The picks

How these were ranked: the day list weighs town size, county-seat walkability and drive time; the overnight list weighs estimated hotel depth. Every number repeats the table above, so nothing new to trust — just a shorter list to read.

The fuel math, in five sentences

One tank means round-trip miles under the 400-mile default with margin: we keep one-way trips at or under 200 miles so you roll home above empty. Fuel use is miles divided by 25 mpg — the thirstiest loop here (374.0 mi) works out to 15.0 gallons, about $52.36 at $3.50 a gallon. Because our miles are estimated, not routed, add a gallon of headroom. Hills, roof boxes and city crawling all shave range. If your tank runs smaller than 400 miles, drop the farthest rows first.

Common questions

How far can you get from Chicago on one tank?
About 200 one-way miles on our 400-mile-tank assumption — the farthest row in the table is Mattoon at 374.0 mi round trip.
Is Indianapolis a day trip from Chicago?
Yes — 3 h 29 each way leaves more than half the day on the ground.
What if your tank is smaller than 400 miles?
Cut the farthest rows first: anything over 170 one-way miles gets tight below a 340-mile usable tank. The gallons column lets you re-rank for your own car.
Where should you stay overnight on these trips?
Milwaukee leads our overnight picks — an estimated 28 hotels about 1 h 43 out. The Saturday button above checks dates for you.
