Best Road Trip Routes in the USA: A State-by-State Guide

Few things beat loading up the car and pointing it toward open highway. The USA has an almost unfair concentration of iconic drives: coastal cliffs, red rock canyons, alpine passes, backroads through farmland. Picking the right one matters more than most people realize, because the wrong road for your vehicle, your season, or your pace turns a dream trip into a long detour.

This guide covers the best road trip routes across the country, organized by region, so you can find the drive that fits the trip you can actually take.

Northeast

Maine: Route 1 coastal drive

Route 1 runs roughly 527 miles from Kittery at the New Hampshire border to Fort Kent near Canada, though you do not have to drive all of it. The stretch between Portland and Bar Harbor is the most rewarding, threading through fishing villages, lobster shacks, and the rocky shoreline of Acadia National Park. Late June through September gives you the best weather and ferry access to the offshore islands.

Vermont: Route 100 through the Green Mountains

Route 100 runs the length of Vermont along the spine of the Green Mountains. It is a slow road by design, passing ski towns, covered bridges, and farmland that turns electric in October. This is one of the best fall foliage drives in the country. Budget at least two days.

New York: the Adirondack Trail, Route 30

Route 30 cuts through Adirondack Park, the largest protected area in the contiguous United States. The drive from Amsterdam to Malone passes lakes, trailheads, and small mountain towns, and pairs well with a few nights of camping or a stay at one of the park's lodges.

Mid-Atlantic and Southeast

Virginia and North Carolina: Blue Ridge Parkway

The Blue Ridge Parkway is 469 miles of federally protected scenic road connecting Shenandoah National Park to Great Smoky Mountains National Park. No commercial trucks, no billboards, no traffic lights. Overlooks appear every few miles and the road passes dozens of trailheads. Peak season is late September through mid-October for fall foliage, though spring wildflowers are equally underrated.

Tennessee and North Carolina: Great Smoky Mountains loop

A loop from Knoxville or Asheville gives you Clingmans Dome, Cades Cove, and Newfound Gap Road. This is one of the most visited national park routes in the country, so weekday travel and early starts make a real difference. Gatlinburg, Cherokee, and Bryson City each offer a different entry point.

Florida: US-1 through the Keys

The Overseas Highway from Miami to Key West covers 113 miles over 42 bridges, including the Seven Mile Bridge. Short by road trip standards, but it rewards slow travel: Bahia Honda State Park, snorkelling at John Pennekamp Coral Reef State Park, and sunset at Mallory Square.

Midwest

Michigan: M-119 Tunnel of Trees

This 20-mile stretch along Lake Michigan between Harbor Springs and Cross Village is one of the most beautiful short drives in the Midwest. A canopy of hardwoods arches over the road with glimpses of the lake through the trees. Late September and early October are the sweet spot.

Minnesota: North Shore Scenic Drive, Highway 61

Highway 61 from Duluth to the Canadian border follows Lake Superior for about 150 miles. State parks, waterfalls, and hiking trails line the route, with Split Rock Lighthouse, Gooseberry Falls, and access to the Boundary Waters Canoe Area Wilderness all on the corridor.

South Dakota: Needles Highway and Iron Mountain Road

These two routes in and around Custer State Park are engineering achievements as much as scenic drives. Needles Highway winds through granite spires and tunnels barely wide enough for a standard car. Iron Mountain Road uses pigtail bridges and tunnels framed to put Mount Rushmore in view. Combine them with US-240 through the Badlands for a full Black Hills loop.

Southwest

Arizona: Highway 89A through Oak Creek Canyon

The drive from Flagstaff to Sedona drops 2,000 feet through Oak Creek Canyon in about 12 miles. Red sandstone walls, creek crossings, and swimming holes make it one of the most scenic short drives in the Southwest, with Sedona and its trailheads at the far end.

Utah: Highway 12 scenic byway

Highway 12 is consistently ranked among the most scenic roads in the country, connecting Bryce Canyon to Capitol Reef through 124 miles of slickrock, canyon country, and high-altitude forest. The Hogback section, where the road rides a narrow ridge with drops on both sides, is one of the most dramatic stretches of pavement in the USA.

New Mexico: Enchanted Circle scenic byway

An 84-mile loop north of Taos through the Sangre de Cristo Mountains, Taos Ski Valley, and the high desert of the Rio Grande del Norte National Monument. Compact, varied, and it works as either a day loop or a two-night base trip from Taos.

Nevada and Utah: US-50, the Loneliest Road in America

US-50 crosses Nevada from Fernley to the Utah border through 287 miles of basin and range country, with towns like Austin and Ely spaced 80 to 100 miles apart. This is a route for travellers who want genuine solitude and a real sense of how vast the interior West is. Carry extra fuel and water.

Mountain West

Colorado: San Juan Skyway

A 236-mile loop in southwestern Colorado through Durango, Silverton, Ouray, Telluride, and Cortez. The Million Dollar Highway between Ouray and Silverton is carved into cliff faces above old mining valleys. Late July through September is when the high passes are reliably clear of snow, and several serious hiking areas sit along the route.

Wyoming and Montana: Beartooth Highway, US-212

The Beartooth climbs to nearly 11,000 feet between Red Lodge, Montana and Cooke City at Yellowstone's northeast entrance. Open only from late May through October. Above treeline the views stretch for miles over alpine tundra and snowfields.

Idaho: Sawtooth scenic byway, Highway 75

Highway 75 through the Sawtooth National Recreation Area connects Shoshone to Stanley through 117 miles of river valley and mountain scenery, with the Sawtooth Range rising to the west and the Salmon River alongside much of the route.

Pacific Coast and Northwest

California: Pacific Coast Highway, Highway 1

Highway 1 earns its reputation. The stretch between San Francisco and Los Angeles passes Big Sur, Hearst Castle, Morro Bay, and dozens of state parks. Big Sur alone can absorb two or three days. Sections of Highway 1 close after slides, so checking road conditions before you leave is worth the two minutes.

Oregon: US-101 along the coast

Oregon's section covers about 363 miles from Astoria to Brookings. Unlike California, Oregon's coast is largely undeveloped, with state parks every 20 to 30 miles and free beach access throughout. Cannon Beach, the Oregon Dunes, and Cape Perpetua are the highlights, and crowds stay manageable even in summer.

Washington: North Cascades Highway, Highway 20

Open roughly late April through November, when snow closes the high passes. The drive from Burlington to Winthrop passes glaciated peaks, turquoise lakes, and the Washington Pass overlook. On the eastern side the landscape shifts quickly to dry ponderosa forest and the Methow Valley, one of the most abrupt and satisfying transitions on any American road.

Alaska: Parks Highway, AK-3, to Denali

The Parks Highway from Anchorage to Fairbanks passes the Denali National Park entrance at mile 237. About 360 miles, six to eight hours without stops, though the wildlife makes stopping the obvious call. The park road inside Denali is accessible only by bus beyond the first 15 miles, which adds a full day.

Quick reference by travel style

Turning a route into a plan

Most road trips fall apart in the planning phase, not on the road. Sequencing driving legs, campsites, fuel stops, and activities across several days is genuinely complicated when the answers live on a dozen different sites.

Describe the trip to Xavier in plain language, including your starting point, dates, group size, vehicle, and what you want to do, and you get a day-by-day Xpedition with driving legs, trailheads, campsites, accommodations, fuel stops, and meal stops organized into one connected journey with an interactive map. Each waypoint opens in your preferred navigation app. Xplorer Pro, at $14.99 per month or $99 per year, adds unlimited saved Xpeditions, editing and sharing, a connected booking log for confirmation numbers, and Xavier's memory of your preferences across future trips.

Frequently asked questions

What is the best road trip route in the USA for first-timers?

The Pacific Coast Highway between San Francisco and Los Angeles is a strong first road trip: well-marked, services are easy to find, and the scenery is consistently rewarding. The Blue Ridge Parkway is the equivalent choice if you prefer mountains to coast.

Which US road trip routes are best for camping?

The Blue Ridge Parkway, Highway 12 in Utah, and the North Shore Scenic Drive in Minnesota all have campgrounds along or near the route. The San Juan Skyway has strong camping access through the surrounding national forests.

What is the best time of year for a US road trip?

It depends on the region. The Southwest is best in spring and fall. The Pacific Coast is good year-round but clearest in late summer. Mountain routes like the Beartooth Highway and North Cascades Highway are only open from late spring through early fall. The Blue Ridge Parkway peaks in late September and early October for fall foliage.

How do I plan a multi-state road trip without it becoming overwhelming?

Breaking the trip into daily driving legs of 150 to 250 miles keeps it manageable. Decide where you are sleeping before you fill the days with activities, and leave one flexible day per week for weather and closures.

Which US road trip routes suit high-clearance or 4WD vehicles?

Needles Highway in South Dakota and parts of the San Juan Skyway are paved but narrow. For unpaved routes, the Mojave Road in California, the Dalton Highway in Alaska, and the side routes off US-50 in Nevada all reward high clearance. Always check current road conditions before heading off pavement.

Are there good road trip routes for travelling with dogs?

Oregon's US-101 has many dog-friendly beaches and state parks. The North Shore Scenic Drive and Vermont's Route 100 also have trail access that welcomes dogs. Check individual park rules first, since many national park trails restrict them. The dog-friendly hiking trails guide covers where access actually holds up.

How far in advance should I book accommodation on popular routes?

For the Pacific Coast Highway, Blue Ridge Parkway, and Yellowstone-adjacent routes in summer, three to six months ahead is reasonable for peak weekends. Off-season and weekday nights are much easier. Campsite reservations on popular routes can fill within minutes of the booking window opening.

Pick the road that fits the trip you can take

The USA has enough great road trip routes to fill several lifetimes. The useful filter is not which one is objectively best, it is which one matches the window you actually have, the vehicle you actually drive, and the pace you actually enjoy.

Start with the region that fits your next free week, pick a route your vehicle and comfort level can handle, and build the days around what you want to do rather than how far you could theoretically drive. The road is already there. The planning just needs to catch up.
