The 12 Best Road Trips in the USA

The short answer

The best road trips in the USA fall into three families: the legendary cross-country routes (Route 66, the Great River Road), the iconic coastal and mountain drives (the Pacific Coast Highway, the Blue Ridge Parkway, Going-to-the-Sun Road), and the national-park loops (the Southwest’s Grand Circle, the Western parks). Pick by how much time you have and what landscape you crave, drive it in the right season, and — because road trips are cheaper and more fun shared — find a co-driver to split the gas and the playlist. Below, the twelve worth building a trip around.

Why the USA owns the road trip

The American road trip is a genre, not just a way to travel — woven into the culture from Kerouac to every coming-of-age movie — and the geography earns it. In a single country you can drive from ocean to desert to alpine peaks to swamp, on a highway system that reaches almost everywhere, past diners, motels, and roadside oddities that exist purely for the passing traveler. In 2026 the pull is stronger than ever: Route 66’s 100th anniversary has sent interest soaring, and searches for outdoor destinations — lakes, mountains, national parks — are up sharply as travelers choose the open road over the crowded airport. The freedom is the feature: your route, your pace, your detours.

The 12 legendary routes

• 1. Route 66 — Chicago to Santa Monica. The Mother Road: ~2,448 miles, 8 states, 2–3 weeks of neon, kitsch, and Americana, celebrating its centennial in 2026. The definitive cross-country trip — full guide in our Route 66 road trip deep-dive.
• 2. Pacific Coast Highway — California’s Highway 1. ~600 miles of cliff-edge Pacific from San Francisco past Big Sur to Los Angeles or San Diego; arguably the world’s most beautiful drive. See our PCH road trip guide.
• 3. The Grand Circle — Southwest national parks. Loop the greatest concentration of parks on Earth: Grand Canyon, Zion, Bryce, Arches, Canyonlands, Monument Valley. The bucket-list park drive — see national parks road trip.
• 4. Blue Ridge Parkway — Virginia to North Carolina. ~469 miles of the Appalachians at 45 mph, unforgettable in October’s fall color. America’s favorite scenic drive.
• 5. Going-to-the-Sun Road — Glacier National Park, Montana. 50 miles of engineering-marvel alpine drama; short but among the most spectacular stretches of tarmac anywhere. (Note Glacier’s 2026 shuttle changes below.)
• 6. Overseas Highway — Miami to Key West. ~113 miles of US-1 hopping across 42 bridges over turquoise water to the end of the road at Key West. Pure tropical Americana.
• 7. The Great River Road — the Mississippi. Follow the river ~2,000 miles from Minnesota to the Gulf through the American heartland, blues towns, and New Orleans.
• 8. The Pacific Northwest loop — Washington & Oregon. Seattle, Mount Rainier, Olympic’s rainforests and coast, the Columbia Gorge, and Oregon’s wild shoreline.
• 9. The Great American West — Yellowstone & the Tetons. Loop the geysers, wildlife, and jagged peaks of Wyoming and Montana — the classic Western parks trip.
• 10. Utah’s Mighty 5. Zion, Bryce, Capitol Reef, Arches, and Canyonlands in one red-rock loop — the most park-dense drive in the country.
• 11. The Southern charm loop — Nashville, Memphis, New Orleans. Music, food, and history through Tennessee, Mississippi, and Louisiana — a road trip you can hear.
• 12. New England’s fall foliage — the Kancamagus & beyond. Vermont, New Hampshire, and Maine ablaze in late September and October; the quintessential autumn drive.

At-a-glance comparison

How to choose your route

1. Start with your days. A long weekend suits the PCH, Going-to-the-Sun, or a foliage loop; one to two weeks unlocks the Grand Circle or the Western parks; three weeks is Route 66 or the Great River Road territory.
2. Pick your landscape. Coast (PCH, Overseas Highway, Oregon), red rock (Southwest), alpine (Glacier, Tetons), forest and foliage (Blue Ridge, New England), or Americana and culture (Route 66, the Southern loop).
3. Match the season hard. This is the make-or-break variable — alpine roads are snow-closed in winter, the Southwest bakes in summer, the Keys shine in winter, and foliage routes have a two-week window. The comparison table above is your calendar.
4. Be honest about pace. Rushing a road trip defeats its purpose. Budget fewer miles per day than you think (250–350 is a pleasant max), and leave room for the unplanned diner and the “what’s down that road?” detour that becomes the best memory.

What a road trip really costs

• Gas is the headline. Estimate total miles ÷ your car’s mpg × local fuel price; a 2,000-mile trip in a 30-mpg car is roughly 67 gallons. Splitting it with a co-driver halves it instantly.
• Accommodation is the swing. Motels and camping keep it cheap; a mix of camping, budget motels, and the occasional splurge is the classic road-trip formula. Book national-park-gateway towns ahead in summer.
• The America the Beautiful pass (~$80/year) pays for itself in three or four national parks and covers everyone in your vehicle — essential for any park-heavy route.
• Car rental & one-way fees. If you’re not driving your own, one-way rentals (fly-in, fly-out different cities) cost more but save backtracking; price it against the round-trip loop.
• The shared-cost math is the road trip’s secret: two or four people splitting gas, car, and rooms turns an expensive trip into a cheap one. More on that below.
