 2026 centennial ceremonial starting point, dedicated March 25, 2026. Both are free photo stops, no ticket required for either.
Evening: a Chicago hot dog ($4-8, no ketchup) or an Italian beef sandwich ($8-13) for dinner.
Day 1 running total: roughly $15-30 per person, transit and food only, before any hotel cost.
Day 2: Milwaukee on the Hiawatha
Morning: catch a morning Amtrak Hiawatha from Union Station (seven weekday and Saturday round trips, six on Sunday), the 90-minute run to downtown Milwaukee, advance fares $19-37 one-way depending on demand. Book a summer Saturday run a few days ahead; it does sell out.
Midday: walk the Milwaukee lakefront, then the Milwaukee Public Market for lunch, a food hall where you pay per vendor rather than for admission.
Afternoon: the Lakefront Brewery tour ($13 weekday, $16 weekend, two pours and a souvenir glass included) is one of the better-value brewery tours in the Midwest, or catch the Milwaukee Art Museum free on a first Thursday if the dates line up.
Evening: an evening Hiawatha back to Chicago; check the timetable before committing to a late Milwaukee dinner, since the last train back runs earlier than a typical Chicago night out.
Day 2 running total: roughly $45-80 per person, train fare, one paid activity, and food.
Day 3: Indiana Dunes National Park, free at the end of a cheap train
Morning: the South Shore Line runs direct from Millennium Station through about 20 stops, including Hammond, Gary, and East Chicago, to Dunes Park, roughly an hour, one-way fares in the $9-10 range. Check the current schedule at mysouthshoreline.com before you go; a June 24, 2026 freight derailment near East Chicago cut weekday service for several weeks, with full Monday-Friday service only resuming July 17, 2026.
Midday: entry and parking are both free at the national park itself; pick a lakefront beach or a dune trail depending on how much walking the day calls for.
Afternoon: pack a lunch or eat near Dunes Park station; options thin out fast once you’re past the platform.
Evening: the same South Shore Line back to Millennium Station.
Day 3 running total: roughly $20-35 per person, train fare and food, the park itself free.
Do you need a car for this itinerary?
No. The Blue Line covers the airport, the Hiawatha covers Milwaukee, and the South Shore Line covers Indiana Dunes from a separate downtown station, Millennium Station rather than Union Station. Check current CTA fares on transitchicago.com before day one, since the last increase landed in February 2026.
Is Indiana Dunes worth a full day next to Milwaukee?
Yes, and for less money. The Dunes trip runs shorter and cheaper than Milwaukee, about an hour each way for roughly $9-10, with a national park that charges nothing to enter. The tradeoff is schedule risk: 2026’s derailment-driven service cuts are a reminder to check mysouthshoreline.com before building a day around a specific departure time. Nest into the 5-day version to add Racine next, or see the full gateway guide for the cost breakdown on every option.
Check the South Shore Line’s current schedule the night before day three; it’s the one leg on this trip with real 2026 disruption history.
