If you’re wondering where to park your rig in the Pine Tree State, the best RV parks in Maine cluster around three things: the coast, the lakes, and Acadia National Park. Below are ten campgrounds that consistently earn strong reviews for their hookups, amenities, and locations, with links straight to their official sites so you can check availability yourself.
Maine isn’t a state where camping gets old fast. Maine has more miles of coastline than California, a stunning 3,478 miles, and travelers heading to the state should make sure to check out the coastline and off-shore islands. Whether you want to fall asleep to waves on Penobscot Bay or wake up to loons on a mountain lake, there’s a campground built for that.
1. Searsport Shores Oceanfront Campground (Searsport)
This is the campground people mean when they say “Maine’s premier oceanfront RV park.” The campground offers RV sites, tent sites, and simple cabins across 40 wooded acres, with the accessible cobblestone shore a short walk away. It’s family-run, and it shows: it has been recognized over the years by the Boston Globe, USA Today, Trailer Life, and Yankee Magazine, and voted “Best of the Best” by the Republican Journal for more than twenty years. Sites come with fireplaces, picnic tables, and both 30- and 50-amp hookups, plus kayaking, hiking trails, and a dog park.

2. Schoodic Woods Campground (Acadia National Park)
If you want to say you camped inside Acadia without the Bar Harbor crowds, this is your spot. The campground features 94 camping sites, 8.5 miles of bike paths, and 4 miles of hiking trails, and all sites except group and hike-in sites have electric hookups, with B-Loop sites offering electric and water, plus flush toilets, potable running water, a dump station, and paved roads. It sits on the Schoodic Peninsula, the only mainland section of Acadia, about 1.5 miles southeast of Winter Harbor. Book through Recreation.gov, not the campground directly.

3. Sandy Pines Campground (Kennebunkport)
Sandy Pines blurs the line between traditional RV camping and glamping, and it works. The campground offers glamorous safari tents, huts, cottages, and Unique Retreats alongside 320 wooded campsites and scenic salt marsh views, with onsite amenities including a saltwater pool, playground, kayak launch, and a General Store. It sits just a mile from Goose Rocks Beach, and RV sites include picnic tables, fire pits, and access to modern bathhouses.

4. Lake Pemaquid Campground (Damariscotta)
This one leans into “family activity headquarters” more than “quiet retreat.” The campground features 300 spacious sites accommodating RVs up to 45 feet, with full hookups including 30/50 amp electric, water, and sewer connections. Guests can enjoy a heated swimming pool, hot tub, playground, mini-golf, an enclosed game room, and pet-friendly fishing, boating, canoeing, and kayaking on Pemaquid Lake. It’s busy in peak season, so this suits families more than folks chasing total silence.

5. Bayley’s Camping Resort (Scarborough)
Bayley’s is enormous by Maine standards and built for big-rig comfort. It sits only a half mile from seven miles of ocean beach, with 700-plus sites accommodating the largest RVs down to wilderness tenters, plus a mini-golf course, swimming pool, two hot tubs, a bar and grill, a game room, a rec center, a playground, and picnic areas with fire circles and grills. The resort also runs two beach shuttles and a Seaside Square restaurant with evening entertainment, plus onsite kayaking and free WiFi.

6. Bar Harbor / Oceanside KOA Holiday (Trenton)
This is the go-to base camp for Acadia if you want KOA consistency with oceanfront views. Accommodations range from RV and tent sites to camping cabins, deluxe cabins, and Airstream trailers, with private oceanfront access, sunset views, bike rentals, playgrounds, a jump pad, sports courts, and a KampK9 dog park. The RV park offers full hookup options with 50-max amps and both pull-thru and back-in sites, and on-site amenities include the Lobster Trap Cafe for fresh seafood dinners.

7. Cathedral Pines Campground (Eustis)
Head inland toward the Bigelow Mountains and you’ll find this quieter, more forested option. The campground offers 115 sites across 300 acres of tall red pine trees, with sites situated for privacy, a rec hall, laundry, and boating and fishing access. Waterfront sites face west across Flagstaff Lake toward the Bigelow Mountains, with facilities including electric, water, and sewer hookups, a dump station, showers, flush toilets, and WiFi in some areas. It’s a favorite for anyone who wants big, level sites without feeling stacked on top of the next rig.

8. Naples KOA Holiday (Naples)
Sitting in the Lakes Region between Sebago Lake and Long Lake, this KOA is a smart pick if you want easy access to swimming, boating, and a short drive into Portland. The campground operates as a KOA property on the edge of Long Lake, running from late April through mid-October, with full hookup sites accommodating rigs up to 50 feet plus water, electric, and sewer connections. Amenities include WiFi, a dump station, clean bathhouses, and on-site activities including water slides and a pool.

9. Sennebec Lake Campground (Appleton)
This midcoast lake campground trades ocean views for mountain and water views, and a lot of repeat campers seem fine with that trade. It offers 40 beautiful forested acres of lakefront, with a location overlooking the lake and mountains that gives guests a feeling of serenity and a chance to reconnect with family and friends. Kids get a beach playground, arcade, and basketball court, while lakefront RV and tent sites come with water, electricity, WiFi, fire pits, and picnic tables.

10. Balsam Woods Campground (Guilford)
For anyone chasing Moosehead Lake or the Appalachian Trail’s northern terminus at Katahdin, this is the practical last stop before wilderness territory. It sits just a half hour south of Moosehead Lake, Maine’s largest lake, and 60 miles as the crow flies from Mt. Katahdin in Baxter State Park, with direct access to 1,000 miles of ATV trails, a camp store, pool, classic rec hall, playground, and 30- and 50-amp RV sites. One reviewer summed it up simply after parking a 40-foot fifth wheel there without issue, calling it a “awesome place to stay” with a “beautiful campground, friendly staff”.
What Amenities Should You Expect at Maine RV Parks?
Amenities vary a lot depending on whether you’re coastal, lakeside, or deep in the mountains, but many RV parks and RV resorts in Maine offer amenities such as showers, toilets, laundry, WiFi, boat ramps, playgrounds, and watersport rentals like canoes and kayaks. The bigger family resorts add pools, mini-golf, and organized activities, while the smaller lakeside and mountain campgrounds tend to favor privacy and quiet over programming.
When Should You Book a Maine Campground?
Maine’s camping season is short and competitive. If you want a spot at one of the state park campgrounds, reservations are booked through the Bureau of Parks and Lands online system at CampWithME.com, opening in early February each year, with stays capped at 14 nights and a two-night minimum on weekends until July 1. Acadia’s park campgrounds follow their own schedule too: for Blackwoods, Seawall, and Schoodic Woods, 90 percent of campsites are released six months in advance on the first of each month at 10 a.m. Eastern, with the remaining 10 percent released 14 days ahead of arrival on a rolling basis. Private resorts like Bayley’s and Sandy Pines fill up just as fast for July and August weekends, so don’t wait until June to start planning.
Final Thought
You really can’t go wrong picking a home base by what kind of trip you want. Chase oceanfront sunsets at Searsport Shores or the Bar Harbor KOA, go full family-resort mode at Bayley’s or Lake Pemaquid, or disappear into the pines at Cathedral Pines or Sennebec Lake. Whichever you choose, book early, bring bug spray, and don’t skip the lobster.
