Great River Road Upper Mississippi Trail
Hidden river roads through Iowa's backwater wilderness
The Great River Road’s backcountry spurs drop off the main scenic highway into forgotten timber and river bottoms that most tourists never see. Gravel county roads like 52nd Avenue and Blackhawk Creek Road wind through dense hardwood forests to secluded boat launches and primitive campsites where the Mississippi’s backwaters create a maze of sloughs and islands. The real adventure starts at Credit Island Park, where unmarked two-tracks branch into Davenport’s industrial river bottom—old railroad grades and levee roads that dead-end at towboat channels.
Easy driving for any vehicle with decent ground clearance, though spring floods can wash out low sections without warning. Best explored April through October when water levels stabilize and mosquitoes aren’t biblical. No permits needed, but respect private property—some timber companies still use these roads for logging access. What you get is Iowa’s wildest river country and the chance to camp on sandbars that shift with every flood.

Frequently asked questions
Can a stock SUV handle this trail?
Yes, high-clearance 2WD is sufficient for the gravel surface. Any decent crossover or pickup can run this without issues.
Is the trail accessible in spring?
Best to wait until April when flood waters recede and gravel roads dry out. Spring flooding can make sections impassable.
Do I need permits to camp along the trail?
No permits required for dispersed camping on public land sections managed by Scott County Parks. Follow Leave No Trace principles.
What's the most challenging part of the trail?
The water crossings through backwater sloughs - they're shallow but can be muddy. Nothing technical, just take it slow.
How's cell coverage for navigation?
Decent cell service throughout most of the route since you're close to the Quad Cities area. Download offline maps as backup for the remote slough areas.
