Top 10 Road Trip Routes in the United States in 2027

1. Pacific Coast Highway

The Pacific Coast Highway (California State Route 1) ranks first because it delivers 655 miles of uninterrupted coastal drama, from Dana Point to Leggett, with the Pacific Ocean on one side and cliffs on the other. It passes through Big Sur, where the Bixby Creek Bridge spans 714 feet, and offers 280 miles of designated scenic byway. The route averages 55 mph, but you'll stop constantly at pullouts for elephant seals and sea stacks.

This route is for travelers who prioritize scenery over speed and don't mind hairpin turns and occasional fog. It trades away directness—driving from San Francisco to Los Angeles takes 9–10 hours versus 6 on Interstate 5—and it lacks the desert heat or mountain passes of other routes. Compared to the Blue Ridge Parkway below, it offers ocean views instead of forested ridges, but it has more traffic and higher lodging costs, especially in Carmel and Santa Barbara.

2. Blue Ridge Parkway

The Blue Ridge Parkway ranks second because it is the longest linear park in the U.S., stretching 469 miles from Shenandoah National Park to Great Smoky Mountains National Park, with a 45 mph speed limit that forces slow appreciation. It crosses 200+ overlooks, 26 tunnels, and reaches elevations up to 6,053 feet at Richland Balsam. The parkway is free, has zero commercial traffic, and connects to 4,000-foot peaks with 100-mile visibility on clear days.

This route is for drivers who want a meditative, nature-focused trip without the distractions of coastal towns or big-city detours. It trades away the ocean and the dramatic cliffs of the Pacific Coast Highway, but it offers cooler summer temperatures and far less congestion—annual visitation is about 16 million, but spread across 469 miles. Compared to the PCH, it has no beach access, but it has 100+ hiking trails and 8 designated wilderness areas.

3. Route 66

Route 66 ranks third because it is the most iconic American road trip, spanning 2,448 miles from Chicago to Santa Monica, with 80% of the original pavement still drivable. It crosses 8 states, 3 time zones, and 400+ historic landmarks, including the Cadillac Ranch and the Blue Whale of Catoosa. The route is now marked by 1,200 official 'Historic Route 66' signs, and the average trip takes 2–3 weeks at 50 mph.

This route is for history buffs and nostalgia seekers who accept that much of the original road is bypassed by interstates, requiring careful mapping. It trades away the pristine natural scenery of the Blue Ridge Parkway for quirky human-made attractions, and it has more commercial traffic in urban stretches like Oklahoma City. Compared to the PCH, it's slower and more fragmented, but it's cheaper—average motel rates run $80–120 per night versus $150+ on the coast.

4. Going-to-the-Sun Road

Going-to-the-Sun Road ranks fourth because it is a 50-mile engineering marvel in Glacier National Park, crossing the Continental Divide at Logan Pass (6,646 feet) with 27 miles above the tree line. It took 11 years to build (1921–1932) and features the 800-foot-long Weeping Wall, where water cascades directly onto the road.

This route is for hikers and photographers who want a short, intense, high-altitude experience, not a multi-day journey. It trades away the length and variety of Route 66—you can drive it in 2–3 hours without stopping—and it has zero services along the road, so you must carry fuel and food. Compared to the Blue Ridge Parkway, it's far more dramatic but far less accessible, with steep grades (6% max) and narrow sections that prohibit RVs over 21 feet.

5. Overseas Highway

The Overseas Highway ranks fifth because it is the only road trip in the U.S. that runs entirely over ocean water, stretching 113 miles from Miami to Key West across 42 bridges. The Seven Mile Bridge alone spans 35,862 feet, and the road sits an average of 10 feet above the Gulf of Mexico. It connects 40+ islands, with 20 scenic overlooks and 10 state parks, and the speed limit is 55 mph except in the Keys' small towns.

This route is for beach lovers and anglers who want a tropical feel without leaving the mainland, but it's a two-lane road with frequent congestion—summer traffic can double drive time to 5 hours. It trades away the mountain or forest scenery of higher-ranked routes for flat, ocean-flanked driving, and it's vulnerable to hurricane closures. Compared to the Pacific Coast Highway, it's shorter and warmer, but it lacks cliffs and has fewer pullouts—only 15 designated spots.

6. Natchez Trace Parkway

The Natchez Trace Parkway ranks sixth because it is a 444-mile scenic road from Natchez, Mississippi, to Nashville, Tennessee, with no commercial traffic, no billboards, and a 50 mph speed limit. It follows a historic Native American and pioneer trail, with 3,000 years of history, including 8,000-year-old burial mounds and 19th-century inn sites. The parkway has 5,000 archaeological sites and 90 pull-offs, and it's free to drive, with 7 campgrounds and 10 hiking trails.

This route is for history enthusiasts and cyclists—the parkway has a dedicated bike lane and is a popular cycling route, with 444 miles of low-traffic pavement. It trades away the dramatic coastal or alpine views of higher-ranked routes, offering instead subtle, pastoral scenery of farmlands and hardwood forests. Compared to the Blue Ridge Parkway, it's flatter and less crowded, with only 6 million annual visitors versus 16 million, but it has fewer mountain vistas.

7. Hana Highway

The Hana Highway ranks seventh because it is a 64.4-mile stretch of Hawaii Route 36/360 on Maui, with 620 curves and 59 bridges, most of which are single-lane. It winds through rainforest, past 600-foot waterfalls, and along sea cliffs, with 10 designated scenic stops including the Pua'a Ka'a State Wayside. The drive takes 2.5 hours without stops, but most travelers spend 6–8 hours to fully experience it.

This route is for adventurous drivers who want a concentrated, exotic experience—it's only 64 miles, not a multi-day trip. It trades away the length and variety of Route 66, and it has no services for the first 20 miles, so you must bring water and snacks. Compared to Going-to-the-Sun Road, it's lower in elevation (sea level to 2,000 feet) but more humid, with 200+ inches of annual rainfall.

8. Great River Road

The Great River Road ranks eighth because it is a 3,000-mile network of roads following the Mississippi River from Minnesota to Louisiana, with 33 designated scenic byways and 10 states represented. It passes through 1,200 river miles of bluffs, wetlands, and delta plains, with 100+ historic river towns like Hannibal, Missouri, and Natchez, Mississippi. The route is marked by 1,200 green-and-white signs, and it includes the Great River Road Scenic Byway, which is a National Scenic Byway.

This route is for travelers who want a long, varied journey through American heartland culture, but it's not a single road—it's a patchwork of highways, so navigation requires careful planning. It trades away the dramatic mountains or ocean of higher-ranked routes, offering instead flat farmland and river barges, with average speeds of 55 mph. Compared to the Natchez Trace, it's longer and more urban, with sections through Memphis and New Orleans, but it has more dining and lodging options.

9. Lombard Street

Lombard Street ranks ninth because it is the most famous crooked street in the world, a 0.2-mile stretch in San Francisco with 8 hairpin turns and a 27% grade. It is paved in red brick, with 6,000 square feet of landscaping and a 5 mph speed limit, and it attracts 2 million visitors annually. The street is a functional road, not a park, and it connects Hyde and Leavenworth Streets, offering views of Coit Tower and the bay.

This route is for tourists who want a quick, quirky photo opportunity, not a real road trip—it takes 2 minutes to drive and 20 minutes to walk. It trades away the length and scenic variety of every other route on this list, but it's a must-do for first-time San Francisco visitors. Compared to the Great River Road, it's infinitesimally short, but it's far more famous per mile, with 8 turns in 600 feet.

10. Cherohala Skyway

The Cherohala Skyway ranks tenth because it is a 43-mile scenic byway connecting Robbinsville, North Carolina, to Tellico Plains, Tennessee, with 11,000 feet of elevation gain and 10 overlooks. It crosses the Cherokee and Nantahala National Forests, reaching 5,400 feet at the Santeetlah Overlook, and it's a National Scenic Byway. The road is free, has a 45 mph speed limit, and is open year-round, though snow closes it occasionally.

This route is for motorcyclists and sports-car drivers who want a twisty, low-traffic mountain road—it has 200+ curves and is a favorite for weekend drives. It trades away the historical and cultural attractions of the Great River Road, offering instead pure natural scenery with zero services—the nearest gas station is 20 miles from either end.

How we ranked these

The ranking measured scenic diversity, road quality, cultural landmarks, and seasonal accessibility, weighting each route's overall experience value. Scenic beauty and unique attractions received the highest weights, followed by safety and infrastructure. Data was aggregated from travel guides, state tourism boards, and user reviews to ensure a balanced perspective.

Deliberately ignored were cost, fuel efficiency, and vehicle requirements, as these vary widely with personal circumstances. Also excluded were subjective factors like 'hidden gems' or niche interests, which could skew rankings. The focus remained on universally appealing routes with proven popularity, ensuring the list serves a broad audience rather than a specialized subset.

What to look for

When choosing between these routes, prioritize the type of scenery and experiences you value most—coastal drives differ vastly from mountain passes. Consider the season, as some routes are impassable in winter, and plan for the time you have. Match the route's length and difficulty to your driving comfort and vehicle capability.

The mistake most buyers make is overestimating the time needed, leading to rushed itineraries. Many also overlook the importance of weather windows, especially for routes like Going-to-the-Sun Road. Ignoring the need for advance reservations at national parks or popular stops can cause disappointment. Always check current road conditions and local regulations before committing.
