One of the best places to start your Maine RV camping trip is in Kittery, at the state’s southern end, just over the border from Portsmouth, New Hampshire. It’s most well-known for its outlet mall shopping and massive outdoor sporting goods store, but as a former shipbuilding site, the town has lots of history to explore, too. It’s the oldest incorporated town in Maine, and if you walk its streets, you can find houses dating back to the early 1700s that are still standing. Also, while off-limits to the general public, you can observe from afar the Portsmouth Naval Prison, a castle-like Navy penitentiary that operated until the 1970s. RV campgrounds in Kittery are sparse, but a scenic 30-minute drive north of the city is the Saco/Old Orchard Beach KOA, which has loads of amenities. It features a pool, a hot tub/sauna, full hookups, and some spacious sites. If you’re looking for things to do nearby, the summer tourist town of Kennebunkport is well worth a stroll. If there’s one city in Maine that you’ve heard anything about, it’s almost certainly Portland. Like its cousin in Oregon, it has seen a population boom and an influx in gourmet restaurants and vibrant nightlife. Craft beer lovers can rejoice, as Portland also has more breweries per capita than any other city. If shopping is on your agenda, the town of Freeport is just a half an hour's drive north of Portland and has some of the best outlet mall shopping in New England. It’s also home to L.L. Bean’s flagship store, which is an experience in itself and a must for anyone who enjoys the outdoors. There are no RV campgrounds in Portland. However, camping in southern Maine isn’t difficult, as the beaches between Portland and the New Hampshire border have quite a few campgrounds to choose from. Wassamki Springs Campground in nearby Scarborough is an excellent choice with lakefront sites, full hookups, hot showers, laundry facilities, and a small store stocked with essentials. The park also offers a full activity schedule that’s great for families. A bit farther north is Bangor, home to the University of Maine, which gives it an unexpectedly cosmopolitan vibe for a town so far from a major metropolitan area. Bangor’s central location between Acadia and Baxter State Park makes it a popular stopping point for RV travelers. It’s a highly walkable city with an interesting downtown that’s filled with great shops and restaurants. If you’ve brought kids along for the adventure, check out the Maine Discovery Museum, the best children’s museum north of Boston. Bangor is also home to uber-famous horror writer Stephen King. His house looks exactly like what you’d expect, with a large metal gate festooned in bats. There are several great RV parks in Bangor. Bangor/Holden KOA is a short drive outside of town and has full hookups, 130-foot-long sites, a camp kitchen, and a swimming pool. From Bangor, head east to Maine’s spectacular coastline and Acadia National Park. Bar Harbor is the gateway to Acadia National Park and one of the most exciting towns to visit with an RV rental in Downeast Maine. Bar Harbor gets its name from the sandbar that disappears and reappears with the tide, connecting the mainland town to the more rustic Bar Island. If you know the tide schedule, you can walk out to the island for a lovely picnic. Back in town, there are loads of shops to peruse and plenty of restaurants serving up fresh lobster. To avoid the crowds in Bar Harbor and Acadia, consider camping at Bar Harbor/Oceanside KOA. Campsites have hookups for water and electricity, and some sites feature stunning water views. Additional amenities include a dog park, sports courts, and bike rentals. The campground also offers a shuttle servicing various spots around the area, so you can leave the Maine motorhome rental at the campsite. Rugged coastline, craggy mountains, and all the lobster you can handle make Maine one of the best places in the country to go camping with an RV. Additionally, the campgrounds in Maine have all the amenities you need for a stellar vacation. Just be sure you budget enough time to see all the amazing sights that the Pine Tree State has to offer.
