The four campgrounds inside the park
Acadia runs four campgrounds and nothing else. No backcountry camping, no dispersed camping, no permit for a night on a summit. If you want to sleep on park land, it is Blackwoods, Seawall, Schoodic Woods or Duck Harbor. All four are booked through recreation.gov, and none hold sites for walk-ups. The park carries a 4.9 rating from more than 24,000 Google reviews; demand for the campgrounds inside it outruns supply most of the summer.
Blackwoods
About five miles south of Bar Harbor on Route 3, Blackwoods is the default and the one most people picture: spruce and birch overhead, soft duff underfoot, sites set far enough apart that you are not staring into someone else's vestibule. It sits within reach of the Park Loop Road, so Sand Beach (4.8 from around 970 reviews) and Thunder Hole (4.6 from over 3,200) are a short drive or a bus ride away. A footpath drops toward the shore. A walk rather than a scramble, though what you reach is cobble and ledge, not sand.
Some sites take RVs, some are tent-only, and maximum vehicle lengths vary site by site. Read that detail on the recreation.gov page before you book a 30-footer into a loop that cannot take one. Blackwoods usually holds the longest season of the four; current dates are on nps.gov.
Seawall
Seawall is on the quiet side of Mount Desert Island, on Route 102A a few miles past Southwest Harbor, and it rates 4.8 from 86 reviews. The pitch is straightforward: fewer people, more fog, and open ocean across the road at the Seawall picnic area, where the surf works over a berm of granite cobbles all night. It is the best of the four for tent campers, partly because a share of the sites are walk-ins: a short carry from the parking area, which filters out most of the RV traffic and much of the noise.
The walking nearby is excellent and undemanding. Ship Harbor Trail (4.8 from 115 reviews) is two minutes up the road, Bass Harbor Head Light Station (4.4 from over 4,600 reviews) is the sunset stop everyone makes, and Echo Lake Beach (4.7 from 193 reviews) is the freshwater swim for when the Atlantic proves too cold, which it will.
Schoodic Woods
Schoodic Woods is not on the island at all. It sits on the mainland Schoodic Peninsula near Winter Harbor, about an hour from Bar Harbor around the head of Frenchman Bay. It is the newest of the four and it shows: wide graded sites, a proper contact station, and the only utility hookups anywhere in Acadia, with a portion of sites carrying electric and water. If you are traveling in a large RV, aim here.
It connects straight into a network of gravel bike paths and the Schoodic Loop Road, so you can ride to the headland without touching the car, and the Schoodic Institute (4.7 from 41 reviews) runs public programming a few minutes away. The trade-off is distance: you are not popping over to Jordan Pond for a spare afternoon. Treat Schoodic as its own base, and check nps.gov for the season. This campground's operating dates have shifted between years.
Duck Harbor, Isle au Haut
Duck Harbor is the outlier and the prize. Five lean-to shelters sit on the Acadia-managed end of Isle au Haut, reached by mailboat from Stonington. Itself roughly two hours' drive from Bar Harbor. No car, no store, no bailing out early if the weather turns. The season is short, the stay limit is tight, and the water supply is limited enough that you should confirm its status on nps.gov rather than assume it. The entire season releases on a single date in spring and goes quickly.
How the booking window actually works
Blackwoods, Seawall and Schoodic Woods open on a rolling window: a new day's inventory becomes bookable a fixed number of months ahead, at a set hour, every day. Duck Harbor is different: one release date, one shot at the season. Recreation.gov publishes the window and release time for each campground, and it does change, so read the campground page rather than an old forum post.
For a July or August weekend, be logged in and holding your dates before the release hour. Weekday nights and late September are far easier. If you miss out, keep checking. Cancellations shake loose steadily in the four weeks before a date, and Seawall's walk-in sites reappear more often than you would expect.
Two things a reservation does not include: the park entrance pass, and the vehicle reservation for the Cadillac Summit Road, which is required in season and booked separately on recreation.gov. Sunrise slots go quickly, and a Blackwoods site gives you no claim on one. Current fees are listed on nps.gov.
Which campground suits which visitor
- First visit: Blackwoods. Closest to the Park Loop Road, Sand Beach and the eastern trailheads, and the easiest base for a three-day highlights trip.
- Tent campers who want quiet: Seawall, specifically a walk-in site. Ocean across the road, less traffic, a village nearby for coffee.
- Big RV or anyone needing hookups: Schoodic Woods, the only Acadia campground with electric and water sites.
- Cyclists: Schoodic Woods for gravel paths off the doorstep, or Blackwoods for shuttle access to the carriage roads.
- Backpackers wanting solitude: Duck Harbor, if you can win the release date.
What the sites are like
Expect a cleared pad, a picnic table and a fire ring. Restrooms have flush toilets and cold running water. None of the park campgrounds have showers: campers use private coin-operated showers nearby, and the park signposts the closest options. Quiet hours run overnight and are enforced, and generator use is restricted to posted windows.
Store food in a hard-sided vehicle or a locking container. Black bears are uncommon on Mount Desert Island, but raccoons are relentless and gulls will open a cooler lid left propped. Buy firewood locally, Maine restricts the movement of out-of-state firewood to slow the spread of forest pests. Dogs are welcome on a short leash in the campgrounds and on most trails, unusual for a national park and one of Acadia's real advantages.
Getting around without the car
The Island Explorer shuttle is the biggest single reason to camp in the park rather than outside it. The buses are fare-free, run a summer-into-autumn season, and hub at the Village Green in Bar Harbor (4.6 from over 1,100 reviews). The Blackwoods route links that campground to town, the Southwest Harbor route stops at Seawall, and a separate route serves the Schoodic Peninsula.
The point is not saving fuel. Trailhead lots at Sand Beach, the Beehive and the Jordan Pond Path Trailhead (4.8 from around 570 reviews) fill by mid-morning in August, and a bus skips that problem entirely, including the trick of riding out and walking back one way. Our guide to the best hikes in Acadia flags which trails suit that.
Food and resupply
Ellsworth is the last full-size supply town on the way in, and the sensible place for a real grocery run, propane and anything you forgot. Once you are on the island, prices climb and choice narrows.
For nights you do not want to cook: Bar Harbor's Side Street Cafe (4.4 from over 4,600 reviews) handles a hungry, sandy family without complaint, and The Travelin Lobster (4.8 from around 1,900 reviews) is a roadside stop on Route 102. Seawall campers have Beal's Lobster Pier (4.5 from over 1,100 reviews) in Southwest Harbor (a working wharf with picnic tables rather than a restaurant) and Trenton Bridge Lobster Pound (4.4 from around 1,700 reviews) sits by the causeway on the drive in. For a rained-out afternoon, our roundup of things to do in Bar Harbor covers the indoor options.
In-park versus private campgrounds
These are different products. The Route 3 corridor between Ellsworth, Trenton and Bar Harbor holds a cluster of private campgrounds with full hookups, pools, laundry, wifi and cabins, several on an Island Explorer stop. If you need 50-amp service, a shower block or a site next week in August, private is the realistic answer. What you give up is the setting: park campgrounds are quieter, darker and more wooded, and they put you inside the boundary, which matters most at dawn and dusk. There is a middle option too: Lamoine State Park (4.6 from nearly 500 reviews) camps on Frenchman Bay looking across to the mountains, and books through Maine's state park system rather than recreation.gov, a separate queue entirely.
When to go
Black flies peak in late May and June and can ruin an evening on the quiet side. July and August bring the crowds, the warmest water and reliable morning fog at Seawall. September is the best month by a wide margin: settled weather, thinner traffic, easier reservations, and water still warm enough for Echo Lake. Early October adds foliage and removes most of the shuttle service and the Duck Harbor season. Pack for nights in the 40s and 50s Fahrenheit whatever the month, and bring a tarp.
Frequently asked questions
How far in advance should you book camping in Acadia National Park?
Blackwoods, Seawall and Schoodic Woods release sites on a rolling window several months ahead, and July and August weekends typically go within minutes of that release, so book the moment your dates open on recreation.gov. Duck Harbor on Isle au Haut works differently: the whole season opens on one date in spring. Shoulder-season weekdays are the exception and can often be picked up a week or two out.
Are there showers at Acadia National Park campgrounds?
No. None of the four park campgrounds have shower facilities; restrooms provide flush toilets and cold running water only. Campers use privately run coin-operated showers close to Blackwoods and Seawall, and the park posts the nearest options at each campground. If an on-site shower matters to you, a private campground on the Route 3 corridor is the better fit.
Can you camp anywhere in Acadia National Park?
No. Backcountry and dispersed camping are prohibited throughout Acadia, including roadside pull-offs, summits and the carriage roads. Overnight camping is legal only at Blackwoods, Seawall, Schoodic Woods and the Duck Harbor shelters on Isle au Haut, all reserved through recreation.gov. Sleeping in a vehicle outside a reserved site is not permitted.
Which Acadia campground is best for RVs?
Schoodic Woods, on the mainland Schoodic Peninsula. It is the only campground in the park with electric and water hookups, its sites are graded and generously sized, and its internal roads handle larger rigs comfortably. Blackwoods and Seawall accept RVs but have no hookups and impose site-specific length limits, which are listed on each site's recreation.gov page.
