Popular US Road Trip Routes

The United States has some of the most spectacular road trip routes in the world — from coastal highways and mountain passes to desert roads and forested byways. Each route has its own character, its own best season, and its own weather challenges.

Below, we've profiled some of the most popular and rewarding road trips in the country. For each route, you'll find weather insights, best times to go, and practical tips. Before you depart, use WeatherWeGo to check real-time conditions along your specific route and departure date.

One of the most iconic drives in America, Highway 1 hugs the California coastline through Big Sur, passing towering cliffs, secluded beaches, and charming coastal towns. The stretch through Big Sur is widely considered one of the most scenic drives in the world.

Route Highlights

• Bixby Bridge — the iconic single-span arch bridge overlooking the Pacific
• Big Sur — 90 miles of rugged, undeveloped coastline
• Hearst Castle — the opulent hilltop estate in San Simeon
• McWay Falls — an 80-foot waterfall dropping directly onto the beach
• Santa Barbara — the "American Riviera" with Spanish architecture
• Monterey and Carmel-by-the-Sea — charming seaside communities

Practical Tips

• Drive north to south for the best ocean views (you'll be on the cliff side)
• Plan at least 2 days to enjoy the scenery — rushing through defeats the purpose
• Gas stations are scarce in Big Sur — fill up before entering
• Check for road closures on Caltrans before departing, especially after winter storms
• Morning fog often clears by 11 AM — no need to rush an early departure

The "Mother Road" spans eight states from the shores of Lake Michigan to the Pacific Ocean. While the original Route 66 has been largely replaced by interstate highways, much of the historic route is still drivable and lined with retro diners, neon signs, ghost towns, and Americana charm.

Route Highlights

• Cadillac Ranch — half-buried Cadillacs in Amarillo, TX
• The Painted Desert and Petrified Forest in Arizona
• The Grand Canyon (short detour from Williams, AZ)
• Meramec Caverns in Missouri
• The Blue Whale of Catoosa in Oklahoma
• Santa Fe, NM — art galleries and adobe architecture

Practical Tips

• Avoid the desert sections in July-August unless your car and A/C are in perfect condition
• Spring and fall offer the most comfortable temperatures across the entire route
• Carry extra water and snacks — there are long stretches with no services
• Many historic Route 66 attractions are small businesses with irregular hours
• Download offline maps for areas of New Mexico and Arizona with no cell service

Known as "America's Favorite Drive," the Blue Ridge Parkway winds along the crest of the Blue Ridge Mountains through Virginia and North Carolina. With a 45 mph speed limit and no commercial traffic, it's designed for scenic enjoyment, not speed.

Route Highlights

• Milepost 0-115: Shenandoah Valley overlooks and Virginia farmland
• Peaks of Otter (milepost 86) — mountain lake and hiking trails
• Linn Cove Viaduct (milepost 304) — engineering marvel hugging the mountainside
• Grandfather Mountain (milepost 305) — mile-high swinging bridge
• Mount Pisgah and the Balsam Mountains
• Fall foliage — peak color from early October (north) to late October (south)

Practical Tips

• For fall foliage, visit early-to-mid October at higher elevations, late October at lower elevations
• Start early to avoid afternoon clouds and storms that roll in on summer days
• Gas and services are not available on the Parkway itself — exit at towns along the way
• The Parkway has no shoulders in many sections — use designated overlooks to stop
• Check NPS.gov for real-time closures — segments close regularly for weather and maintenance

One of the most popular day trips or weekend getaways in the Southwest, this route takes you from the neon lights of the Strip to one of the seven natural wonders of the world. The drive itself transitions from desert basin to the forested Kaibab Plateau.

Route Highlights

• Hoover Dam — an engineering marvel and National Historic Landmark
• Historic Route 66 through Kingman and Seligman, AZ
• Williams, AZ — "Gateway to the Grand Canyon" with Route 66 charm
• Grand Canyon South Rim — arguably the most spectacular vista in North America
• Desert landscapes transitioning to ponderosa pine forests

Practical Tips

• In summer, depart Las Vegas by 6 AM to avoid the worst heat
• Carry at least 1 gallon of water per person, more in summer
• The Hoover Dam bypass bridge offers stunning views but can be very hot — visit early
• Reserve Grand Canyon lodging well in advance — it sells out months ahead
• Check your route weather on WeatherWeGo — conditions vary dramatically with elevation changes

New England in autumn is world-famous for a reason. A loop through Vermont, New Hampshire, and Maine takes you through covered bridges, white-steepled churches, farm stands, and mountainsides ablaze with red, orange, and gold.

Route Highlights

• Kancamagus Highway (NH) — 34 miles through the White Mountains
• Stowe and Smugglers' Notch, Vermont
• The Green Mountains of Vermont with farm stands and cider mills
• Acadia National Park, Maine (if extending the loop)
• Covered bridges throughout Vermont and New Hampshire
• Ben & Jerry's Factory in Waterbury, VT

Practical Tips

• Peak foliage varies by two weeks or more depending on the year — check foliage reports
• Weekends in October are extremely crowded on popular routes — go mid-week if possible
• Book lodging well in advance — popular inns and B&Bs sell out by summer
• Pack layers — you may experience 30°F mornings and 60°F afternoons on the same day
• The Kancamagus Highway has no gas stations or services along its 34-mile stretch

US Route 1 through the Florida Keys is unlike any other drive in America. The Overseas Highway connects a chain of tropical islands via 42 bridges, including the famous Seven Mile Bridge, with turquoise water on both sides.

Route Highlights

• Seven Mile Bridge — the longest bridge on the route with stunning ocean views
• Key Largo — "Diving Capital of the World" with John Pennekamp Coral Reef State Park
• Islamorada — sport fishing capital of the world
• Bahia Honda State Park — consistently rated among the best beaches in the US
• Key West — Duval Street, Hemingway House, sunset at Mallory Square

Practical Tips

• Check for traffic before departing — the two-lane stretches create bottlenecks, especially on weekends
• Fill up in Florida City or Key Largo — gas gets progressively more expensive heading south
• The drive can be deceptively tiring due to the long straight bridges and sun glare on water
• Bring polarized sunglasses — essential for reducing water glare
• In hurricane season, always have an evacuation plan and monitor weather closely

• Check weather 1-2 days before departure for the most accurate forecast. Weather predictions beyond 7 days are unreliable for trip planning.
• Mountain weather changes rapidly. Even in summer, mountain passes can have cold temperatures, fog, and sudden storms. Pack layers and be prepared for conditions 20-30°F cooler than nearby cities.
• Coastal routes have their own weather. Marine layer fog, sea breezes, and salt spray are common. Morning fog on the coast often clears by midday.
• Desert heat is no joke. Carry extra water, check your cooling system, and plan to drive early in the day. If your car overheats, pull over immediately — driving with an overheating engine can cause catastrophic damage.
• Weather varies by elevation. A route that takes you from sea level to 10,000 feet will cross multiple climate zones. Use WeatherWeGo to see conditions at each point along your route.
