Acadia is one of the most rewarding national parks to see by RV, and one where two questions decide the trip before you ever pull in: how long is your rig, and did you win the reservation race? The size question is sharper here than most renters expect, and the booking window is unforgiving — once campsites open six months out at 10 a.m. EST, the good ones go in minutes. So this guide leads with the answers the top search results bury: what fits where, where the hookups are, and how to actually land a site.
The short version:
- Acadia has three RV-capable campgrounds: Blackwoods and Seawall on Mount Desert Island, Schoodic Woods on the quieter Schoodic Peninsula.
- Blackwoods fits the biggest rigs in the park, with RV sites up to 35 feet — but no hookups.
- Schoodic Woods is the only Acadia campground with hookups (electric at most sites, electric + water in B-Loop) — but its sites cap around 20–25 feet, and Schoodic Loop Road blocks anything over 21 feet past day-use.
- Reservation race is real: 90% of sites release exactly six months ahead at 10 a.m. EST on the 1st of the month; the other 10% drop on a 14-day rolling window. Set an alarm.
- Going for fall color? Acadia peaks the third week of October — book the moment the window opens, and check that your campground is still open that late.
Does Acadia National Park allow RV camping, and where?
Yes — Acadia has three RV-capable campgrounds: Blackwoods and Seawall on Mount Desert Island, and Schoodic Woods on the quieter Schoodic Peninsula. A fourth campground, Duck Harbor on Isle au Haut, is mailboat-access only and doesn't take RVs at all.
In our experience, renters fixate on Bar Harbor and miss Schoodic Woods entirely — yet Schoodic is the one Acadia campground with electric hookups, and the only one a renter who wants to plug in should look at first. The catch is size, which we'll get to in a minute. On the Mount Desert Island side, Blackwoods sits about five miles south of Bar Harbor, close to the Park Loop Road and Cadillac Mountain trailheads, while Seawall is roughly four miles south of Southwest Harbor on the quieter west side of the island. Schoodic Woods is on the mainland Schoodic Peninsula, about an hour and 15 minutes' drive from Bar Harbor — far enough that most renters skip it without realizing what they're skipping.
If you'd rather pick up an RV nearby instead of driving one across New England, Acadia National Park RV rentals and Ellsworth, the closest Acadia gateway for rentals are the practical starting points.
What's the max RV length at each Acadia campground — and which has hookups?
Blackwoods has the most generous size limits — RV sites cap at 35 feet, with no hookups. Seawall is similar: 35 feet max on RV-capable sites, no hookups. Schoodic Woods is the one with hookups (electric at most sites, electric + water in B-Loop), but its sites cap around 20–25 feet — and Schoodic Loop Road bans any vehicle over 21 feet past the day-use parking, which means the campground itself is small-rig territory.
Here's the trade-off in one table:
A renter watching that table for the first time tends to do a double take — the campground with hookups is also the campground with the tightest size cap. Renters we hear from who book a 40-foot rig for Blackwoods get a hard "no" at check-in, since recreation.gov enforces the per-site length you reserved. The size mistake we flag most for this park is renting something in the 30–35-foot range with the assumption that hookups are coming. They aren't, anywhere in the park, unless you're 25 feet or under at Schoodic.
The clean read: if you want to drive Acadia in a big rig (up to 35 ft), Blackwoods or Seawall are your only in-park options and you'll be dry-camping. If hookups matter more than space, rent a rig under 25 feet for Schoodic Woods. If you've got something over 35 feet, you're staying outside the park entirely — a private full-hookup park in or near Bar Harbor, like the Bar Harbor Oceanside KOA, is the play.
How do you actually get an Acadia campsite (the reservation race)?
Acadia releases 90% of campsites exactly six months ahead, on the 1st of each month at 10 a.m. EST, with the remaining 10% dropping on a 14-day rolling window at 10 a.m. EST. All bookings run through recreation.gov — there is no walk-up reservation, no in-person desk. To land an arrival date of October 20, you can book starting at 10 a.m. EST on April 1; if you miss that, you can try at 10 a.m. EST on October 6 from the second release.
We've watched the 10 a.m. EST release on the first of the month decide whether renters get an Acadia site at all — the ones who treat it like a ticket drop win, and the ones who log in at 10:05 wonder where everything went. The practical setup: have your recreation.gov account created and logged in days ahead, know your campground and your second-choice campground, have the dates in a tab ready to submit, and refresh at 10 a.m. EST sharp on the 1st. Most months, the desirable nights at Blackwoods and Schoodic Woods are gone in under an hour.
A few things worth knowing about the release mechanics:
- The 10% rolling release is your second chance, and it's not a fluke channel — campers do cancel inside the two-week window. Set a calendar reminder for 14 days before your arrival and try again.
- Same-day reservations are possible if a site is available — recreation.gov allows them, but supply is thin in July and August.
- Camping in Acadia is capped at 14 nights combined between Memorial Day Friday and Columbus Day, and 30 nights per calendar year — relevant if you're planning a long stay.
When does Acadia fall foliage peak, and how does that change your booking?
Acadia color peaks the third week of October, two to three weeks behind the western Maine mountains because the coastal microclimate runs cooler later. That third week is also when Blackwoods is wrapping up its season (2025 ran through Oct 20), Seawall has usually closed (2025 ran through Oct 13), and Schoodic Woods is typically already shut for the year. Your campground options narrow exactly when the color is best.
That makes the booking sequence simple: confirm your campground's 2026 closing date on the NPS Acadia camping page, pick a foliage-week arrival date that falls inside it, then mark the date six months prior on your calendar for the 10 a.m. EST release. For a third-week-of-October foliage trip, that's an April release date — and a peak-foliage Blackwoods stay tends to be gone the morning it opens.
A practical wrinkle for foliage trippers: nights in Acadia in mid-October regularly drop into the 30s°F. No-hookup means no electric heater, and Blackwoods and Seawall are no-hookup. Bring propane, batteries to run the furnace fan, and a heavy sleeping bag if you'll be there past mid-October.

Do you need a Cadillac Summit reservation, and what else should an RVer know?
Yes — driving Cadillac Summit Road requires a separate timed-entry vehicle reservation from May 20 through October 25, 2026, booked through recreation.gov. It's not the same as your campground reservation and doesn't come with it. Two ticket types are available: a sunrise reservation (one per vehicle every seven days) and a daytime reservation (one per vehicle per day). Reservations must be purchased in advance — they aren't sold at the park.
A few other things first-time RVers in Acadia tend to get wrong:
- No backcountry, "out-of-bounds," or overnight parking is allowed anywhere in the park. That includes pullouts, trailhead lots, and Walmart-style boondocking inside Acadia. Stay at a campground or a private park.
- Don't bring firewood from more than 50 miles away — Maine and Acadia regulate firewood to slow the spread of invasive insects. Buy it from a local vendor near the campground.
- Park Loop Road has historic stone bridges with low clearance. If your rig is over about 11 feet, check the NPS oversized vehicles page before driving the loop.
- Generator hours at Blackwoods are 8–10 a.m. and 4–7 p.m. in A-Loop only; B-Loop is generator-free. Plan power around that if you're dry-camping.
- The Island Explorer shuttle is free, wheelchair-accessible, and stops at the campgrounds, carriage road entrances, and major trailheads from late June to mid-October — leave the rig at camp and ride it.
If you'd rather not move your RV at all once you arrive, you can have a rig delivered to a base park at Schoodic or near Bar Harbor and ride the shuttle from there. Browse the wider region on the Maine RV rentals hub, or look at the Schoodic Woods Campground rental page if Schoodic is the goal.
Key takeaways
- Three campgrounds take RVs: Blackwoods and Seawall (Mount Desert Island), Schoodic Woods (Schoodic Peninsula). Duck Harbor doesn't.
- Blackwoods and Seawall fit up to 35 ft, no hookups. Schoodic Woods is the hookup campground — but caps at 20–25 ft per site, with a 21-ft limit on Schoodic Loop Road past day-use.
- Win the release: 90% of sites drop six months ahead at 10 a.m. EST on the 1st; 10% drop 14 days out. Treat it like a ticket sale.
- Foliage peaks the third week of October — book six months ahead, and check that your campground is still open that late.
- Cadillac Summit needs a separate timed-entry reservation, May 20 – Oct 25 2026. Sunrise and daytime tickets are different products on recreation.gov.
