Acadia National Park RV Camping: Size Limits, Campgrounds & the Best Way to See Mount Desert Island

Acadia National Park is the Northeast's most visited national park for good reason — the dramatic granite coast, the 27-mile Park Loop Road, the carriage roads system that winds through birch forest and over stone bridges, and Cadillac Mountain, where you can watch the first sunrise in the US on clear mornings. Acadia is also one of the most logistically challenging national parks for RV travelers. Here's how to plan a trip that avoids the common pitfalls.

The RV Size Situation at Acadia

This is the most important thing to know before planning an Acadia RV trip: the main Park Loop Road is not recommended for vehicles over 20 feet in length on the section south of Sand Beach. The sharp turns on the one-way road toward Otter Cliff and Thunder Hole can be tight for larger rigs.

Blackwoods Campground (within the park): Maximum RV length is 35 feet. No hookups. Reservations required from May through October — book on recreation.gov as soon as windows open (usually 6 months ahead).

Seawall Campground (within the park): Accepts RVs but with limited sites for longer rigs. Some sites are walk-in tent only. Located on the quieter western side of the island — less traffic than Blackwoods.

Schoodic Woods Campground (Schoodic Peninsula): The least-known Acadia campground is often the best RV option — newer, paved sites, accepts RVs up to 35 feet, full hookup sites available. The tradeoff is that it's on the Schoodic Peninsula, 45 minutes by road (or 75 minutes by the free ferry) from the main Mount Desert Island section of the park. For RVers who want hookups and less crowding, this is an excellent choice.

Alternative: Bar Harbor Area Commercial Campgrounds

Many RVers visiting Acadia choose to stay at commercial campgrounds in Bar Harbor or the surrounding area and use the Island Explorer shuttle bus (free, runs throughout the park in summer) to access park destinations without driving their RV on the narrow park roads.

Best commercial options:

• Bar Harbor KOA: Full hookups, large sites that can accommodate big rigs, pool and amenities. About 4 miles from the park entrance on Route 3.
• Bass Harbor Campground: Quieter location on the western side of the island. More rustic than KOA, with some nice wooded sites.
• Lamoine State Park: Beautiful Frenchman Bay views, affordable state park rates, 35-foot maximum. Book early — it fills fast in summer.

The Park Loop Road (and How to Navigate It in an RV)

The 27-mile Park Loop Road is the iconic way to see Acadia's coastal scenery — Thunder Hole, Otter Cliffs, Sand Beach, Jordan Pond, and the Cadillac Mountain summit road.

What RVers can do: Most of the one-way section (Sand Beach to Otter Cliffs) is manageable in a motorhome up to 30-35 feet if you're comfortable on tight roads. The two-way section and Jordan Pond are easily accessible. Cadillac Mountain Summit Road accepts RVs.

The Island Explorer shuttle strategy: Park your RV at a designated staging area (Village Green in Bar Harbor, or the large lot near the Visitor Center), take the Island Explorer shuttle to the most crowded spots (Sand Beach, Thunder Hole, Ocean Path), and drive the loop sections that work for your rig size. This is actually the superior experience — the shuttle lets you stop anywhere on the route and explore on foot without dealing with parking.

What to Do at Acadia

Carriage Roads: John D. Rockefeller Jr. donated 57 miles of horse-drawn carriage roads with 17 hand-crafted stone bridges to the park. These roads (motor vehicles prohibited) are accessible by bicycle, horseback, and foot. Renting bikes in Bar Harbor and spending a day on the carriage roads is one of the best experiences at Acadia. Accessible from the Jordan Pond House parking area.

Cadillac Mountain: At 1,530 feet, Cadillac is the highest peak on the eastern seaboard. The summit road (open to vehicles including large RVs) reaches the top for panoramic views of Frenchman Bay, the islands, and on clear days, the entire region. Sunrise on Cadillac is a bucket-list experience — timed-entry permits are required for sunrise visits from May through October (book on recreation.gov).

Jordan Pond House: Afternoon tea and popovers on the lawn overlooking Jordan Pond and the Bubbles mountains. This is a 100-year tradition at Acadia. The parking area handles moderate-size RVs — arrive early to get a spot.

Thunder Hole: A cleft in the granite coast that produces a dramatic thunderclap and spray when the wave timing is right. Best 2-3 hours before high tide with a moderate to large swell. Check tide charts before you go.

Isle au Haut: A remote island accessible by mail boat ferry from Stonington (45 miles from Bar Harbor). A section of Acadia National Park lies on the island with hiking trails and a small campground — truly remote. Only accessible by boat, and the small ferry doesn't carry vehicles.

When to Visit

Peak season (July–August): Crowded and expensive. Bar Harbor is one of the busiest tourist towns in New England in summer. Campground reservations must be made months ahead. Parking in the park is extremely limited on sunny summer days — use the shuttles.

Shoulder season (May–June, September–October): Far better for RVers. October is particularly spectacular — fall foliage on Mount Desert Island peaks in mid-October and the crowds are manageable. September has warm enough days for swimming and hiking without summer congestion.

Off-season (November–April): Park campgrounds closed. Bar Harbor significantly quieter. Some hiking and scenic driving remains possible on good days. Winter views of Frenchman Bay with no crowds can be exceptional.
