Book these before you go

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 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.

Do you need a car for this itinerary?

No. The Blue Line covers the airport, the Hiawatha covers Milwaukee, and both the Route 66 sign and Union Station’s Great Hall sit within walking distance of the Loop. Check current CTA fares on transitchicago.com before day one, since the last increase landed in February 2026.

Is 2 days enough for a Chicago gateway trip?

Enough for the cheapest one, yes. Two days covers the free orientation and the single best-value interstate day trip on this list, Milwaukee for as little as $19 each way. It skips Indiana Dunes National Park entirely, since that’s a separate train from a separate downtown station. Nest into the 3-day version to add it, or see the full gateway guide for the cost breakdown on every option.

Book the Hiawatha the moment your dates are set; it’s the one piece of this trip that actually sells out on summer weekends.
