Marietta to Iowa City Road Trip: Best Stops and Hidden Gems

The drive from Marietta, Ohio, where the Muskingum and Ohio Rivers converge, to Iowa City, Iowa, home to the University of Iowa, covers roughly 540 miles and takes about 8.5 hours without stops. This route follows I-77 north to I-70 west, then I-74 west and I-80 west, crossing five states. A little-known fact: Marietta was the first permanent settlement in the Northwest Territory, founded in 1788, while Iowa City served as the second capital of Iowa Territory from 1841 to 1857.

Along the way, travelers traverse the Appalachian foothills, the flat farmlands of Indiana and Illinois, and the rolling hills of eastern Iowa. The transition from forested ridges to vast cornfields and soybean fields marks a quintessential American journey. This guide helps you find how to find the best stops and hidden gems between cities.

Here is a quick overview of the route:

The interstates are generally well-maintained with good signage. In winter, snow and ice are common from December through March; check weather forecasts and carry emergency supplies. Summer brings thunderstorms, especially in Illinois and Iowa.

For families, kid-friendly stops include The Children's Museum of Indianapolis (world's largest) just off I-70 in downtown Indy, and the Henry Doorly Zoo in Omaha (if willing to detour). For rest, the Indiana Dunes National Park (north of I-80/94) is a 2-hour detour but offers beaches and dunes on Lake Michigan.

To manage fatigue, plan stops every 2 hours. Good rest areas include the Valley View Rest Area in Ohio (mile 121 on I-70) with a scenic overlook, and the Amana Rest Area in Iowa (mile 225 on I-80) with a welcome center. Pet-friendly stops: many rest areas have pet relief areas; the West Liberty service plaza has a fenced dog run. Most motel chains along the route accept pets with a fee.

The primary route uses I-77 north from Marietta to I-70 west near Columbus, then transitions to I-74 west at Indianapolis, and finally I-80 west to Iowa City. Alternative routing via US-35 and US-33 offers a more scenic but slower option through southern Ohio and Indiana. Fuel costs vary: Ohio averages $3.30/gallon, Indiana $3.40, Illinois $3.60, and Iowa $3.20 (as of 2025). Budget roughly $80-$100 for fuel for a standard sedan.

Tolls are minimal—only a small stretch on I-80 in Illinois near the Mississippi River ($1.50 for passenger cars). Rest stops are well-spaced every 30-40 miles on interstates. Notable service plazas include:

• West Liberty, OH (mile marker 66 on I-70)
• Richmond, IN (mile marker 156 on I-70)
• Effingham, IL (mile marker 160 on I-70/57)

From Marietta, the route climbs into the Appalachian foothills—rolling wooded hills with glimpses of the Muskingum River. After Columbus, the land flattens into the heart of the Corn Belt. In Indiana, vast agricultural fields extend to the horizon, punctuated by grain elevators and small farm towns. Notable natural attractions include Hueston Woods State Park in Ohio (just off I-70 near Oxford) and Turkey Run State Park in Indiana (near Rockville). Both offer hiking trails and scenic gorges.

Local commerce along the route includes Amish markets in eastern Indiana (e.g., in Geneva or Berne) and roadside farm stands selling fresh produce and homemade pies in Illinois. In Iowa, the Amana Colonies (a group of seven historic villages) offer wineries, bakeries, and handcrafted goods. They are a short detour off I-80 at Exit 225.
