The drive from Boston to Acadia National Park is about 280 miles and takes roughly 4 1/2 to 5 hours via I-95 North to Bangor, then ME-3 onto Mount Desert Island. Renting an RV in Boston means your transportation and your lodging are together in one cost. It also puts you just a few minutes from the park at Bar Harborβarea campgrounds. If you have an extra day, the coastal US-1 route through Portland and Camden trades speed for lighthouses and harbor towns. One catch every RVer should know before leaving: most RVs can’t drive up Cadillac Mountain, so plan to park the rig and explore by shuttle. Consult our Acadia National Park guide for the full park overview.

How Long is the Drive From Boston to Acadia National Park?
The distance from Boston to Acadia National Park is about 280 miles, or roughly 4 1/2 to 5 hours of driving without stops. In an RV, plan on 5 1/2 to 6 hours once you add fuel, food, and a leg stretch. Boston and Acadia are both on Eastern Time, so you don’t need to worry about a time change.
The slowest part of the trip is often the last few miles. Most drivers heading to Mount Desert Island have to funnel onto ME-3 and across the Trenton Bridge, and it backs up on summer afternoons.
When to leave Boston to beat summer traffic
On summer weekends, I-95 North through New Hampshire and southern Maine fills up fast with Friday-afternoon getaway traffic. Your best bet is to leave Boston early in the morning, ideally before 7 a.m., or travel midweek. Coming home, Sunday afternoons heading south are the slowest. Leaving Monday or early Sunday will make the drive much smoother.
What’s the Best Route From Boston to Acadia?
For most RV renters, the best route from Boston to Acadia is I-95 North to Bangor, then local highways to Mount Desert Island. It’s the fastest option and almost entirely interstate. If you’re willing to trade time for beautiful scenery, the coastal US-1 route is the classic Maine road trip.
I-95 North direct
Take I-95 North from Boston through Portsmouth, NH, then on to Portland, Augusta, and Bangor. From Bangor, follow I-395 and US-1A toward Ellsworth, then take ME-3 to the island. Wide lanes, easy inclines, and lots of truck stops make this the easiest drive for a first-time RV driver.
The coastal US-1 scenic route
Leave I-95 at Brunswick or pick up US-1 near Portland and follow the coast through Bath, Rockland, Camden, and Belfast to Ellsworth. You’ll pass lighthouses, lobster shacks, and working harbors. However, you’ll be on a two-lane road with lower speed limits, small town centers, and summer traffic, so it’s best for drivers with plenty of time.
Getting onto Mount Desert Island: fuel and propane before the bridge
Here’s a tip most travel guides miss: fill up in Ellsworth or Trenton before you cross onto the island. Top off your gas or diesel and your propane there. There are fewer fuel stations on Mount Desert Island, and they’re more expensive, and RV-friendly propane refills are hard to find once you’re on the island. Ellsworth is also your last easy stop for a big grocery run.
Best stops between Boston and Acadia
The best stops between Boston and Acadia are Portsmouth, Portland, Freeport, Camden, Ellsworth, and Bar Harbor. Each one makes a great place to stop and eat, fuel up, or spend the night.
Portsmouth, NH
About an hour north of Boston, Portsmouth is a historic port town. Streets near Market Square are tight for RVs, so park at the edge of town or use fuel stations off I-95.
Portland, ME
Portland’s Old Port district is known for its great restaurants and cobblestone streets. Skip driving an RV downtown; park outside the peninsula and walk or rideshare in. Portland is also yone of the big cities where you can shop at big-box grocery stores and stock up.
Freeport, ME
Freeport is the home of the L.L.Bean flagship store, which is open 24 hours. It’s right off I-95 and easy to reach in an RV. Look for the town’s designated RV and bus parking rather than trying to navigate parking spots on Main Street.
Camden, ME
On the US-1 route, Camden is a postcard harbor town with Camden Hills State Park just north of the village. The harbor area is narrow and busy in summer, so plan to park on the outskirts and walk in to town.
Ellsworth and Trenton, ME
This is your last practical service stop before Mount Desert Island. Fill up on fuel and propane, stock up on groceries, and empty your tanks if you can. Use RVshare’s dump station locator to find one nearby.
Bar Harbor, ME
Bar Harbor is the gateway town to Acadia, with shops, restaurants, and whale-watching tours. Downtown parking is hard for RVs, especially in summer. The easiest solution is to leave the rig at your campground and ride the free Island Explorer shuttle into town.
Where can you park and camp an RV near Acadia?
You can camp an RV inside Acadia at Blackwoods, Seawall, or Schoodic Woods, or at private RV parks around Bar Harbor and Mount Desert Island. The big difference is hookups: the two RV-friendly campgrounds on the island have none, while Schoodic Woods and most private parks do.
Campgrounds inside the park
Blackwoods is about 5 miles south of Bar Harbor, close to the Park Loop Road. Seawall is on the quieter west side of the island near Southwest Harbor. Both charge $30 a night for RV sites, and neither has water, electric, sewer, or showers. Plan to stock up on water and charge your batteries before arriving, and check each site’s length on Recreation.gov before you book.
Schoodic Woods is on the mainland Schoodic Peninsula, about 1 hour 15 minutes from Bar Harbor. It’s the only campground in the park with hookups. Electric-only RV sites run $36 a night, and electric plus water sites run $40. All three campgrounds book only through Recreation.gov, with most sites released six months ahead.
Bar Harbor and Mount Desert Island private RV parks
If you need full hookups, consider private RV parks in Bar Harbor, Trenton, and around the island. You’ll likely find higher nightly rates than the park campgrounds, but you’ll get extras like showers, laundry, and Wi-Fi. July and August sell out early, so book as soon as you know your plans.
Can you drive an RV up Cadillac Mountain?
You usually can’t drive an RV up Cadillac Mountain. Cadillac Summit Road has a 21-foot vehicle length limit, so most motorhomes and any vehicle towing a trailer can’t make the drive. Even smaller vehicles need a timed vehicle reservation from May 20 through October 25, 2026. Reservations cost $6 per vehicle at Recreation.gov in addition to your park entrance pass, and you can’t buy them at the park.
The best plan is to park the rig at your campground and ride the free Island Explorer shuttle. Full service runs from late June to mid-October and stops at campgrounds, Sand Beach, Jordan Pond, and Bar Harbor. However, the Island Explorer doesn’t go up Cadillac Summit Road. To reach the top, drive a tow vehicle or car under 21 feet with a reservation, or hike or bike up. Hikers and cyclists don’t need a reservation.
Best RV options for a Boston-to-Acadia trip
A Class C motorhome is the best pick for most first-time renters taking a road trip from Boston to Acadia National Park. Class Cs are easy to drive on I-95, fit most campground loops on Mount Desert Island, and don’t require a tow vehicle.
Class C motorhomes handle interstate driving well and park more easily than larger rigs. They’re a great option for couples and small families staying at Blackwoods or Seawall.
Travel trailers give you the most flexibility once you arrive. Set up camp, unhitch, and use your tow vehicle to explore. If your tow vehicle is under 21 feet, it can also make the drive up Cadillac Mountain if you have a timed reservation.
Class A motorhomes offer the most space and comfort, but length can be a challenge. Confirm the site length before you book a campground, and plan to keep your rig parked and ride the shuttle once you arrive.
Cost breakdown: Boston to Acadia by RV
An RV rental can cost the same as or less than a trip where you fly into Bar Harbor during peak season. This is especially true for families because an RV is both your transportation and lodging. Hereβs what to budget.

For comparison, flying into Bangor or Portland means adding airfare, a rental car, and a Bar Harbor hotel, which often runs $250β400 or more per night in July and August. Note that starting in 2026, non-U.S. residents age 16 and older pay an extra $100 per person to enter Acadia unless they hold an annual pass.
