For sand beaches and no RVs, book Hermit Island. With a dog, pick Searsport Shores or Sagadahoc Bay. For a night on your own spruce island, paddle to Warren Island.

Falling asleep to waves on rock is the reason people camp the midcoast. Most “coastal” campgrounds in Maine sit a drive from the water. The ones below put you on the saltwater, with a tent site over the bay or a short walk to a beach. Each passed one test: can you see or reach the ocean from your site?
The 8 Best Oceanfront Campgrounds in Midcoast Maine
Five campgrounds get full write-ups below, from Phippsburg up to Camden. Three more campgrounds round out the eight: an oceanfront farm campground near Portland, a saltwater campground on a tidal bay in Wiscasset, and a small shore campground in South Thomaston. Fees and site counts come from each campground’s page on this site or its own website. Tap a pin for its page.
- Near Portland: Wolfe's Neck Freeport · Casco Bay · Tents and RVs Once called Recompence Shore, on a working farm with Casco Bay tidal shore. Book direct, year-round. Pictured: neighboring Wolfe's Neck Woods State Park.
- Tidal bay: Chewonki Campground Wiscasset · Montsweag Bay · Tents and RVs 47 sites overlooking the salt water on Chewonki Neck, with a pool for low tide when the bay drains to mudflats. Pets welcome; book by phone.
Lobster Buoy Campsites in South Thomaston, south of Rockland, is the eighth: a small campground of about forty sites for tents and RVs on more than 400 feet of shore, where no site is more than 150 yards from the water (Lobster Buoy). It allows one leashed dog per site and has sites with water and electric hookups, but no sewer hookups.
Phippsburg Peninsula
The Phippsburg peninsula south of Bath and neighboring Georgetown Island hold the two best tent-camping spots on the midcoast. Both sit at the end of long two-lane roads, which is part of why the sites are so good.
1. Hermit Island
Hermit Island is a 255-acre peninsula at the tip of Small Point, with Casco Bay on three sides and eight named beaches, including Head Beach, pictured. No RVs or hard-topped campers are allowed: tents, pop-up trailers up to 25 feet and truck campers only (Hermit Island). That rule keeps it quieter than anywhere else on the coast, and the Ocean View sites put you right over the water.
There is no online booking. For a week or more, mail a letter with a $125 deposit by the second week of December; requests are drawn at random in January. Shorter stays open by phone in March. There is no cell service or WiFi, which most people decide is a feature.
Nearby: Popham Beach State Park (10 minutes), Fort Popham at the mouth of the Kennebec, and Bath for groceries (20 minutes).
- Sites
- 271, tents, pop-ups and truck campers
- Rates
- $52 to $81 a night in season (2026, plus tax)
- Booking
- Mail or phone only
- Cell service
- None
Hermit Island does not allow dogs, no exceptions. Camping on the midcoast with a dog? Searsport Shores and Sagadahoc Bay welcome them.
2. Sagadahoc Bay Campground
Sagadahoc Bay sits on Georgetown Island above the tidal flats of the bay. Oceanfront sites are right at the water’s edge, and bluff sites sit about 30 feet up with views across the bay. Sunset from the waterside sites is the reason to book.
What makes Georgetown Island work is Reid State Park, pictured at low tide, one of the few sandy-beach state parks on the midcoast and 15 minutes south on the same island. Camp on the bay and spend the beach day at Reid. Pets are welcome, so this is the dog-friendly alternative to Hermit Island.
Nearby: Reid State Park beaches, Five Islands Lobster Co., and Bath (20 minutes).
- Sites
- About 75, plus cabins
- Rates
- $26 to $170 a night by site type
- Dogs
- Two pets per site included
- Sand beach
- Reid State Park, 15 minutes
Sagadahoc Bay is a tidal bay, so swimming there depends on the tide chart. Low tide brings mudflats and exposed ledge: great for tide pools, poor for a swim. Hermit Island’s beaches are sand, but the tide still changes them a lot. At either spot, plan beach time for mid to high tide, or use the big sand beaches at Reid or Popham.
Penobscot Bay
The upper midcoast around Searsport, Camden and Islesboro has the most dramatic water, with the Camden Hills rising right behind the bay.
- Sites
- About 111
- Walk-in tent sites
- $61 to $74 a night
- Dogs
- One per site, leashed, with an off-leash dog park
- Season
- May through October
3. Searsport Shores Ocean Camping
Searsport Shores is a family-run campground directly on Penobscot Bay. Walk-in tent sites line the bluff above the water, and RV sites sit farther back. The family that runs it added working art studios and an organic kitchen garden, plus a private launch for kayaks and small boats.
It is the easiest oceanfront pick on the midcoast if you have a dog: leashed dogs with current rabies and distemper paperwork are welcome, and there is an enclosed off-leash dog park. You can swim at low to mid tide where the bottom is sandy, but the bay is cold, so most people kayak or explore tide pools instead.
Nearby: Belfast (10 minutes) for dinner and breweries, Fort Knox and the Penobscot Narrows Observatory (15 minutes north), and Moose Point State Park (2 miles south), a day-use park with no camping, good for a picnic and a walk on the shore.
4. Warren Island State Park
Warren Island is the most remote oceanfront camping on this list. It is a 70-acre spruce island in Penobscot Bay off Islesboro, about three miles off Lincolnville, and you can only reach it by your own boat. Grindle Point Light, pictured, stands on Islesboro, the island next door.
Once ashore you get 12 campsites and three Adirondack shelters, with no power, no running water and no crowds. Trails wind through the woods and along the shore. It was Maine’s first state park built for boaters, and it is a stop on the Maine Island Trail.
The park says the Lincolnville ferry terminal lot now sells parking passes only to ferry customers, so arrange parking in Lincolnville or launch from Belfast. Book sites through CampWithME (2026 fee schedule).
- Sites
- 12 plus 3 Adirondack shelters
- Camping fee
- $15 resident, $25 non-resident a night
- Access
- Your own boat only
- Season
- Memorial Day to September 15
Warren Island has no road and no ferry. Crossing Penobscot Bay in a canoe or sea kayak is real open water, with wind, boat traffic and cold water. Only experienced paddlers should try it, and everyone should check the marine forecast and tide before launching.
5. Camden Hills State Park
Camden Hills has no swim beach, so it is the asterisk on this list. It earns a spot as the best base for camping near the Penobscot Bay shore and the town of Camden, pictured from above.
Hike or drive up Mount Battie for the view over Camden Harbor, or climb Mount Megunticook (1,385 feet). Then you are minutes from Camden for dinner, and Laite Beach is about 10 minutes away for a swim. The campground is wooded and quiet, with hot showers, and early October foliage weekends fill fast. State park campsites for the 2027 season go on sale Thursday, February 4, 2027, at 9 a.m. (Maine State Parks).
Nearby: Camden Harbor and downtown, the Mount Battie summit, and the schooner fleet in the harbor.
- Sites
- 107, some with hookups
- Rates
- $25 resident, $35 non-resident; $35 and $45 with water and electric
- Swim
- No beach in the park
- Booking
- Opens February 4, 2027
What About Downeast?
Push past the midcoast into Downeast and the crowds thin out fast. McClellan Park in Milbridge is a small town-owned campground on a rocky point over Narraguagus Bay, with sites above the water for a fraction of a private campground’s rate.
Ocean Wood Campground near the Schoodic Peninsula and Cobscook Bay State Park, pictured, are the other coastal options farther east. Cobscook has some of the biggest tides in the Lower 48. They are a longer drive, but you get solitude you won’t find around Camden in July.
- McClellan Park
- About 13 sites, $15 a night, first come
- Cobscook Bay
- 106 sites, tides averaging about 18 feet
When to Camp the Coast
The midcoast camping season runs roughly Memorial Day through Columbus Day. July and August bring the warmest water (still only the low 60s on the bay), the most crowds and the highest rates. Early June and September are the locals’ secret: the same beaches and bay, fewer people, and shoulder-season prices at private campgrounds. September water is warmer than June’s.

Coastal nights stay cool in midsummer, so pack a warmer sleeping bag than you would inland. Our Maine sleeping bag guide has temperature ratings that suit the coast, and the family tent guide covers shelters that stand up to wind off the water. Oceanfront sites take more wind than inland campgrounds. Bring extra stakes, guy out your rain fly, and expect morning fog that burns off by midday. A freestanding tent that doesn’t depend on perfect staking is worth it on exposed sites.
Frequently Asked Questions
Where can you camp right on the ocean in midcoast Maine?
Hermit Island in Phippsburg, Sagadahoc Bay Campground on Georgetown Island, and Searsport Shores on Penobscot Bay all have sites directly on the water. Warren Island State Park off Islesboro is a boat-access island where every site is oceanfront. Camden Hills State Park has bay views but no swim beach.
Which midcoast campground has the best beach?
Hermit Island has eight named beaches on its own peninsula. For sandy-beach day trips, Sagadahoc Bay Campground is 15 minutes from Reid State Park, one of the only sandy-beach state parks on the midcoast. Most other coastal Maine campgrounds have rocky or tidal shorelines rather than sand.
Can you camp on the ocean in Maine with a dog?
Yes. Searsport Shores Ocean Camping on Penobscot Bay allows leashed dogs with current rabies and distemper paperwork and has an enclosed off-leash dog park. Sagadahoc Bay Campground also welcomes pets, two per site. Hermit Island does not allow dogs at all.
How early do you need to book oceanfront camping on the midcoast?
Maine state parks (Camden Hills, Warren Island) open reservations for the whole season in early February, on February 4 for 2027, and fill fast for peak weekends. Hermit Island has no online booking: week-long requests go by mail by the second week of December and are drawn in January, and shorter stays book by phone from March. Private campgrounds like Sagadahoc Bay and Searsport Shores book directly and fill their waterfront sites by March or April for July and August.
Is the water warm enough to swim on the midcoast coast?
Barely, and only in late summer. Penobscot Bay and the tidal bays stay in the low 60s even in August. Tidal-flat campgrounds like Sagadahoc Bay only have a real swim window at mid to high tide. For warmer swimming, use sandy beaches like Reid or Popham, or head to an inland lake.
Do you need a boat to camp at Warren Island State Park?
Yes. Warren Island in Penobscot Bay has no ferry and no road. You reach it by your own canoe, kayak, or boat; the island sits about three miles off Lincolnville. Only experienced paddlers should attempt the crossing, and everyone should check the marine forecast first.
