Isle au Haut: The Ultimate Family Guide to Acadia's Remote Island Gem
Why Isle au Haut Feels Like Acadia's Best-Kept Secret
Isle au Haut is the kind of place that makes people wish they could hit a pause button. This quieter, wilder version of Acadia does just that the moment you step off the boat. The island slows you down in the best possible way. No crowds. No traffic. No cell service worth bragging about.
Families who come here usually want the same thing. It offers a quiet place to connect with one another, provides a real adventure, and gives kids the chance to roam free all while disconnecting from their phones.
Isle au Haut rewards you for showing up with curiosity instead of convenience. And honestly? That's part of its magic.
Getting There: The Mail Boat That Feels Like an Adventure All on Its Own
Most visitors start their Isle au Haut journey in Stonington, where the town's mail boat heads out year-round. Calling it a "ferry" doesn't do it justice. On any given day you might find yourself standing next to island residents hauling groceries, fresh produce, or the day's mail.
Quick Details:
- Departs: Stonington, Maine
- To Town Landing: year-round
- To Duck Harbor: May 19–October 13 (2025)
- Boarding: first-come, first-served (arrive 30 minutes early)
- Pets: welcome on the boat (but not in Duck Harbor Campground)
- Parking: available at the Stonington wharf
- Vehicles: not allowed—there is no auto ferry
And that last point is important. The lack of cars is exactly why the island feels so peaceful. You explore on foot or bike, which instantly shifts your mindset into "island time."
Best Isle au Haut Hiking Trails for Families
Isle au Haut packs over 18 miles of trails into a surprisingly diverse landscape. One minute you're walking along a rocky cliff, the next you're ducking into spruce forest or hopping across logs over a marsh.
Eben's Head Trail (2.9 miles / easy–moderate)
If you only have time for one hike with younger kids, this loop is the winner. It meanders along the coastline with several flat rocks perfect for a picnic. Elevation gain stays gentle (105–160 feet), and the views roll out quickly.
Duck Harbor Trail (7.6 miles / moderate)
You'll move through patches of moss, short boardwalks, and rocky coastlines, with plenty of quiet pockets along the way. Families appreciate how often the landscape shifts without feeling dramatic about it.
Duck Harbor Mountain (2.4 miles / strenuous)
Short but spicy. This climb packs about 300 feet of steep elevation and a bit of hand-over-foot scrambling. The payoff? An island panorama that kids love because it feels like they're standing on top of the world.
Western Head Trail (4.2 miles / moderate)
Ocean views the whole way, plus the chance to cross (at low tide!) to Western Ear—a tiny rock island that feels like secret territory. Check the tide charts unless you want the ocean deciding your schedule.
Goat Trail (6.8 miles / moderate–strenuous)
If wild coastline is your family's happy place, this is your trail. Granite cliffs, crashing surf, and the famous cobblestone beach at Squeaker Cove. Keep an eye out—this is where hikers sometimes spot mink darting between rocks.
Median Ridge (1.5 miles / moderate)
A quieter, more forested walk with rock gardens and a cedar swamp. Great as a warm-up or connector.
Long Pond Trail (9 miles / moderate–strenuous)
Perfect for families with hardy hikers who want solitude. You'll dip about 375 feet toward the pond and pass old stone walls and those smooth "dinosaur egg" rocks locals love pointing out.
Bowditch Trail (7.4 miles / moderate)
Blueberries, wildflowers, and the island's highest ridgeline make this one feel especially rewarding. The climb is gradual and scenic the entire way.
Nat Merchant Trail (5.6 miles / easy)
An easygoing connector with a watery surprise: Merchant Brook sometimes runs right down the trail.
Camping at Duck Harbor: For Families Who Love a Challenge (and a Reward)
Duck Harbor Campground is one of Acadia's most beloved backcountry spots—and also one of its simplest.
What to expect:
- Five rustic lean-tos (tents must fit inside)
- Fire rings (use only dead/downed wood from the area)
- Composting toilets
- No potable water
- A hand pump for untreated water 1,600 ft from the shelters
- No pets
- Quiet hours 10 pm–8 am
- Reservations required (open April 1 on Recreation.gov)

If the Duck Harbor boat isn't running when you visit, you'll hike more than 4 miles from Town Landing to reach camp—something families often remember as part of the adventure.
Camping here forces you to slow down, reset your senses, and rely on simple routines. Kids tend to remember the sound of the wind in the spruces or the glow of headlamps on the lean-to ceiling long after the trip is over.
What's (Actually) on the Island
Isle au Haut is a real working island, not a resort town. You won't find restaurants, gift-shop rows, or an ice cream shop on every corner.
What you will find:
Shore Shop Gifts: A charming shop offering island-made products, crafts, Maine wine, and sometimes fresh lobster.
The Island Store: Groceries, hardware, snacks, simple essentials. Perfect for topping off your supplies.
Seasonal Eats: In summer, watch for small vendors like The Maine Lobster Lady, who slings lobster rolls that taste like summer on a bun.
Most families pack lunches or buy groceries at The Island Store. On Isle au Haut, eating is more picnic blanket than plated entrée.
Wildlife, Wildflowers & Unexpected Magic
Isle au Haut has a quiet way of surprising you.
You might see:
- Mink darting along the Goat Trail
- A lone beaver (rare, but photographed on Eli's Creek!)
- Endless seabirds
- Waves of spring wildflowers
- Red blueberry barrens glowing in October
Wildlife is abundant but subtle. Kids often get more excited about tide pools or the perfect skipping stone than anything else—and honestly, the simplicity of it all is what makes so unique.

Most families visit between late April and mid-November.
Here's how the seasons feel:
