RV Campgrounds in Maine: Hookups, Sites, Honest Reviews

Phone rang last week, feller from Ohio wanting to know where to plug in a 34-foot Class A near Bar Harbor without paying through the nose or staring at his neighbor's slide-out. I told him what I'll tell you: Maine is good country for an RV, but the state has its quirks. Short season, narrow roads, and a coast where everybody and their brother wants to be in July. You can do it right or you can do it dumb.

I spent close to four decades on the federal payroll, mostly out West, but my sister married a lobsterman out of Stonington back in '88 and I've been hauling a trailer up to Maine pretty near every other summer since. Sadie rides shotgun. What follows is the campgrounds I actually know — the ones I'd send my own family to, and the ones I wouldn't.

Around Acadia: Where The Hookups Actually Are

Here's the thing most folks dont realize about Acadia National Park itself: the park campgrounds — Blackwoods, Seawall, Schoodic Woods — do take RVs up to a point, but full hookup it ain't. Schoodic Woods on the mainland side has electric and water at some sites and a dump station, which is closer to "real" RV camping than the other two. Blackwoods and Seawall on Mount Desert Island are more tent-and-pop-up country, no hookups to speak of. Worth knowing before you tow a fifth-wheel down there expecting to plug in. Reservations go through Recreation.gov and the window opens months ahead — check it before you go, the rules shift.

For honest-to-goodness full hookup near Acadia, the private parks do the heavy lifting. Mount Desert Narrows in Bar Harbor and Hadley's Point Campground up the road in the same town are the two big ones. Narrows is on the water, which is right neighborly, but it's a big operation and it knows it. Hadley's is a bit more low-key, family-run feel last I checked. Smuggler's Den in Southwest Harbor is on the quiet side of the island and I've always liked it better for that reason alone — less traffic, easier to get in and out.

And one more — Mount Desert Campground in Somesville is a beautiful spot on Somes Sound but they're tent-leaning, small rigs only, no big-rig hookups. I mention it because every year somebody shows up with a 38-footer and gets turned around. Don't be that fella.

Inland: Moosehead, Sebago, and the Lakes Region

You want to get away from the coast crowds, go inland. Lily Bay State Park on Moosehead Lake up near Greenville has RV-capable sites, electric at some loops, and the kind of dark sky you forget exists. No full hookups but a dump station on site. The road in is fine for a normal rig, just take your time on the last stretch. Moose are common at dawn — and I mean common, not a brochure promise.

South of there, Sebago Lake State Park near Casco is the workhorse for southern Maine RV camping. Big lake, sandy beach, electric sites in the Witch Cove loop. Books up fast — and I do mean fast, the Mainers know about it and they reserve the day it opens. The Maine Bureau of Parks and Lands handles the reservation system and it's not bad once you figure it out. As of recent seasons the booking window has been opening in winter for the summer ahead, but verify the current rules before you plan around it.

For a private park option in that area, Wassamki Springs in Scarborough is close enough to Portland to be useful if you've got folks flying in. Full hookups, a private pond, and it's clean. Gift shop, though. You know how I feel about gift shops. Sadie disapproves on principle.

Down East: Where The Buses Don't Go

If you can make the drive — and it is a drive, Route 1 past Ellsworth slows down — Down East Maine is where I'd point you. Cobscook Bay State Park near Dennysville is one of the quietest state-run campgrounds I know of in New England. Tides run 24 feet there, which is a thing to see. Sites are spread out in the woods, electric at some, no full hookups. Bring water. The drive out feels like you're leaving the country, partly because you almost are — Canada's right there.

Further down toward Lubec, you've got South Bay Campground as a private option with hookups, smaller place. And up toward Machias, plenty of small mom-and-pop RV parks that don't show up loud on the internet. Those are the ones I like. Used to be quieter all over Down East — internet found it, like everywhere else — but it's still 70% emptier than the Bar Harbor strip in August.

Midcoast: Camden, Searsport, and Boothbay

The midcoast is the sweet spot for a lot of folks. Not as jammed as Mount Desert Island, prettier than people give it credit for, and the harbor towns are walkable.

Camden Hills State Park just north of Camden on Route 1 has electric and water hookups at a good chunk of its sites, plus a dump station. It's the rare state park where you can roll in with a real RV and not feel like you're cheating. The hike up Mount Battie from the campground gives you that postcard view of the harbor, and if you want more leg-stretching options I've got a whole rundown over on the hiking side of things and the trails list.

Searsport Shores Ocean Camping in Searsport is privately run, on the water, full hookup available. It leans artsy — they do workshops and such — which isn't my thing but the sites are well-kept and the ocean view is the real deal. Shore Hills Campground outside Boothbay is another reliable midcoast pick with full hookups and pull-throughs for the bigger rigs.

The Short List: My Honest Picks

If you held a gun to my head and made me rank, here's how I'd lay it out. Not a "best" list — I don't believe in those — just the ones I've personally been to or sent family to and heard no complaints.

• Smuggler's Den, Southwest Harbor — quieter side of Acadia, full hookups available, easier in/out than Bar Harbor proper
• Hadley's Point, Bar Harbor — family-run feel, walkable to a beach, books early
• Schoodic Woods, Winter Harbor — NPS-run, electric at some sites, mainland Acadia means no island traffic
• Camden Hills State Park, Camden — electric/water, beautiful hike right out of the campground
• Sebago Lake State Park, Casco — electric, swimming, the standard for southern Maine
• Lily Bay State Park, Greenville — Moosehead Lake, electric at some loops, true north-woods feel
• Cobscook Bay State Park, Dennysville — Down East quiet, electric only, but you'll have the place mostly to yourself
• Searsport Shores, Searsport — full hookup ocean sites, midcoast convenience
• Wassamki Springs, Scarborough — Portland-adjacent, full hookups, gift shop and all

Hookup Reality, Permits, and Things People Forget

A few hard truths from someone who used to issue permits for a living. Full hookup means water, sewer, and electric at the site. Plenty of Maine campgrounds advertise "hookups" and mean electric and water only, with a dump station on the way out. That's fine, just know what you're getting. Ask before you book, especially at the smaller private places, the website pictures don't always match.

Electric service is another gotcha. A lot of older Maine parks are 30-amp only, no 50-amp service. If you've got a big rig with two air conditioners, you'll be picking which one to run. Not the end of the world in Maine — it doesn't get Texas-hot — but worth knowing in a July heat wave. Carry a 50-to-30 dogbone adapter and a surge protector. I dont travel without either one.

State park reservations through Maine's system have gotten busier every year I've watched them, the popular sites at Sebago and Camden Hills go fast and you'll want to be ready the morning the window opens. Federal sites in Acadia go through Recreation.gov on their own schedule. For a broader look at federal campgrounds and the rules around them, the NPS site is the place to start, even if the layout's a little clunky.

One last thing — bears are around in Maine, especially inland. Food in the rig at night, trash in the bear boxes where they're provided, don't be lazy about it. And black flies in late May and early June will carry small children away. Plan for either side of that window if you can.

Gear Notes For Maine Specifically

Even if you're in an RV, you'll want some tent-and-stove kit for day trips and the occasional overflow night when your reservation doesn't line up. A decent camp stove beats firing up the RV galley for a quick coffee at a trailhead. If you've got kids who want to sleep outside one night next to the rig, a basic tent and warm sleeping bag handle the coast nights that get down into the 40s even in July. Full gear list is on the site. And browse the parks section if you're piecing together a multi-stop trip.

What I'd Actually Do

Honest take: I'd skip the Bar Harbor strip in peak July and aim shoulder season — early June or after Labor Day. Base out of Schoodic Woods or Smuggler's Den, day-trip into Acadia proper, then move west to Camden Hills for a few nights and finish at Sebago if I'm heading home through the southern part of the state. If I had a week and wanted real quiet, I'd run Down East to Cobscook Bay and just sit there with a book and the dog. That's the Maine I'd want to remember, not the one with a line at the ice cream stand.
