New England: a 10-day to 2-week itinerary

New England is explored as a loop, by car, in 10 days from Boston or in 12 to 14 days from New York. The route strings together four highlights: the mansions of Newport, Boston, the Maine coast with Acadia National Park, then the White Mountains of New Hampshire. Two things need sorting out before you leave: the date, if you are aiming for the autumn colors, and the reservation for the Cadillac Mountain road in Acadia.

What to see in New England: the four stops on the route

Stop	Recommended nights	What to see	Good to know
Newport	1	The Breakers, Marble House, Rosecliff, the Cliff Walk (3.5 miles / 5.6 km)	One hour per mansion, very limited parking
Boston	3	Freedom Trail (2.5 miles / 4 km, sixteen sites), USS Constitution, Beacon Hill, Museum of Fine Arts	Ship closed Monday and Tuesday, museum closed on Tuesday
Maine coast and Acadia	2 to 3	Park Loop Road (27 miles / 43 km), Jordan Pond, Cadillac Mountain, Bar Harbor	Vehicle reservation for Cadillac
White Mountains	2 to 3	Mount Washington, Franconia Notch	Very changeable weather, dawn starts

Boston’s weekly closures decide the order of your days: place the Freedom Trail and the USS Constitution between Wednesday and Sunday, and the Museum of Fine Arts on a day other than Tuesday.

New England road trip: the route day by day

Here is a 12-day proposal starting from New York. This breakdown is a suggestion: Étaperia does not sell a tour of this length. Our travel guide New England and the Great Lakes covers 17 days and goes all the way to Niagara Falls.

• Day 1: New York, New Haven and the Yale campus (about 2 hours by road), then Newport (1 hour 30 minutes).
• Day 2: the Gilded Age mansions and the Cliff Walk in the morning, then about 1 hour 20 minutes by road to the edge of Boston.
• Days 3 and 4: Boston on foot and by metro. The Freedom Trail and the harbor one day, Beacon Hill, the Public Garden and the museums the next.
• Day 5: the Maine coast. About 5 hours by road to Mount Desert Island, with a break in Portland or Camden.
• Day 6: Acadia’s Park Loop Road, from Sand Beach to Jordan Pond.
• Day 7: sunrise on Cadillac Mountain, then Bar Harbor and its sand bar uncovered at low tide.
• Day 8: across Maine to the White Mountains, about 5 hours.
• Day 9: Mount Washington, the highest summit in the Northeast (1,917 m), on foot or by its toll road.
• Day 10: Franconia Notch, along the ridge for walkers or via Flume Gorge and Echo Lake.
• Days 11 and 12: back to Boston and flight.

In 10 days from Boston, drop the first two days and only pick up the car when you leave the city: parking there is expensive and scarce. In two weeks, add a day in Boston for the harbor islands (ferry from May to October) and a day in Acadia. For a route further south, see instead the East Coast in 2 weeks.

Watch out: The two 5-hour driving days quickly get longer on Fridays and in summer. Fill up before Ellsworth, the last large town before Acadia National Park.

Indian summer in New England: which dates to aim for

What many Europeans call the Indian summer is the fall colors. For American weather forecasters, the term means something else: an abnormally warm and dry spell, in October or November, after the first frosts. So it is the foliage dates you need to look at.

The colors move down from north to south and from the mountains to the sea:

• White Mountains: from late September to the second week of October, according to the regional tourist board. The colors hold for another week or two after the peak.
• Northern Maine: last week of September and first week of October, according to the state forest service.
• Central Maine and the western mountains: around the Indigenous Peoples’ Day weekend, in October.
• Coast and southern Maine: from mid-October to the end of the month. The state places Bar Harbor in its eastern zone, with no date of its own: for Acadia, rely on the weekly report.

The consequence is practical: in October, do the loop in reverse. The White Mountains first, in the opening days of the month, then the Maine coast around mid-October. It is the finest window on the route, and the most sought-after. Outside autumn, the season runs from late May to early October, as we explain in when to go to the United States.

Tip: The State of Maine publishes a foliage report every week, from mid-September to mid-October. Check it before fixing the order of your stops: the peak varies from one year to the next.

Acadia National Park: 2026 fees and booking the Cadillac Summit Road

Acadia is on the list of national parks that apply a surcharge to non-resident visitors. At the time of writing, in October 2026, the National Park Service website shows:

Item	Fee
Entry per vehicle, valid for 7 days	$35
Entry per person without a car, 7 days	$20, free up to age 15
Non-resident surcharge, aged 16 and over	$100 per person
Non-resident America the Beautiful annual pass	$250
Cadillac Summit Road reservation	$6 per vehicle
Island Explorer bus	Free

The non-resident annual pass covers entry and the surcharge for everyone in the vehicle. For two adults, single entry comes to $235 ($35 and two surcharges), that is $15 less than the pass. The pass becomes worthwhile from three adults ($335 without it), or as soon as you visit a second fee-charging park. Check these amounts again on nps.gov before you leave.

Driving up Cadillac Mountain also requires a reservation. In 2026, it was compulsory from May 20 to October 25: that season is over, and the 2027 dates will need checking on the park’s website.

• It is bought online only, on Recreation.gov. Nothing is sold at the park.
• 30% of places open 90 days before the date, 70% two days before, at 10:00 Eastern Time. They go within minutes.
• Two types of slot: sunrise (in October, entry between 5:30 and 7:00, then between 6:00 and 7:30 after the 15th) or daytime.
• Only one sunrise per vehicle per seven-day period: plan a fallback daytime date.

Car, tolls and budget on the ground

A car is essential between the stops. Two points to anticipate, on top of what we explain in renting a car in the United States:

• Tolls: many highways in the East have electronic tolling with no booths. The rental company’s transponder option avoids administration fees each time you pass through.
• Acadia: the free Island Explorer bus links Bar Harbor to the trailheads, but it does not go up Cadillac and the entrance pass is still required on board.

For meals, allow $15 to $25 at lunchtime and $25 to $45 in the evening excluding drinks, plus an 18 to 20% tip in restaurants. On Mount Washington, driving up the Auto Road in your own car is listed by its operator at $36 per adult and $15 for ages 4 to 12, a price noted in October 2026. The road only opens in season: in 2026, from April 25 to November 1, weather permitting. The summit can freeze even in August: check the Mount Washington Observatory forecast that very morning. As for entry formalities, they depend on your passport: our article on the ESTA covers that travel authorization, which is sorted out before departure.

So, which itinerary in New England?

• You have 10 days: arrive in Boston, three nights in the city, then Acadia and the White Mountains.
• You have 12 to 14 days: start from New York and add New Haven, Newport and a spare day in Acadia.
• You are aiming for the autumn colors: first half of October, mountains first, coast second.
• In every case: book Cadillac Mountain 90 days ahead, or two days ahead at 10:00 sharp.

If you have more time, our New England and Great Lakes itinerary extends the loop as far as Niagara, day by day. The other regions are on the United States page.
