There's something about a road trip that a flight just can't replicate. You see the country change mile by mile instead of disappearing beneath the clouds, and half the best moments happen at the places you weren't even planning to stop. Road trip routes across the US offer an enormous range of scenery, from coastal cliffs to red rock canyons to quiet mountain towns, and picking the right one can make or break the whole trip.
If you're planning a drive this year, these are some of the most rewarding routes the country has to offer, along with what makes each one worth the miles.
Pacific Coast Highway, California
Few drives in the world are as consistently ranked among the best as the Pacific Coast Highway, also known as Highway 1, running along the California coastline. The full route stretches roughly from San Francisco down to San Diego, though most travelers focus on the stretch between San Francisco and Los Angeles, which passes through some of the most dramatic coastal scenery in the country.
Big Sur is the undeniable highlight, with cliffside views, redwood forests, and the iconic Bixby Bridge offering some of the most photographed scenery on the entire West Coast. Further south, Hearst Castle offers a detour into old California opulence, while towns like Cambria and Carmel-by-the-Sea provide charming stops with excellent food and small-town character.
This route is best driven slowly. The road itself is winding and narrow in places, and rushing through misses the point entirely. Plan for frequent stops at overlooks, and budget more time than you think you'll need, especially through the Big Sur stretch.
Route 66, Illinois to California
No list of American road trip routes would be complete without Route 66, the original cross-country highway that's become a symbol of classic American road culture. Stretching from Chicago to Santa Monica, the historic route passes through eight states and offers a nostalgic look at mid-century roadside America, complete with vintage diners, quirky roadside attractions, and small towns that built their identity around the highway.
Highlights along the route include the Cadillac Ranch outside Amarillo, Texas, the neon-lit motels of Tucumcari, New Mexico, and the Petrified Forest National Park in Arizona. Much of the original route has been replaced by interstate highways, so navigating requires some planning, but dedicated Route 66 maps and guides make it manageable for travelers who want the full nostalgic experience.
This route works especially well for travelers interested in Americana and roadside history rather than dramatic natural scenery alone, though there's plenty of striking desert landscape in the western stretches as well.
Blue Ridge Parkway, Virginia to North Carolina
For travelers drawn to mountains rather than coastline, the Blue Ridge Parkway offers one of the most scenic and relaxed drives in the country. Stretching 469 miles through the Appalachian Mountains, connecting Shenandoah National Park in Virginia to Great Smoky Mountains National Park in North Carolina, the parkway is specifically designed for scenic driving, with a lower speed limit and frequent overlooks built into the route.
Fall is an especially popular time to drive the Blue Ridge Parkway, when the mountain foliage turns into a sweeping display of color, though the route is beautiful throughout spring and summer as well, with wildflowers and lush green mountain views. The drive passes numerous hiking trailheads, waterfalls, and small mountain towns worth stopping in along the way.
Because the parkway has no commercial traffic and a consistently low speed limit, it tends to be one of the more relaxed and low-stress routes on this list, making it a strong option for travelers who want scenic driving without heavy traffic or complicated navigation.
The Great River Road, Along the Mississippi River
For a road trip that captures a different side of the country, the Great River Road follows the Mississippi River for roughly 3,000 miles, from Minnesota down to Louisiana. This route offers a genuinely unique cross-section of American culture, passing through the Midwest, the Deep South, and everything in between.
Highlights include the river bluffs of Minnesota and Wisconsin, the historic river towns of Iowa and Illinois, the blues heritage of the Mississippi Delta, and the vibrant culture of New Orleans at the route's southern end. Because the full route is so long, most travelers choose to drive a specific section rather than the entire route in one trip.
This drive is particularly rewarding for travelers interested in American history, music, and food culture, since the route passes through regions with deeply distinct culinary and musical traditions that shift noticeably as you move south.
Going-to-the-Sun Road, Montana
For travelers chasing dramatic mountain scenery, Going-to-the-Sun Road through Glacier National Park in Montana is one of the most spectacular, if shorter, drives in the country. The 50-mile route crosses the Continental Divide and offers sweeping views of glacially carved peaks, alpine lakes, and, weather permitting, actual glaciers.
This road is seasonal, typically fully open only from early summer through fall due to heavy snowfall, so timing matters significantly for this particular route. It's also narrow and winding in sections, with limited vehicle size restrictions in some areas, so checking current park guidelines before planning your trip is essential.
Because the route itself is relatively short, it works particularly well as part of a larger Montana or Pacific Northwest road trip rather than a standalone destination drive.
Overseas Highway, Florida Keys
For a completely different kind of scenery, the Overseas Highway connecting Key Largo to Key West offers a drive unlike anything else in the country, crossing more than forty bridges over open ocean water as it hops between islands. The Seven Mile Bridge in particular has become one of the most iconic stretches of road in the country, offering uninterrupted ocean views in both directions.
This route is relatively short at around 113 miles, making it an easy addition to a broader Florida trip. Along the way, travelers can stop for snorkeling, fishing, and fresh seafood, with Key West at the route's end offering a distinctly laid-back, tropical atmosphere as a rewarding final stop.
Unlike the mountain and coastal routes further north, this drive works well nearly year-round, though hurricane season, roughly June through November, is worth factoring into travel plans given Florida's exposure to tropical storms.
Utah's Scenic Byway 12
Utah's Scenic Byway 12 has earned a reputation among road trip enthusiasts as one of the most visually stunning and underrated drives in the country. The route winds through south-central Utah, connecting Bryce Canyon National Park to Capitol Reef National Park, passing through dramatic slot canyons, red rock formations, and high desert plateaus along the way.
The section through Grand Staircase-Escalante National Monument is a particular highlight, with otherworldly rock formations that feel distinctly different from more well-known national parks nearby. Because this route passes through more remote sections of Utah, it's worth planning fuel stops carefully, since services can be spread out along parts of the drive.
This route pairs especially well with a broader Utah national parks road trip, since it connects naturally with other major parks in the region for travelers wanting to see multiple iconic Utah landscapes in one trip.
Planning Tips for Any Route
Regardless of which road trip routes you choose, a few planning basics tend to make the difference between a smooth trip and a stressful one. Building in more time than feels strictly necessary is one of the most valuable habits for road trip planning, since the best moments often come from unplanned stops rather than sticking rigidly to a schedule.
Checking road conditions and seasonal closures ahead of time matters significantly for mountain and high-elevation routes in particular, since weather can affect accessibility more than travelers from other regions might expect. Downloading offline maps is worth doing for routes that pass through remote areas with limited cell service, which applies to several of the routes on this list.
Booking accommodations in advance during peak travel seasons is worth considering for popular routes, since small towns along scenic byways often have limited lodging options that fill up quickly during high season.
The Bottom Line
The best road trip routes in the US genuinely span an enormous range of landscapes and experiences, from rugged coastline to mountain passes to quiet river towns. Whether you're drawn to dramatic natural scenery, roadside Americana, or a mix of both, there's a route on this list suited to almost any kind of traveler.
The National Park Service maintains detailed, up-to-date information on road conditions, seasonal closures, and entrance requirements for routes that pass through national parks, which is worth checking directly before finalizing travel dates for any of these trips.
