Morning in Acadia begins at the sea. Salt air moves through the pine forest, and the sound of waves striking the granite shore carries softly to the campground. But to enjoy this landscape by RV, travelers first need to understand the character of its three campgrounds. Even within the same park, Blackwoods, Seawall, and Schoodic Woods differ clearly in hookups, access, and atmosphere. Rather than choosing only by the open sites on a reservation screen, first decide where you want to center the trip.
Stay near the heart of the island, or head for a quiet peninsula?
Blackwoods Campground, on the east side of Mount Desert Island, is a convenient base camp near popular attractions. The shore is about a 10-minute walk from its forested sites, and it offers easy access toward Park Loop Road and Bar Harbor. According to the NPS API, non-electric RV sites cost $30 per night, with seasonal access to drinking water, flush toilets, and a dump station. There are no showers in the campground, and cell service is unreliable.
Seawall Campground on the west side is close to the ocean, as its name suggests, but has a slower-paced atmosphere. It suits travelers planning to combine Southwest Harbor, Echo Lake, and relatively quiet trails. Non-electric RV sites cost $30 per night, and drinking water, flush toilets, and a dump station operate seasonally. However, turning space inside the campground is tight, and back-in sites can be difficult to enter. The NPS and RIDB state that larger RVs may be denied entry if they do not fit the reserved pad. Be sure to compare your rig’s length with each site’s permitted dimensions.
Schoodic Woods Campground appeals to RV travelers looking to escape the crowds on the main island. Electric-only sites cost $36 per night, while RV sites with both electric and water cost $40 per night. A seasonal dump station and drinking water are also available. The campground is on the Schoodic Peninsula near Winter Harbor, a little more than an hour’s drive from Bar Harbor. That can be inconvenient for an itinerary that visits main-island attractions every day, but it is an advantage for a slower trip focused on the rocky shore and bike paths.
Actual site dimensions matter more than the 35-foot number
Although the general RV limit at Blackwoods and Seawall is often listed as 35 feet, that does not mean every site can accommodate a 35-foot rig. At Seawall in particular, permitted lengths are shorter in some loops and at some sites. Check the reservation page’s Equipment Allowed listing, the shape of the access drive, and the pad length. If you are towing a trailer, consider not only the trailer length but also where the tow vehicle will go. It also matters whether slide-outs extend into the road and whether the setup fits within the tree and rock boundaries.
The park’s roads still include historic low bridges and narrow sections. It is safer and more comfortable to leave the RV at the campground and use a passenger vehicle or shuttle than to plan on taking the RV to every scenic stop. The free Island Explorer connects several key destinations during summer. Simply avoiding the time spent searching for space with a large rig in crowded trailhead parking lots can make a meaningful difference in the trip.
Reservations open twice: six months ahead and 14 days ahead
Reservations for Blackwoods, Seawall, and Schoodic Woods are accepted only through Recreation.gov. They cannot be made at the campground office or on-site. Ninety percent of sites are released at 10 a.m. Eastern Time on the first day of each month, six months in advance; the remaining 10 percent are released on a rolling basis at 10 a.m. Eastern Time, 14 days before the desired arrival date. If you miss the first opportunity, it is worth adding the second release time to your itinerary rather than giving up on the trip. Even if same-day sites remain available, the online reservation must be completed first.
For 2026, Blackwoods is scheduled to operate from May 1 through 10 a.m. on October 19, while Seawall and Schoodic Woods are scheduled to operate from May 20 through 10 a.m. on October 12. Services may be reduced late in the season, so check NPS operating information and Recreation.gov reservation details again just before arrival.
Travel style comes before hookups
If electricity is essential and you want to minimize trips to refill water, Schoodic Woods is the simplest choice. If access to Bar Harbor and Park Loop Road takes priority, Blackwoods has the advantage. Seawall is a good fit if you can manage batteries and water for several days without a generator and prefer the quiet western shore. None of the three campgrounds has showers. Portable outdoor showers are also prohibited, so plan for paid showers elsewhere.
Generator rules also vary. At Blackwoods, generators are allowed in Loop A from 8 to 10 a.m. and from 4 to 7 p.m., but are prohibited in Loop B. At Seawall, they are allowed only in Loop C during those same hours and cannot be used in Loops A, B, or D. Generators are prohibited at Schoodic Woods. Reserving a generator-permitted area while expecting a quiet forest can create discomfort for everyone, so account for your noise preference when booking.
Park the RV and take the coast slowly
In Acadia, reducing travel between stops can make the scenery more memorable than trying to check off as many sights as possible in a day. From Blackwoods, use the shuttle to link Ocean Path and coastal overlooks. At Seawall, group Echo Lake and the communities on the southwest side of the island into one outing. At Schoodic Woods, leave a day open for the peninsula’s one-way loop and bike paths. RVs are restricted on Schoodic Loop Road except for the campground access section, so large rigs should remain at the site.
During the summer high season, parking areas fill early, and the NPS advises that congestion is especially heavy from June through September. Instead of pursuing only sunrise, consider adding the late-afternoon coast, moonrise, and quiet evenings in the forest to the itinerary. Having a home on wheels is less about covering more miles than about staying longer in a good place.
A final check before departure
Review your reserved site’s permitted equipment length and entry direction, and pack a drinking-water hose and power adapter suited to your Schoodic Woods reservation type. At Blackwoods and Seawall, calculate battery charge, propane, and fresh-water use. All three campgrounds operate seasonally, so dump station and drinking-water availability can change. NPS alerts list a water-contact advisory at Sand Beach Lagoon and some trail closures to protect peregrine nesting habitat, so check the Conditions page just before your visit.
The key to RV camping in Acadia is not simply securing a well-known campground. It is deciding whether you want the pace of the main island or the quiet of the peninsula, then matching your rig’s true dimensions and power-use habits to that choice. With that preparation complete, a pine forest scented with the sea becomes a spacious living room, regardless of the size of your RV.
