The best RV parks and campgrounds in Maine stretch from oceanfront bluffs near Acadia National Park to quiet state park loops on Moosehead Lake, with options ranging from full-hookup resort campgrounds to rustic lakeside sites with no hookups at all. If you’re mapping out a Maine RV trip, this list covers ten standout campgrounds across the coast, the lakes region, and the North Woods, along with what each one actually offers and a link to book direct.
Maine isn’t a state you rush through in an RV. The coastline alone could eat up two weeks if you let it, and once you get inland toward Moosehead Lake or the western mountains, cell service drops and the pace slows down even more. That’s kind of the point. Here’s where to park your rig, broken out by region so you can build a route instead of just picking randomly off a map.
1. Schoodic Woods Campground — Winter Harbor
If you want to stay inside Acadia National Park without fighting for a spot on Mount Desert Island, Schoodic Woods is the move. Schoodic Woods Campground opened in 2015, so it was designed using modern standards, and it’s the only National Park Service campground within Acadia National Park that has electricity at the campsites. Loop A sites have 20-amp outlets, Loop B sites have 20/30/50-amp outlets, and the RV sites in Loop B have water hook-ups. Just know going in: there are modern restrooms at each campground loop, but there are no showers. Flush toilets, potable running water, and a dump station are provided, as are picnic tables and fire rings in each site. Reservations run through Recreation.gov, and this side of Acadia is far less crowded than Bar Harbor proper.

2. Bar Harbor / Oceanside KOA — Bar Harbor
For the classic Acadia basecamp experience with full resort amenities, this KOA delivers. The property sits on the quiet side of Mount Desert Island, and RV sites come with full hookups, upgraded amenities, and plenty of space to relax outdoors, with some sites offering waterfront views. After a day of tidal pool exploring or carriage road biking, you can come back for locally caught seafood, ocean breezes, and a free shuttle into the park. There’s also weekly activities running Memorial Day through Labor Day if you’re traveling with kids.

3. Searsport Shores Ocean Campground — Searsport
Mid-coast Maine doesn’t get enough credit, and Searsport Shores is why it should. This family-owned spot sits on 40 acres of oceanfront land with gardens, pastures and a quarter-mile of private beach, with 125 sites ranging from RV accommodations to tent camping, along with cabins, a shared garden kitchen and an oceanfront dining pavilion. Beyond the water, there’s also another 120 acres of wooded area with trails for hiking or mountain biking. Sites include water and electric hookups up to 50 amp, and it’s right off Route 1 between Camden and Bar Harbor, so there’s no white-knuckle driving to get in.

4. Timberland Acres RV Park — Trenton
Fourteen miles from Acadia’s entrance, Timberland Acres is built specifically for RVers who want full hookups without the campground feeling cramped. The park has over 200 sites on 35 acres of wooded land, with over 80 pull-through full-hookup sites with 50-amp service that can accommodate rigs of any size, with 50 of these sites over 100 feet long. There’s a bath house and laundry facility on site, and picnic tables, fire rings, and Wi-Fi at each site. It’s been family-run since 1985, which shows in the little details, like a camp store that actually sells fresh lobster.

5. Sebago Lake State Park Campground — Naples/Casco
Sebago is Maine’s second-largest lake, and the state park campground is one of the few state-run options with actual hookups. The large campground consists of 250 campsites, about a third of which have electrical and water hookups, plus a small section of 17 walk-in tent-only sites, with the rest suitable for RVs even without hookups. Each campsite features a grill and picnic table, and within the campground there are drinking water stations, restrooms, showers, dishwashing stations, and telephones. Just an hour from Portland, this is a solid pick if you want lake access without driving to the far North Woods. Book early: reservations are recommended as this popular campground fills up early during the summer season, with the best chance of a last-minute site on weekdays.

6. Mount Blue State Park — Weld
If you want mountains instead of ocean, Mount Blue delivers big time. It’s a public recreation area covering 7,489 acres in the town of Weld, Franklin County, and the campground provides 136 sites across three loops on Webb Lake, with electric, water, and sewer hookups available for RVs up to 40 feet. Not every site has hookups, so check when you book, but the payoff is privacy: campers consistently describe the sites as wooded, spread out, and secluded, with a sandy beach and boat launch a short walk away. Cell service is spotty out here, which is honestly part of the appeal.

7. Lily Bay State Park — Greenville (Moosehead Lake)
This is the pick for anyone chasing true North Woods camping. Lily Bay sits along the east shore of beautiful Moosehead Lake just 9 miles north of Greenville, inside a 924-acre park on the southeast shore of Moosehead Lake, the largest lake in New England. Services include 90 well-spaced, wooded and waterfront campsites with fireplaces, tables, and water spigots and vault toilets, a swimming beach, picnic area and playground, a dumping station (no RV hookups), hot showers for campers, and two trailerable boat launches. There are no hookups here and no Wi-Fi, so this is more of a reset-your-brain kind of stop than a resort stay.

8. Bayley’s Camping Resort — Scarborough
If your crew wants a full-blown camping resort rather than a quiet lakeside loop, Bayley’s is the biggest swing in southern Maine. It sprawls across 750 sites in West Scarborough, operating from late April through mid-October and accommodating everything from tent campers to 75-foot motorhomes with full hookups. The resort sits on 250 acres of southern Maine’s scenic coastal countryside, just half a mile from 7 miles of pristine sandy beach, and offers two complimentary beach trolleys that run daily to Pine Point Beach and Old Orchard Beach, plus a Woodall’s-rated 5-star activities program and one of three on-site swimming pools at Bayley’s Cove Recreation and Rental Center. There’s also an adults-only section with its own pool and hot tubs if you need a break from the family chaos.

9. Wild Duck Adult Campground & RV Park — Scarborough
Also in Scarborough but the polar opposite vibe of Bayley’s, Wild Duck is strictly grown-ups. It’s a 70-site, adults-only (21+) campground designed for those seeking a peaceful and refined camping experience, from honeymooners to retirees, surrounded by Maine Audubon’s Scarborough Marsh, the state’s largest saltwater marsh. The park can accommodate RVs of all sizes with 30 and 50-amp hook-up options, gated and paved level roads, and modern restrooms, hot showers, and laundry facilities. You can even rent a canoe or kayak directly from the campground to explore the adjacent marsh, which is one of the better bird-watching setups you’ll find at any RV park in the state.

10. Libby’s Oceanside Camp — York Harbor
Closest to the New Hampshire border, Libby’s has been run by the same family since the Roaring Twenties. Established in 1923 and started by Fred Libby, it has seen many changes in camping throughout the generations and is still run by Libby’s family, now the Davidsons. It’s the only campground directly on the ocean in Southern Maine. There are 45 ocean-front sites and 18 pull-through sites, and all ocean-front sites have full hookups with water, sewer, electric, cable TV, and Wi-Fi, plus a picnic table and fire ring. Long Sands Beach sits right next door, and you’re close enough to Portsmouth, New Hampshire, and Portland, Maine, to make day trips in either direction.

How to Pick the Right Maine Campground for Your Trip
If you’re chasing Acadia, start with Schoodic Woods or the Bar Harbor KOA and build outward from there — Timberland Acres and Searsport Shores both work as quieter alternatives within striking distance. If lakes and mountains matter more to you than salt air, Sebago, Mount Blue, and Lily Bay cover the spectrum from “close to Portland” to “genuinely remote.” And if you’re traveling without kids and want a break from bingo nights and bounce houses, Wild Duck and Libby’s are both built with that in mind.
One thing worth flagging across the board: Maine’s camping season is short. Most private campgrounds open in mid-May and close by mid-October, and the state park campgrounds book up fast once summer hits. If you’ve got your eye on a specific weekend, especially anything near a holiday, call or reserve online well ahead of time rather than hoping for a walk-up spot.
