A July weekend on Sebago Lake starts on more than a mile of freshwater sand at Witch Cove Beach, towels in a line that doesn't quite reach the far shore. Kids stay in the shallows, a boat comes off the launch, and the campground in the pines is a short walk behind the beach. You swim until the light goes, then you walk back to the site.
Sebago is Maine's second-largest lake, and the campground in Naples is south of Route 302 on mixed hookup and dry loops in the trees. Summer from Memorial Day through Labor Day is the swimming season, and this is the state park campground that books out first. After mid-September the sites go first-come, as of September 2026.
Reserve the campsite before you book the van, and match the site length to what you are driving. The Sebago campground map classes sites from pop-up tents up to 20 feet through a U class over 35 feet. If you need more sleeping space or a longer pad, look at RV rentals in Portland.
Camden Hills State Park
From the open rock at the top of Mount Battie you look down on Camden Harbor, Penobscot Bay, and the islands. On a clear day Cadillac Mountain is in the distance. The park is north of Camden on US Route 1, and the campground is how you stay for the harbor and the islands.
Camping runs year-round on mixed hookup and dry sites, and several are marked drive-through. The Mount Battie Road closes at 4 p.m. daily and shuts for winter in early December or at the first snow, as of September 2026. Acadia National Park is farther up this coast, and that overnight belongs on the Acadia campervan page.
Old Orchard Beach and Kennebunk
You come south of Portland for the sand at Old Orchard Beach, 7 miles of it, with a pier and an arcade strip behind the towels. Old Orchard Beach Campground in town and Sandy Pines Campground in Kennebunkport take campervans on full hookups. Sandy Pines sits near Goose Rocks Beach.
At Popham Beach a sandbar and dune spit come out at low tide in front of Fort Popham, and Reid State Park down the shore has two beaches and a tidal lagoon. Both are day-use with no camping, and the lots fill by midday.
Bradbury Mountain State Park
Hawk-watchers stand on the open ledge at Bradbury Mountain in September and look out over the fields of Pownal. The climb is short, and the view is the fields, not the ocean. The campground is on Route 9 toward Portland, open all year, and in summer you reserve the site first, then book the van.
Freeport and Wolfe's Neck Woods State Park
The L.L. Bean flagship in Freeport never locks its doors, and a few miles out the trails at Wolfe's Neck Woods look over salt marsh and Casco Bay. Wolfe's Neck Woods State Park is day-use only, with no camping on site, and Portland Head Light at Fort Williams Park is the white tower on the dark rock for a city afternoon. Western lakes and the Downeast coast are on the Maine campervan page.
