The East Coast road trip from Boston to Key West

An East Coast road trip from Boston to Key West through nine stops is about 1,735 miles and about 35 hours of driving by our own routing, before traffic. We suggest 16 nights. That is our judgement, not official advice. The stops are Boston, New York City, Philadelphia, Washington, D.C., Charleston, Savannah, St. Augustine, Miami and Key West.

The route is mostly I-95, and the hire car is where it gets awkward. Florida's Turnpike treats rental cars differently, and the Park Service advises against driving in Boston. We read the figures below on 5 November 2026 on the Park Service, NOAA, Florida's Turnpike, the Florida Keys tourism council and the authorities named in each section. Our guides to renting a car in the USA and driving in the USA as a visitor cover the counter and the road.

How far is it from Boston to Key West, leg by leg?

The Boston to Key West road trip is eight legs, and one of them, Washington, D.C. to Charleston, is about 536 miles. The distances and times in the table come from our own routing, a free-flow car profile with no traffic. We rounded the times down to five minutes. No official source gives a drive time for any of these legs.

Our free-flow times ignore city traffic. The Northeast corridor and Miami will be slower in practice, so treat the 35 hours as a floor. The only official comment on delays is the Florida Keys council's line on the road to Key West: traffic can build at peak times.

Philadelphia and Washington, D.C. have no city guide here yet. Our pages for Pennsylvania and Washington, D.C. cover them.

How many nights does an East Coast road trip itinerary need?

An East Coast road trip itinerary of nine stops needs 16 nights by our reckoning, two or three in the biggest cities and one in the smaller ones. The split below is our judgement, built on the legs above, and not an official figure.

The New York to Miami drive is about 1,360 miles and about 26 hours at free-flow, from the table above. Within it, the Washington to Charleston day is the one to plan around. At about 10 hours before stops it needs an early start, and a night in between is a sensible alternative. Our guides to Boston, New York City and Miami cover what each city needs.

Should the car start in Boston, or only after Washington, D.C.?

We suggest picking the car up in Washington, D.C. and taking the train for the northern legs, which cuts the driving to about 1,290 miles by our arithmetic. That is our suggestion, not an official one: we found no official statement that a car is a burden in New York City. The reasons are what a hire car meets in Boston and New York.

For Boston, the Park Service says: "Driving in Boston can be difficult; we strongly suggest that you take public transit." The same page says many subway stations have car parks at $2 to $15 for the day. It puts the Charlestown Navy Yard garage at $25 a day.

For New York, NYC DOT's meter rates start at $5.50 for the first hour in the Midtown Core and Lower Manhattan zone, and $9.00 for the second. South of 96th Street the rates are $5.00 and $8.25. NYC DOT also says all of New York City is a designated tow-away zone and double parking is illegal at all times. We could not read the MTA's page on the congestion toll, so we print no figure for it. Our guide to New York City has the rest.

The Northeast Regional covers the same legs. On the timetable dated 2 November 2026, northbound train 86 (Monday to Friday) shows Washington at 8:50 a.m. and Philadelphia at 10:51 a.m. It shows New York at 12:37 p.m. and Boston at 4:52 p.m. That is about 8 hours end to end by our subtraction. We read this one train and no Amtrak fare, so check the southbound times. The plan: take the train south from Boston to Washington, then hire the car for the 536-mile drive to Charleston.

What do tolls cost a hire car on the East Coast?

A hire car on this route pays its tolls through the rental company, and the rule is strictest in Florida. Florida's Turnpike says toll-by-plate "is not available for customers in rental cars". That leaves two ways to pay: the hire company's toll programme, or a SunPass Portable with the rental's plate added to the account. Florida's Turnpike also warns of a $2.50 administrative charge on toll-by-plate invoices, which go to the registered owner and not the driver.

The Turnpike mainline toll at Homestead Plaza on the way to the Keys is $1.16 with SunPass and $1.45 by plate, effective 21 April 2026. A hire-car driver pays what the rental programme sets, not the plate figure. If you drive the northern legs, the I-95 Newark plaza in Delaware charges $5.00 a car, in cash or by E-ZPass.

We could not read the Massachusetts, New York, New Jersey and Maryland toll pages, which matter only if you drive the northern legs, so we print no figures for them. Ask the hire company about its toll programme before leaving the counter, and ask how it charges for each state. We found no official toll figure for Virginia either.

Which months suit one north-to-south drive?

April and May suit a single north-to-south drive best, with mid-October to mid-November second. That is our reading of NOAA's 1991 to 2020 normals, because no source ranks months. In April, hurricane season has not begun, Boston's high is 56°F and Miami's is 84°F.

January is the wrong month for the northern legs: Boston averages 14.3 inches of snow that month. We would avoid July and August. Miami has 23.8 days at 90°F or more in July and 24.7 in August. Its rain runs from 7.4 to 10.5 inches a month from June to September. October still has 7.7 inches of rain in Miami, and Shenandoah's lodges start closing on 8 November.

How dangerous is hurricane season for the Keys leg?

Hurricane season for the Keys leg runs from 1 June to 30 November, according to the National Hurricane Center, and its peak is 10 September. The Florida Keys tourism council puts the highest potential for storms between 15 August and 15 October. On 5 November 2026 the season was 25 days from its end.

The rule that matters to a visitor is the council's, not the county's, because we could not read Monroe County's own pages. In the council's words, visitors are asked to leave the Keys for a hurricane of any category. Residents must evacuate for Category 3 storms or higher. Visitors are asked to leave first, and the council says that because the Keys have only one highway, evacuations take longer. Each property has its own refund policy.

What is the Overseas Highway, and what is being built on it?

The Overseas Highway is the 113-mile road to Key West, with 42 bridges, which the Florida Keys council describes as Florida's only All-American Road. Its green mile markers run from 127 near Florida City to 0 in Key West. Our routing puts Florida City to Key West at about 127 miles, so 113 is the highway proper and not the distance from Miami.

The Florida Department of Transportation began rehabilitating the Seven Mile Bridge on 2 March 2026. The works run between mile markers 40 and 47, and completion is estimated for summer 2029. Travel lanes may be closed only in non-peak hours, which FDOT defines as 8 p.m. to 6 a.m., Monday to Thursday. A driver crossing in those hours may meet a closed lane. The Turnpike Extension and Card Sound Road are cashless, so the toll rules above apply there too. For stops, see our guide to Key West.

Is the Shenandoah detour worth adding between Washington, D.C. and Charleston?

The Shenandoah detour adds about 81.5 miles and about 3 hours 20 minutes to the Washington, D.C. to Charleston leg. That uses the figure of about three hours for the 105 miles of Skyline Drive, from our Shenandoah National Park guide. Our own routing's time on that road is too short to use, because it ignores the 35 mph limit. The park puts itself about 75 miles from Washington.

Shenandoah National Park charges $30 a car for seven days and does not accept cash, only cards. It is not on the 2026 list of 11 parks that charge visitors from abroad $100 each. On 5 November 2026 the park's hours page showed Skyland, Elkwallow Wayside and Lewis Mountain closing on 8 November. It showed Big Meadows Lodge closing on 29 November, and said the dates are subject to change. Skyline Drive can also close in bad weather.

Everglades National Park sits on the list. It charges $35 a car plus $100 for each person aged 16 or over from abroad. Two adults in one car pay $235. The park takes only digital passes or cards. Our guide to national park fees for international visitors explains the $250 annual pass.

Which clock does the East Coast road trip keep?

The East Coast road trip keeps Eastern time from Boston to Key West. The federal rule 49 CFR 71.4 defines the Eastern zone. In Florida the Central zone begins west of the Apalachicola River, which the route never reaches.

Daylight saving time ended on 1 November 2026 at 2 a.m. The next change is 14 March 2027, our arithmetic from the second-Sunday rule on NIST's page. No clock changes on the road in between.
