Great River Road Road Trip Guide
Start: Lake Itasca State Park, Minnesota (Mississippi headwaters). End: Venice, Louisiana / the Gulf of Mexico below New Orleans (end of Louisiana Highway 23, the southernmost point reachable by road). · About 3,000 miles following the Mississippi River through 10 states (Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, Louisiana). The route is a network of state and US highways marked by the green pilot's-wheel/steamboat sign, not a single continuous road.
Route at a Glance
Distance
About 3,000 miles following the Mississippi River through 10 states (Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, Louisiana). The route is a network of state and US highways marked by the green pilot's-wheel/steamboat sign, not a single continuous road.
Drive time
Non-stop driving is roughly 50-55 hours. A realistic full traverse takes 10-14 days; many travelers drive only one state segment (each is a comfortable 1-3 day trip).
Route
Start: Lake Itasca State Park, Minnesota (Mississippi headwaters). End: Venice, Louisiana / the Gulf of Mexico below New Orleans (end of Louisiana Highway 23, the southernmost point reachable by road).
Which way to drive
Drive north to south, from Lake Itasca (the Mississippi headwaters) to the Gulf of Mexico. This follows the river's flow downstream and builds the trip narrative from a stream you can step across to the delta.
About the Great River Road Drive
The Great River Road follows the Mississippi River for approximately 3,000 miles through 10 states from Lake Itasca in northern Minnesota (where you can walk across the Mississippi's 18-foot-wide headwaters) to the river's mouth at Venice, Louisiana. The road is not a single highway but a network of marked federal, state, and county roads tracing both banks of the river. The upper river section through Minnesota and Wisconsin features dramatic bluffs — the stretch through the Driftless Area between La Crosse, Wisconsin, and Dubuque, Iowa, has 600-foot limestone bluffs and bald eagle concentrations. In the middle section, Hannibal, Missouri (milepost approximate 780), is Mark Twain's boyhood home. The lower river passes through the Mississippi Delta — Clarksdale, Mississippi, is the crossroads of the blues, home to the Delta Blues Museum and legendary juke joints. Below New Orleans, the river road passes antebellum plantation houses before reaching the marshes at the Gulf.

Don't-Miss Sights Along Great River Road
- •Lake Itasca headwaters — the source of the Mississippi River in northern Minnesota, where you can walk across stepping stones over the 18-foot-wide stream
- •Great River Bluffs State Park (Minnesota) — 600-foot limestone bluffs overlooking the Mississippi floodplain between La Crosse and Winona with bald eagle viewing in winter
- •Natchez, Mississippi — a city of over 1,000 pre-Civil War structures perched on bluffs above the river, with the Natchez Under-the-Hill district on the waterfront
- •Clarksdale, Mississippi — the epicenter of Delta blues music with the Delta Blues Museum, Ground Zero Blues Club (co-owned by Morgan Freeman), and the legendary crossroads of Highways 61 and 49
Best Viewpoints
- •Grandad Bluff, La Crosse, WI (~590 ft above the river, panorama into MN and IA)
- •Effigy Mounds National Monument overlooks, Marquette, IA (Fire Point bluff over the river valley)
- •Pikes Peak State Park, McGregor, IA (~500 ft bluff opposite the Wisconsin River confluence)
- •Great River Bluffs State Park, MN (bluff-top overlooks near Winona)
- •Tower Rock area, southern Illinois & Missouri (river narrows and rock formations)
Worthwhile Detours off Great River Road
- •Effigy Mounds National Monument (Iowa) — over 200 prehistoric mounds, including 31 shaped as bears and birds, built 750-1,400 years ago on bluffs 300 feet above the river
- •Pilottown, Louisiana — an almost-abandoned river pilot community near the Mississippi's mouth, accessible only by boat, where river pilots board ships entering from the Gulf
Fuel, Food & Services
Towns are frequent through the upper Midwest, but in northern Minnesota near Itasca and in rural stretches of Arkansas, Mississippi, and the Louisiana river-road plantation country, plan fuel stops 50-70 miles apart. South of New Orleans on LA-23 toward Venice, services thin out sharply—fill up in Belle Chasse before continuing. Memphis, St. Louis, Minneapolis-St. Paul, and Baton Rouge are reliable full-service hubs.
Road Conditions
Mostly two-lane state and US highways at moderate speeds; no major mountain passes, tunnels, or hairpins. Expect bluff-climb grades and winding river-hugging sections in WI, IA, and MN. Numerous river crossings via bridges; some ferries operate seasonally. Cell coverage is good near towns but spotty in rural delta stretches and northern Minnesota. Watch for agricultural traffic and flood-related detours in low-lying Louisiana/Mississippi sections during high-water spring months.
Best Season to Drive
Late September to mid-October for fall color along the northern bluffs (MN, WI, IA). Summer (June-August) is fully open everywhere but hot and humid in the South. Lake Itasca park facilities and some northern overlooks have limited winter access; spring (April-May) can bring Mississippi flooding and road closures in the lower valley.
RVs & Trailers
Suitable for RVs and trailers—roads are paved highways with no posted vehicle-length or weight restrictions on the main route. Some bluff-top state park overlook spurs (e.g., narrow loop roads at Pikes Peak or Itasca's Wilderness Drive) are tight for large rigs; check individual park rules. Most campgrounds along the route accommodate RVs.
