East Coast National Parks Road Trip: Maine to the Florida Keys

The East Coast has seven National Parks strung from the granite of Maine to a brick fort 70 miles past Key West, and you can link them in one drive of about 2,350 miles. The surprise is how much the climate changes on the way: you start in spruce and cold salt water and finish in sawgrass and coral.

The trick is timing. Leave Acadia in fall and drive south, and you run ahead of winter the whole way, reaching Florida as its dry season begins. This post covers the road, the miles, and the days. Each park gets a short plan here, and the full days are in my guides.

East Coast National Parks Road Trip at a Glance

• Parks: Acadia, Shenandoah, Great Smoky Mountains, Congaree, Biscayne, Everglades, and Dry Tortugas.
• Start and finish: Bar Harbor, Maine, to Key West, Florida (one way).
• Driving: about 2,350 miles one way, plus the driving inside the parks.
• Time behind the wheel: about 40 hours, spread over the trip.
• How many days: 14 at the least, 21 to 24 to enjoy it.
• Best seasons: mid-September through early December, driving south.
• Pass: the $80 America the Beautiful annual pass covers the parks that charge, and the Dry Tortugas ferry gives a credit for it. Congaree, Biscayne, and the Smokies charge no entrance fee, though the Smokies require a parking tag.

How Many Days Do You Need?

I'd plan on 22 days. Here's the math. Long drives between regions eat 7 days: two from Maine to Virginia, one to the Smokies, one to Congaree, two to Homestead, and one to Key West. The parks need about 13 more: 3 at Acadia, 2 at Shenandoah, 3 in the Smokies, 1 at Congaree, 1 at Biscayne, 2 at Everglades, and 1 at Dry Tortugas. Add 2 spare days, because a boat is involved at both Biscayne and Dry Tortugas, and boats cancel.

In 14 days you can see all seven, but only by giving most parks a single day and driving 7 hours on the transfer days. If you have 10 days or fewer, split the trip. Acadia to the Smokies is one vacation, and Congaree to the Keys is another.

Which Direction to Drive It

South, in fall. Acadia's color generally peaks in mid-October, the Blue Ridge and the Smokies follow it down the mountains, Congaree's color comes around late October and early November, and South Florida's dry season starts about November or December. Driven north in spring, the trip works too, but you'd arrive in Maine before much has opened; the Park Loop Road doesn't open until April 15.

Fly into Bangor or Boston (about 280 miles from Bar Harbor, 5 hours) and fly home from Key West or Miami, about 160 miles from Key West. This is a one-way rental across a long distance, so get the drop fee in writing before you commit. It can be cheaper to rent two cars, one for each half, than to pay one big fee.

The Route, Leg By Leg

Acadia: Bar Harbor and Mount Desert Island

Your first park needs no drive at all once you're there. Acadia's Park Loop Road and Cadillac summit road close to cars from December 1 to April 14, apart from two short sections. In 2026 the summit road needed a $6 vehicle reservation from May 20 through October 25, on top of the entrance pass, so check the dates for your year.

A short plan for Acadia: Start at the Hulls Cove Visitor Center with lunch in the car. Follow the Park Loop Road to Sand Beach, walk Ocean Path to Thunder Hole and back, and stop at an Otter Cliffs viewpoint. Jordan Pond is your turnaround and your lunch stop; the Jordan Pond House is seasonal, so carry a backup. Full days are in my Acadia National Park guide.

Bar Harbor to Front Royal: About 830 Miles, 13.5 Hours

Split this into two days. Take Maine 3 and U.S. 1A to Bangor, Interstate 95 to Portland and on into Massachusetts, then the Massachusetts Turnpike to Interstate 84 at Sturbridge. Follow I-84 through Hartford and across New York to Scranton, and take Interstate 81 south through Pennsylvania and Maryland. Interstate 66 east reaches Front Royal. This line skirts New York City and Washington, which is the whole point of it. Expect tolls in Maine, New Hampshire, and Massachusetts.

Skyline Drive: 105 Miles, 3 to 4 Hours

Shenandoah's Skyline Drive is the only way along the park's ridge, and parts close in bad weather. It's slow by design, so don't count it as a transfer. Note Marys Rock Tunnel's height clearance if you're in an RV. The park has been cashless at its entrance stations since July 2025, and a private vehicle pays $30 for seven days. Skyland closes for the season in early November; the 2026 date was November 8.

A short plan for Shenandoah: Enter at Front Royal and drive south to the Stony Man parking area, about mile 42. Walk the 1.6-mile round trip to the cliffs, then get grab-and-go food at Skyland, open spring through fall. Big Meadows, at mile 51, is a day visitor's turnaround; on this route you'll keep rolling toward Rockfish Gap. Full days are in my Shenandoah National Park guide.

Rockfish Gap to Gatlinburg: About 340 Miles, 5.5 Hours

Interstate 64 west drops you to Interstate 81, and I-81 runs southwest down the Great Valley of Virginia into Tennessee. Take Interstate 40 west to exit 407, then Tennessee 66 and U.S. 441 through Sevierville and Pigeon Forge to Gatlinburg. U.S. 441 through those towns is slow, especially on fall weekends. The Blue Ridge Parkway looks like the obvious choice on the map, and in fall 2026 it was still recovering from Hurricane Helene. The Park Service listed work at 45 remaining sites as of September 2026, estimated to finish by the end of the year, so check that page before you plan on it.

The Smokies charge no entrance fee, but every vehicle parked for more than 15 minutes needs a parking tag: $5 a day or $15 a week at research time. Most trailheads don't have pay machines, so buy one first.

A short plan for Great Smoky Mountains: Stop at Sugarlands Visitor Center for your parking tag and maps, and bring lunch, since the park has no restaurants. Climb Newfound Gap Road to the gap and step onto the Appalachian Trail. Then take Kuwohi Road, closed in winter, walk the steep paved path to the tower, your turnaround, and picnic on the way down. Full days are in my Great Smoky Mountains National Park guide.

Gatlinburg to Congaree: About 260 Miles, 4.5 to 5 Hours

Newfound Gap Road takes you across the park to Cherokee (about 33 miles, 1 hour). From there, U.S. 74 and Interstate 40 run to Asheville, and Interstate 26 drops out of the mountains to Columbia. Interstate 77 south to exit 5 connects to Bluff Road. Put 100 National Park Road, Hopkins, SC 29061 into your GPS, since some devices misroute you if you type the park's name.

Congaree has no entrance fee, no lodging, and no food service. The river overflows into the floodplain about ten times a year, so check Congaree National Park alerts before you go. The visitor center's hours are on the park's site, and it closes on some holidays, including Thanksgiving.

A short plan for Congaree: Start at the Harry Hampton Visitor Center and ask what the water is doing. Fill your bottles, then walk the 2.6-mile Boardwalk Loop through the bald cypress to the Weston Lake overlook, your far point, and finish the loop back. There's no food in the park, so bring lunch or eat in Gadsden. Full days are in my Congaree National Park guide.

Columbia to Homestead: About 680 Miles, 10 Hours

Take Interstate 26 east to Interstate 95, and I-95 south through Savannah and Jacksonville. Florida's Turnpike carries you past Miami to Homestead. Make it two days, with a night around Savannah or Daytona Beach. Traffic around Miami can add an hour or more.

Homestead: Biscayne and Everglades

Homestead and Florida City are your base for both parks. Biscayne's headquarters at Convoy Point is about 7 miles from town, at the end of SW 328th Street. There's no entrance fee, and you can't drive to the islands, so book a boat trip first or the day ends at the jetty. Everglades' main entrance is on Palm Drive west of town. It's cashless, and a private vehicle paid $35 in 2026, good for seven days. Flamingo is 38 miles beyond the entrance, and a round trip is about 76 miles.

A short plan for Biscayne: Book a boat before anything else. Check in at Convoy Point, fill your bottles, and ride across the bay to Boca Chita Key, your turnaround. Look at the lighthouse if staff have it open, walk the short trail, and eat the lunch you brought, since the park has no restaurant. Full days are in my Biscayne National Park guide.

A short plan for Everglades: Use the Homestead entrance on Palm Drive and stop at the Ernest F. Coe Visitor Center. Walk the Anhinga Trail and Gumbo Limbo Trail at Royal Palm, eat the lunch you packed, and drive the Main Park Road to Pa-hay-okee for the River of Grass. Mahogany Hammock is your turnaround unless you're going on to Flamingo. Full days are in my Everglades National Park guide.

Homestead to Key West: About 125 Miles, 3 to 3.5 Hours

U.S. 1 is the only road. It crosses the Keys on the Overseas Highway, mostly two lanes, with low speed limits through the towns. There's no passing your way out of a slow day, so leave time.

Key West to Dry Tortugas: 70 Miles of Open Water

Your car stays in Key West. The park has one ferry and one seaplane operator: the Yankee Freedom ferry gives you about 4.5 hours in the park, and Key West Seaplane Adventures takes about 40 minutes each way. Book well ahead, and leave a spare day, because winter cold fronts cause rough crossings and cancellations. There's no food, water, fuel, or cell service in the park; the ferry feeds its day visitors.

A short plan for Dry Tortugas: The ferry lands you at Garden Key, and the sally port is the only way into Fort Jefferson. Take the ferry's tour, go back aboard for lunch, then climb to the top of the walls. Walk the moat wall, turning back at any barricade, and finish at the south swim beach. Full days are in my Dry Tortugas National Park guide.

Where to Stay Along the Way

• Acadia: Bar Harbor has the most rooms and restaurants. Southwest Harbor suits the quieter west side.
• Shenandoah: Skyland and Big Meadows Lodge are the park's lodges. Front Royal, Luray, and Waynesboro sit outside.
• Great Smoky Mountains: Gatlinburg and Townsend on the Tennessee side, Cherokee in North Carolina. LeConte Lodge is the only lodging in the park, reached only on foot.
• Congaree: Columbia, about 20 minutes away, has plenty of hotels. The park has only two small tent campgrounds.
• Biscayne and Everglades: Homestead and Florida City serve both. Flamingo Lodge is inside Everglades, 38 miles from the entrance.
• Dry Tortugas: Key West, the priciest stop on the trip. The only overnight in the park is primitive camping on Garden Key.

Best Time of Year to Drive It

Mid-September through early December is the window this route is built for. The risk at the far end is hurricane season, which runs through November 30, so keep your Florida bookings flexible and watch the forecast.

Summer works in Maine, Virginia, and the Smokies, but Congaree's heat index can exceed 110, and South Florida brings mosquitoes and storms. Winter reverses the problem: the Keys are at their best, while Acadia's main road is closed and Skyline Drive closes at times. Spring works better driven north, with wildflowers in Shenandoah and the Smokies, though you'd reach Acadia early.

Road Trip Tips for the East Coast

• Book the boats first. Everything else on this trip can be moved a day. A sold-out Dry Tortugas ferry can't.
• Carry a card. Shenandoah, Everglades, and Dry Tortugas are cashless.
• Check each park's seasonal closures for your exact dates. Fall is when services start shutting down in the north, one by one.
• Avoid the I-95 corridor at rush hour. Time your Hartford and Miami arrivals around it.
• Pack for 50 degrees of difference. You'll want a fleece on Cadillac and a sun shirt at Fort Jefferson.
• Bring your own food on the park days in Congaree, Biscayne, and the Smokies. None of them sells a meal.

Plan Your Days Inside Each Park

This post gets you from park to park, with a short plan for each stop. The full days are what my guides are for: each one has nine itineraries for one, two, or three days at easy, moderate, and strenuous effort, each with a backup plan for bad weather or a closure, plus orientation maps, the park's history, and the animals you're likely to see. You get an EPUB and a printable PDF, so the day's plan can ride in the car with you.

East Coast National Parks Road Trip FAQ

Can I drive to Dry Tortugas? No. It's 70 miles of open water past Key West, so you go by ferry, seaplane, or private boat.

Is Biscayne worth a stop without a boat? Only as a short one. About 95 percent of the park is water, so without a boat trip you'll see the visitor center and the jetty. Book a boat if you can.

Can I add other parks? Yes. New River Gorge sits west of Interstate 81 by way of Interstate 64, and it adds at least two days.

Do I need reservations to enter these parks? Not to enter any of the seven as of November 2026, but the Cadillac summit road, boats, and campgrounds need their own. Check Acadia National Park alerts and Dry Tortugas National Park alerts before you lock in dates.
