45 Miles of Carriage Roads: 8 Best Loops With a Dog

Rockefeller built 45 miles of car-free, gently graded, packed-gravel road across Acadia between 1913 and 1940. For a dog it is worth more than all the famous summits combined. Eight loops ranked.

Acadia's carriage roads are the best thing in any American national park for a dog, and the reason is structural rather than scenic.

Between 1913 and 1940, John D. Rockefeller Jr funded and directed the construction of 45 miles of broken-stone roads, roughly 16 feet wide, engineered with three layers of rock, a pronounced crown for drainage, stone culverts, and wide ditches. He financed 16 of the 17 stone-faced bridges that carry them over streams, waterfalls, and cliffsides.

They are closed to motor vehicles. They are wide enough that a leashed dog and a passing cyclist are never in each other's way. The surface is packed gravel rather than granite slab, which is far kinder on pads than Acadia's trails. The grades are gentle, because they were built for horses pulling carriages. And every intersection carries a numbered cedar signpost that matches the numbers on park maps, so navigation is genuinely easy.

For an older dog, a large dog, a dog recovering from something, or a wet Maine day when the granite is slick, the carriage roads are the answer to almost every question.

Eight loops below, easiest to hardest. Distances are approximate and vary slightly with route and source.

1. Witch Hole Pond Loop, roughly 3.3 miles

The gentlest introduction on the network and the right first outing with a dog.

A rolling loop through open woods and beaver ponds on the northern end of the system, close to Bar Harbor and reached from the Duck Brook Road or Paradise Hill area. Low elevation change, plenty of water in view, and short enough that a dog fresh off a long drive can manage it comfortably.

Best for: first day, senior dogs, puppies, anyone easing in.

2. Jordan Pond Carriage Road Loop, roughly 3.4 miles

The carriage road circuit around the eastern side of Jordan Pond, with the Bubbles rising at the far end. Short, spectacular, and the single most photographed stretch of the network.

Two warnings. Jordan Pond parking fills earliest of anywhere in Acadia, so arrive before 8am or use the fare-free Island Explorer, which takes leashed or crated pets. And note that the Bubble and Jordan Ponds Path, a separate hiking trail, is on the Park Service's list of routes not recommended for pets. Stay on the carriage road.

Best for: the classic view without the classic difficulty.

3. Day Mountain, roughly 3.5 miles

The only carriage road in Acadia that climbs to a summit, which makes it unique on this list. A steady spiral up through spruce and birch to a modest top with views south over the water and the Cranberry Isles.

Because it is a carriage road rather than a trail, a dog gets a summit with no scrambling, no ladders, and no exposed slab. That combination barely exists elsewhere in the park.

Best for: a summit view with a dog that cannot climb.

4. Aunt Betty Pond Loop, roughly 5.4 miles

Quieter than anything near Jordan Pond, running through wetland, beaver flowage, and mixed forest west of Eagle Lake. Gentle throughout.

Best for: avoiding people, and for a dog that finds crowds stressful.

5. Duck Brook and Paradise Hill, roughly 5.4 miles

Starts at the Duck Brook Bridge, a triple-arched stone bridge that is among the most impressive structures Rockefeller built, and climbs gradually to viewpoints over Frenchman Bay.

Closest access to Bar Harbor of any loop here, which makes it the efficient choice if you are staying in town and short on time.

Best for: the best bridge on the network, and easy access from town.

6. Eagle Lake Loop, roughly 6 miles

A full circuit of Acadia's second-largest lake, with water beside you for most of it. Wide, well-graded, and popular with cyclists, so a dog needs to be steady about bikes passing.

Important: Eagle Lake is a public water supply. Like most of Acadia's lakes, pets are not permitted in the water, year round, not seasonally. Walk beside it and carry your own water.

Best for: a real distance day on easy footing.

7. Amphitheater and Hadlock Loop, roughly 5.4 miles

Arguably the most beautiful loop on the network. It runs through the Amphitheater valley and crosses the Hemlock Bridge and the Waterfall Bridge, the latter overlooking Hadlock Brook Falls, which is at its best after rain.

Some sustained gradient, but nothing steep by trail standards.

Best for: the two best bridges and a waterfall, with a fit dog.

8. Around Mountain Loop, roughly 11.3 miles

The big one. A long circuit around Sargent and Penobscot mountains, taking in the high carriage roads with the widest views on the system, and passing several of the finest bridges.

Eleven miles on packed gravel is a serious day for a dog that has not built up to it. Do not make this day one. Do not attempt it in high summer heat without an early start and a lot of water.

Best for: a fit, conditioned dog and a full day.

The bonus loop that is not in the park

Little Long Pond, on Land and Garden Preserve land near Seal Harbor, carries its own network of red-stone carriage roads adjoining Acadia's. It is not national park land, and its rules are different in one important way.

Dogs may be off leash here, provided they remain in visual and voice contact and under genuine voice control. Reported seasonal conditions require leashes between 10am and 4pm from 1 May through 30 September, so the off-leash window in summer is early morning and late afternoon. Rules are posted on site and should be read at the trailhead rather than assumed.

Other Preserve specifics: dogs are welcome year round during daylight hours in all areas except the Preserve gardens, meaning Asticou Azalea Garden, Thuya Garden, and the Abby Aldrich Rockefeller Garden, where only service animals are permitted. Swimming is allowed only at four designated, signed areas. Dog waste stations sit at the bottom of the Friends Trail and in each parking lot. Bikes are not permitted on the Preserve carriage roads.

For a dog that wants to run rather than walk, this is the only realistic option in the Mount Desert Island area, and it is worth planning a morning around. Confirm current rules on the Land and Garden Preserve site before you go.

Sharing the carriage roads properly

The roads carry walkers, runners, cyclists, and horse-drawn carriages, and the etiquette matters more with a dog than without one.

Six-foot leash, no longer. The park rule, and it applies on every mile of carriage road.

Keep your dog on one side. A dog on a long lead across a 16-foot road is a tripwire for a cyclist coming round a corner at speed.

Horses have absolute right of way. Carriage roads still carry horse-drawn carriages. Step well off, shorten the lead, and stand still. A dog lunging at a horse in harness is the worst outcome available on this network.

Announce yourself at blind bends. The grades and curves mean cyclists appear with little warning.

Pick up, and carry it out. Waste receptacles exist but are not at every intersection.

When the carriage roads are the right call

On a wet day. Acadia's granite grows a thin film when damp and a dog's grip on it is poor. Packed gravel is not affected.

With a large or heavy dog. No ladders, no rungs, no slab, and nothing you would have to lift a dog over. The Park Service's own pet page lists both the trails closed to pets and the ones that are legal but not recommended, which is the list a heavy dog's owner should read first.

With an older or arthritic dog. Gentle, consistent grades and a forgiving surface.

When you want distance. Eleven miles of easy grade is achievable in a way that eleven miles of Acadia trail is not.

When the trails are busy. Forty-five miles absorbs crowds far better than the handful of famous summits.

If you want more than gravel underfoot, pick from the park's dog-legal trails rather than the summits, and check the not-recommended list before you commit.

Practical notes

Carry water. Most Acadia lakes are public water supplies and closed to pets, so there is less drinking water available than the map suggests.

Check for ticks afterwards. Maine has a substantial tick population and the grassy road edges are prime habitat. Check thoroughly after every outing.

Winter changes things. Sections of the carriage roads are groomed for cross-country skiing in winter, and etiquette around ski tracks applies. Conditions vary year to year, so check with the park.

Parking is the constraint, not the roads. Duck Brook, Eagle Lake, and Jordan Pond all fill early. The Island Explorer is fare-free and takes leashed or crated pets, though not on the seats.

For a long gravel day, what to pack for a hotel stay with a dog covers the water and bowl side of it, and traveling with a senior dog is worth reading if yours is older, since a flat surface tempts you into more miles than the dog wants.

Save a vet number, from emergency vet, what to know, and if you have not booked, search the PetCompass hotel directory or filter to hotels that allow large dogs.

Conclusion

Forty-five miles of car-free, gently graded, packed-gravel road, built between 1913 and 1940, carried over 17 stone bridges, and signposted at every intersection. There is nothing else like it in the national park system, and for a dog it is worth more than all of Acadia's famous summits combined.

Start with Witch Hole Pond at roughly 3.3 miles. Take Day Mountain if you want a summit without a scramble. Take the Amphitheater and Hadlock loop for the bridges. Save Around Mountain at 11.3 miles for a conditioned dog on a cool day.

And if your dog needs to be off leash rather than beside you, Little Long Pond on the Land and Garden Preserve is the one place near Acadia that allows it.

Trail conditions, seasonal rules, shuttle schedules, and preserve policies change. Confirm current details before you go. Then find the trail your pet will wag "yes" to.

Frequently asked questions

Can dogs go on Acadia's carriage roads? Yes, on all 45 miles, on a leash no longer than six feet. The carriage roads are the most dog-accessible part of Acadia National Park and the best option for large, older, or less agile dogs.

What is the easiest carriage road loop with a dog? Witch Hole Pond, at roughly 3.3 miles, with gentle elevation change and beaver ponds along the way. It sits near Bar Harbor and makes a good first outing after a long drive.

Can my dog swim in Eagle Lake or Jordan Pond? No. Many of Acadia's lakes, including Eagle Lake, are public water supplies and closed to pets year round rather than seasonally. Carry your own water.

Where can a dog be off leash near Acadia? Little Long Pond, on Land and Garden Preserve land near Seal Harbor, permits off-leash dogs that remain in visual and voice contact and under voice control. Reported seasonal rules require leashes between 10am and 4pm from 1 May to 30 September. Check the posted signs on arrival.

Are bikes and horses a problem on the carriage roads with a dog? They need managing rather than avoiding. The roads are around 16 feet wide, so keep your dog to one side on a short lead, announce yourself at blind bends, and give horse-drawn carriages absolute right of way by stepping well off and standing still.

Which carriage road loop has the best bridges? The Amphitheater and Hadlock loop, at roughly 5.4 miles, which crosses the Hemlock Bridge and the Waterfall Bridge above Hadlock Brook Falls. The Duck Brook Bridge, on the Paradise Hill loop, is the most impressive single structure.
