This road trip takes you through four states, with underground caves, forest hikes, historic sites, scenic rivers, and some seriously good food waiting along the way.
Instead of racing south on the interstate, this itinerary turns the drive into part of the fun.
We’ve included stops where you can hike beneath towering trees, explore deep underground, walk across huge bridges, and learn a few surprising stories from American history.
Keep reading for the best stops, things to do, driving distances, and tips for turning the journey south into a road trip you’ll be talking about long after you get home.
1. Grand Rapids, Michigan
Grand Rapids sits along the Grand River in western Michigan, making it a great starting point for your road trip south toward Tennessee.
Known as “Beer City USA,” Grand Rapids has more than 40 breweries, including Founders Brewing Co., plus the Grand Rapids Downtown Market packed with local food and treats.
Don’t miss Frederik Meijer Gardens & Sculpture Park, a 158-acre attraction featuring huge outdoor sculptures, peaceful gardens, and the five-story Lena Meijer Tropical Conservatory.
You can also explore the Gerald R. Ford Presidential Museum or stroll the Rosa Parks Circle downtown.
2. South Bend, Indiana
Cross into Indiana and make South Bend your next stop, located along the St. Joseph River, about 1 hour and 45 minutes from Grand Rapids and near the Michigan state line.
The big name here is the University of Notre Dame, where you can explore the campus, which spans more than 1,200 acres.
Make sure to stop to see the famous Golden Dome, visit the Basilica of the Sacred Heart, and snap a photo beneath the 134-foot-tall “Touchdown Jesus” mural.
Car fans should head to the Studebaker National Museum, which displays vehicles from the South Bend company that built wagons and cars here for more than a century.
Before continuing south, walk along the East Race Waterway, a 2,000-foot artificial whitewater course where you can even tackle Class II rapids during summer rafting sessions.
Please note that East Race Waterway is closed for the 2026 season due to scheduled construction. Reopening is expected for the 2027 season. Be sure to check online for updates before visiting.
3. Indianapolis, Indiana
About a 2.5-hour drive from South Bend, you’ll reach Indianapolis, Indiana’s capital and a city packed with racing legends, massive monuments, and seriously fun museums.
Start at the Indianapolis Motor Speedway, home of the Indianapolis 500 since 1911, where the famous 2.5-mile oval can hold more than 250,000 spectators.
Downtown, climb 330 steps inside the Soldiers and Sailors Monument for skyline views, then follow part of the 8-mile Indianapolis Cultural Trail connecting neighborhoods, public art, restaurants, and parks.
If you have extra time, explore the Children’s Museum of Indianapolis, the world’s largest children’s museum, or visit White River State Park, a 250-acre downtown green space housing the Indianapolis Zoo and several major attractions.
4. Brown County State Park, Indiana
Trade Indianapolis traffic for forest roads by driving about 1 hour to Brown County State Park, Indiana’s largest state park at nearly 16,000 acres.
Known for its steep hills, ravines, and huge fall color displays, the park has nearly 20 miles of roads with overlooks including Hesitation Point, where you can gaze across miles of wooded ridges.
For a closer look, hike Trail 5, a moderate 1.2-mile loop that passes Ogle Lake, or tackle the 3.5-mile Trail 8 through some of the park’s hilliest terrain.
You can also climb the 90-foot Fire Tower, ride more than 30 miles of mountain biking trails, or spot white-tailed deer before continuing your road trip south.
5. Louisville, Kentucky
After the wooded hills of Brown County, drive roughly 1 hour and 25 minutes and cross the Ohio River into Louisville, Kentucky, a city famous for horse racing, bourbon, baseball bats, and Muhammad Ali.
Start at Churchill Downs, where the Kentucky Derby has been held since 1875 on a 1-mile dirt track, then check out the Kentucky Derby Museum next door.
Baseball fans can visit the Louisville Slugger Museum & Factory on Museum Row, where a 120-foot-tall baseball bat leans outside and factory tours show how the famous wooden bats are made.
Save time for the Muhammad Ali Center, stroll part of the 85-acre Waterfront Park, or cross the Ohio River on the 2,562-foot Big Four Bridge before heading farther south.
6. Mammoth Cave National Park, Kentucky
Leave Louisville behind and drive about 1.5 hours to Mammoth Cave National Park, where Kentucky’s rolling countryside hides the longest known cave system on Earth.
More than 420 miles of Mammoth Cave have been explored and mapped, with ranger-led tours taking you past giant chambers, narrow passages, historic saltpeter mining sites, and unusual rock formations deep underground.
Choose the popular 2-hour Historic Tour for roughly 2 miles of underground exploring, including the tight passage called Fat Man’s Misery, or stay above ground on the Cedar Sink Trail.
The 52,830-acre park also protects forests and the Green River, so you can hike, paddle, camp, and spot wildlife.
7. Fall Creek Falls State Park, Tennessee
Continue to Fall Creek Falls State Park, about a 3-hour drive from Mammoth Cave, where more than 29,800 acres on the Cumberland Plateau are filled with waterfalls, gorges, forests, and hiking trails.
The star is Fall Creek Falls, a 256-foot waterfall that plunges into a rocky gorge and ranks among the tallest waterfalls in the eastern United States.
Take the 0.35-mile Base of Fall Creek Falls Trail for a steep trip to the bottom, or follow the 1.2-mile Gorge Overlook Trail for views of Fall Creek Falls, Cane Creek Falls, and Cane Creek Gorge.
You can also cross the suspension bridge near the Nature Center, paddle Fall Creek Falls Lake, play the park’s 18-hole golf course, or stay overnight at the Lodge at Fall Creek Falls.
8. Chattanooga, Tennessee
From the waterfalls of Fall Creek Falls, drive about 1 hour to Chattanooga, where the Tennessee River curves through downtown beneath the steep slopes of Lookout Mountain.
Head underground at Ruby Falls to see a 145-foot waterfall inside Lookout Mountain, then ride the Lookout Mountain Incline Railway.
Back downtown, the Tennessee Aquarium fills two buildings with river otters, sharks, alligators, penguins, and thousands of other animals, while the nearby Walnut Street Bridge stretches 2,376 feet across the Tennessee River.
For one last outdoor adventure, walk part of the Tennessee Riverwalk or visit nearby Point Park, a 10-acre Civil War battlefield with sweeping views across Chattanooga and the river.
