Blackwoods vs. Seawall vs. Schoodic Woods: Which Acadia campground fits your RV?

Quick answer: Pick Blackwoods when Mount Desert Island sightseeing and shorter drives to Bar Harbor matter most. Pick Seawall for the quieter west side, but only after confirming that your RV and tow vehicle can handle its tight, dry-camping layout. Pick Schoodic Woods when electric service matters or you have a larger rig that fits a specific reservable site. The tradeoff is distance: Schoodic Woods is on the mainland peninsula, not beside Acadia's main Mount Desert Island sights.

Acadia's 2026 operating schedule lists Blackwoods from May 1 through October 19 at 10 a.m. Seawall and Schoodic Woods are listed from May 20 through October 12 at 10 a.m.^[1] Those dates put all three within their scheduled season on September 10, 2026. Weather, emergency work, and other conditions can still change access, so check the park's current-conditions page before moving the rig.^[9]

The comparison at a glance

The comparison uses the 2026 NPS season table and the three current Recreation.gov facility records.^[1][2][3] Schoodic's two long-rig examples come from the individual B01 and B10 listings.^[7][8] The park compendium and oversized-vehicle page control the campground-wide generator, size, and road restrictions.^[5][6]

Blackwoods: the location-first choice

Blackwoods sits about six miles south of Bar Harbor, with its entrance directly off State Highway 3. Recreation.gov warns that there is no campground entrance from Park Loop Road.^[2] That detail matters more in an RV than it does in a car. Arrive by the signed Route 3 approach instead of letting a navigation app improvise through the park.

This is dry camping. Blackwoods has drinking water, flush toilets, and a dump station, but the campsite list is nonelectric.^[2] If batteries or a medical device require generator time, reserve in A Loop. The approved windows are 8-10 a.m. and 4-7 p.m.; B Loop is generator-free, and the camper must remain at the site while the generator runs.^[2][5]

Rig fit needs two checks. First, the park compendium caps RVs at Blackwoods at 35 feet in length and 11 feet in height, with slide-outs contained on the pad.^[5] Second, the reserved site's equipment limit can be lower. Recreation.gov displays 20-foot and 35-foot RV sites and warns that a reservation may be canceled when equipment exceeds the site's listing.^[2] A nominally 35-foot motorhome therefore needs a 35-foot-compatible site; the campground-wide ceiling does not make every pad suitable.

Blackwoods is the practical pick for travelers who want their tow car or toad close to Bar Harbor and the east-side park circuit. It is a poor match for campers who need an electrical pedestal or expect to tour Park Loop Road in a tall motorhome. NPS lists RV and trailer prohibitions at several popular parking areas, and its oversized-vehicle page says the shortest Park Loop Road underpass is 11 feet 8 inches.^[6]

Seawall: the quiet-side choice, with the hardest fit test

Seawall is on Mount Desert Island's west side, south of Southwest Harbor. That shifts the daily trip pattern toward Bass Harbor, Echo Lake, and west-side trails rather than Bar Harbor and the east-side highlights. It is still an Acadia base, but it is not interchangeable with Blackwoods.

The service setup resembles Blackwoods: no campsite hookups, but shared running water, flush toilets, and a dump station. There are no campground showers.^[3] Generator users have only one workable loop. C Loop permits operation from 8-10 a.m. and 4-7 p.m.; Loops A, B, D, and G prohibit generators.^[3][5]

The fit warning is stronger here. Recreation.gov says only some sites accept RVs up to 35 feet, calls maneuvering difficult, and says the campground was not designed for large RVs and trailers. It also states that staff cannot accommodate an RV that does not fit its reserved site.^[3] The compendium adds the same 35-foot length and 11-foot height ceiling used at Blackwoods.^[5]

Measure the camping unit, then read the exact site's driveway and equipment fields. For a trailer, do not assume a "35-foot site" solves the combined parking problem. Confirm where the tow vehicle goes, whether the trailer itself fits, and whether slides remain over the pad. Seawall makes sense when location wins and the rig is comfortably inside the listing, not when every inch has to work perfectly.

One current Recreation.gov direction note says a detour is in place.^[3] Because detours can change, use the live reservation page and NPS conditions shortly before arrival rather than saving a summer route months in advance.

Schoodic Woods: the utility-first choice

Schoodic Woods is the outlier in this comparison. It is on the Schoodic Peninsula near Winter Harbor. Recreation.gov puts the drive to Bar Harbor, near Acadia's primary Mount Desert Island district, at roughly 60-70 minutes. It also says there is no Island Explorer shuttle between Schoodic Peninsula and Mount Desert Island.^[4] Booking it for an east-side itinerary can turn each sightseeing day into a long transfer.

For RV systems, however, Schoodic Woods has the strongest setup. Drive-up sites have electric service; B Loop sites add water hookups. The listed electrical options include 20-, 30-, and 50-amp service, depending on site, and the campground also has potable water, flush toilets, and a dump station.^[4] Generators are prohibited, so the pedestal is not a bonus for generator-dependent campers; it is the alternative.^[5]

Schoodic's rig capacity is site-specific rather than one simple maximum. Recreation.gov currently lists B01 with a 47-foot maximum vehicle length and B10 with a 60-foot maximum, both as pull-through RV sites with water and 20/30/50-amp service.^[7][8] Those examples prove that Schoodic can fit rigs beyond the 35-foot Blackwoods and Seawall ceiling. They do not prove that another site fits the same RV. Smaller A Loop listings can be much tighter, so the exact equipment and driveway record remains the controlling check.^[4]

Do not confuse campsite fit with touring access. Recreation.gov says vehicles, RVs, and trailers longer than 21 feet must stop before continuing past the campground and day-use complex on Schoodic Loop Road; oversize parking is available there.^[4] The NPS oversized-vehicle page separately closes the portion beyond the Schoodic Woods day-use area to RVs and trailers.^[6] Set up camp, then use a compliant smaller vehicle, bicycle, or in-season peninsula shuttle for the loop.

Reservations: one release system, no walk-up counter

All three campgrounds use Recreation.gov. For each one, 90 percent of sites become available six months ahead in a monthly release at 10 a.m. Eastern on day one of the month. The remaining 10 percent open on a rolling basis at 10 a.m. Eastern, 14 days before the desired arrival date.^[2][3][4] Same-day booking is possible only when inventory remains, and campground offices do not make reservations in person.^[2][3][4]

That monthly release is not the same as a day-by-day six-month window. A July stay, for example, belongs to the January 1 monthly release for the 90-percent block. The late block follows the arrival date itself. Check the time zone shown by Recreation.gov at booking, especially around seasonal clock changes.

Late arrival does not mean losing the site that evening. The campground pages direct after-hours arrivals to the reserved site. Blackwoods' NPS guidance says to report to the ranger station no later than 10 a.m. the next day, and the Seawall and Schoodic pages carry the same next-morning instruction.^[2][3][4] Recreation.gov's no-show language says a reservation may be canceled if the camper has not arrived by 10 a.m. the day after scheduled arrival, with a service fee and first-night forfeiture.^[2][3][4]

A four-step RV booking check

1. Choose the park district first. Use Blackwoods for east-side Mount Desert Island access, Seawall for the west side, or Schoodic Woods for the mainland peninsula. Do not book Schoodic as though it were a Bar Harbor campground.
2. Eliminate by power need. Schoodic has electric sites, and the park prohibits generators there.^[4][5] Blackwoods and Seawall are dry, with generators allowed only in one designated loop and only during two daily windows.^[2][3]
3. Measure the complete setup. Record motorhome or trailer length, tow-vehicle parking needs, height, width with slides, and whether you need pull-through access. Then compare those numbers with the individual Recreation.gov site, not just the campground overview.
4. Build an RV-safe arrival and touring plan. Route Blackwoods from Route 3 and recheck Seawall's live detour note.^[2][3] Plan to leave oversize vehicles at Schoodic Woods before exploring the restricted loop.^[4][6]

Bottom line

Blackwoods wins on access to Acadia's busiest Mount Desert Island sights. Seawall wins for the west side, provided the rig fits without wishful measuring. Schoodic Woods wins on RV utilities and offers individual sites that can accept longer vehicles, but it changes the geography of the trip and bans generator use.

The safest booking choice is the one that survives three tests at once: exact-site fit, power strategy, and the roads you intend to drive after camp is set. A campground name alone cannot answer all three.
