Whether you're seeking the best stops from Ann Arbor to Solomons or wondering how long to drive between these points, this guide covers everything.

• Total distance: ~550 miles via I-75 S, I-70 E, and US-301 S
• Driving time: 8.5–9.5 hours without stops
• Optimal season: Late spring (May) or early fall (September) for mild weather

The primary route uses I-75 South from Ann Arbor to Dayton, then I-70 East across Ohio and into Maryland. From Hagerstown, take US-301 South toward the Chesapeake Bay, then MD-4 to Solomons. The roads are well-maintained interstates and highways, with only the final 30 miles on two-lane roads through Calvert County. Toll costs are minimal: only the I-70 Eisenhower Tunnel ($0) and the US-301 Nice Bridge (about $2 for cars). Gas stations are plentiful roughly every 20–30 miles along the interstates, but become sparse on the final leg near the Chesapeake.

• Best fuel stops: Cambridge, OH (exit 176 on I-70); Washington, PA (exit 15 on I-70); Hagerstown, MD (exit 32 on I-70).
• EV charging: Tesla Superchargers at Columbus, OH; Wheeling, WV; Hagerstown, MD.
• Road quality: Excellent on interstates; watch for potholes on US-301 in Maryland.

Safety on this route is generally high, but fatigue is a real risk due to the monotony of long interstate stretches. Plan to stop every 2 hours or 150 miles. The best rest areas are the I-70 Ohio Rest Area at mile 131 (eastbound) and the Maryland House on I-95 (though off-route, a good backup). For families, the Columbus Zoo and Aquarium (just off I-71) is a major attraction, and the National Museum of the US Air Force in Dayton is another excellent stop. Pet-friendly parks include the dog run at the Wheeling Heritage Trail in West Virginia and the Calvert Cliffs State Park (dogs on leash).

• Recommended rest stops: Rest area near Zanesville, OH (mile 161 on I-70); Rest area near Frederick, MD (mile 42 on I-70).
• Family attractions: COSI museum in Columbus; The Wilds safari park in Cumberland, OH; Solomons Island boardwalk.
• Pet stops: PetSmart in Hagerstown (for supplies); Annmarie Garden in Solomons (leashed pets allowed).

This route showcases the transition from the Great Lakes forests to the Appalachian Mountains and finally the Tidewater region. In Ohio, you'll pass through the rolling hills of the Appalachian foothills, with the Muskingum River Valley near Cambridge. The deepest gorge on the route is the Youghiogheny River Gorge in southwestern Pennsylvania, visible from I-70. In Maryland, the landscape flattens into the Chesapeake Bay watershed, with marshes and pine forests.

• Must-see natural attractions: Hocking Hills State Park (detour 30 min south of Columbus); Swallow Falls State Park (western Maryland); Calvert Cliffs State Park (fossil hunting on the bay).
• Local commerce: Visit the historic town of Cambridge, OH, for antique shops; stop at the Washington County Farm Museum in Hagerstown; browse the Solomons Farmers Market (Sat mornings).
