Leave Darlington, Maryland around 6:00 AM for the roughly 11–12-hour drive to Chicago, allowing time for fuel, meals, and traffic. Take US-40/I-70 west, then I-76/I-80 toward Indiana and I-90 into Chicago; the busiest sections are usually around Cleveland, Gary, and the Chicago approach. Keep the route flexible with live traffic updates, and plan a fuel stop every two to three hours. If you’re staying downtown, reserve hotel parking in advance—overnight garages commonly run $45–75, while street parking is scarce and heavily restricted.
After checking in, head to Millennium Park for an easy 45-minute stroll. See Cloud Gate (“The Bean”), Crown Fountain, and the skyline views toward Lake Michigan; the park is generally open until 11:00 PM, though individual attractions and seasonal installations vary. From there, walk or take a short rideshare to Lou Malnati’s Pizzeria in River North. Allow about 1½ hours for deep-dish: a pizza usually takes 30–45 minutes, so order promptly, and expect roughly $20–35 per person before drinks and tip. A reservation is useful at dinner, especially on a weekday arrival when conventions or events may fill nearby restaurants.
Finish at the Chicago Riverwalk, reached easily on foot from River North. The riverside path is especially atmospheric after dark, with illuminated bridges and architecture reflected in the water; allow about 45 minutes and stay on the main lit promenade. It is generally open until 11:00 PM, but some concessions close earlier. If you’re tired after the long drive, keep this as a short out-and-back rather than trying to cover the entire waterfront, then return to your hotel on foot or by a short rideshare.
Leave Chicago around 7:00 AM and stay on I-90 west toward Sioux Falls, allowing 8–9 hours with fuel, meal, and rest stops. The route is straightforward but long; good places to pause are the Wisconsin Dells area or La Crosse, where you can stretch and refuel before continuing across southern Minnesota. Keep snacks and water in the car, and expect rural stretches with fewer services. With a mid-afternoon arrival, park once in central Sioux Falls rather than moving the car repeatedly; downtown garages and street parking are generally easier after business hours.
Start at Falls Park, the city’s signature attraction along the Big Sioux River. Allow about an hour to follow the paved paths around the falls, mill ruins, and observation areas; it is free, open year-round, and especially pleasant in the late afternoon light. From there, walk roughly 10–15 minutes into downtown for SculptureWalk Sioux Falls, a rotating outdoor exhibition spread along the streets and public spaces. It is an easy, low-key way to see the center of town without committing to another museum, and you can wander at your own pace.
Have dinner at Crawford’s Bar & Grill, a relaxed downtown choice with American comfort food and drinks, typically about $20–35 per person. After dinner, drive or walk toward the Big Sioux River waterfront for Arc of Dreams, the illuminated steel arch spanning the river. The brief stop takes about 20 minutes and is best around sunset or after dark, when the structure photographs dramatically. Check the restaurant’s hours before setting out, since weekday closing times can vary, and keep tonight easy: tomorrow’s drive toward Badlands National Park is another early start.
Leave Sioux Falls around 7:00 AM and follow I-90 west toward Wall, keeping the tank topped up before leaving the interstate. After roughly 4½ hours of driving, stop at Wall Drug Store for coffee, snacks, and a quick browse through its quirky roadside displays and local-history exhibits. Allow about 45 minutes; most shops generally open by 8:00 AM, but check seasonal hours before setting out. From Wall, continue west briefly, then enter Badlands National Park at the Pinnacles Entrance—have a credit card ready for the park pass, and download maps in advance because cell service is unreliable.
Drive the Badlands Loop Road eastward toward Interior, allowing two to three hours for the scenic pullouts rather than treating it as a straight-through route. The formations change constantly, and overlooks such as Pinnacles Overlook and Yellow Mounds Overlook are worth lingering at; carry water, since shade and services are scarce. Continue to the Door/Window trailhead for the Door Trail, a short but rugged boardwalk-and-prairie hike taking about an hour. Stay on marked routes and wear sturdy shoes—the terrain can be uneven, and September weather can shift quickly.
Finish the park drive at Big Badlands Overlook, where the low afternoon light brings out the reds and golds in the eroded ridges. Give yourself about 30 minutes, then drive into Interior for provisions or a casual dinner at The Ranch Store Campground & Trading Post. Expect roughly $15–30 per person and about an hour for the stop; hours can be seasonal, so call ahead if arriving after 6:00 PM. Buy drinks and snacks before settling in, as Interior has very limited evening services, and refuel in Wall if you plan to explore the park again tomorrow.
