10 Acadia Trails Where Dogs Are Welcome, Ranked by Difficulty

Champlain by the Precipice is closed to dogs. Champlain by the North Ridge is not. Several Acadia summits have two routes with opposite rules, and getting the name wrong is how a hike goes badly.

The most useful thing to understand about hiking Acadia with a dog is that several of the park's famous summits have two routes up, one of which is closed to pets and one of which is not.

Champlain Mountain by the Precipice Trail is closed to dogs. Champlain by the North Ridge Trail is open. Dorr Mountain by the Ladder Trail is closed. Dorr by other routes is not. Beech Cliffs Trail is closed. The Beech Mountain Loop, which reaches the same summit, is open.

Get the name wrong and you either turn back at a sign or, worse, find yourself part-way up a set of iron rungs with a dog that cannot follow.

Ten trails below where dogs are genuinely welcome, ranked easiest to hardest. All require a leash no longer than six feet under Acadia's pet rules. Distances are approximate.

1. Compass Harbor Trail, roughly 0.8 miles

The easiest walk on this list and the closest to town, looping around the site of George B Dorr's old cottage and gardens on the shore just south of Bar Harbor.

Flat, short, wooded, and with shoreline access at the far end. It takes twenty minutes and you can walk to it from town, which makes it the ideal first outing after a long drive.

Best for: senior dogs, puppies, a first evening, or a wet day.

2. Jesup Path, roughly 1 mile

A boardwalk through white birch woods and meadow near Sieur de Monts, running out to the Tarn. Level, soft underfoot, and unusually easy on a dog's feet in a park where granite is the default surface.

Frequently combined with the Hemlock Path to make a loop, which is a good option if you want a little more distance without any more effort.

Best for: arthritic dogs, sore pads, and anyone who wants a walk rather than a hike.

3. Ship Harbor Trail, roughly 1.3 miles

A figure-of-eight loop on the quiet western side of Mount Desert Island, ending at a rocky shore with tide pools at low water. Well-graded, easy footing, and far less busy than anything on the Park Loop Road.

Check a tide table if the tide pools are the point. Discourage your dog from drinking the sea while you are there.

Best for: an easy walk with something to look at, and avoiding crowds.

4. Wonderland Trail, roughly 1.3 miles

Ship Harbor's neighbour and its near-twin. An old road bed out through spruce to a cobble beach, flat the whole way, with tide pools at the end.

The two are close enough together to do both in a morning, which is a good use of a day on the Quietside.

Best for: the same as Ship Harbor, and worth doing back to back with it.

5. Ocean Path, roughly 2.2 miles each way

A packed gravel path running from Sand Beach past Thunder Hole to Otter Point, with the sea on one side and the Park Loop Road on the other.

Easy underfoot for its whole length, which is why it sits in the easy half of this list despite being 4.4 miles round trip. It parallels the road, so you can turn back or arrange a pickup at any point, and the free Island Explorer serves stops along it and takes leashed or crated pets.

Note: Sand Beach itself is closed to pets from 15 June to 8 September. The path is not.

Best for: the classic Acadia coastline with no scrambling.

6. Great Head Trail, roughly 1.4 miles

A loop over the headland at the eastern end of Sand Beach, with open sea views for much of the circuit. Short, but this is where the list stops being flat: there is real granite underfoot and some steeper rocky sections.

No ladders and no rungs, which is the distinction that decides whether a dog can do an Acadia trail.

Best for: a first proper Acadia hike with a sure-footed dog.

7. Beech Mountain Loop, roughly 1.2 miles

A short summit loop on the western side of the island, finishing at a fire tower with views over Long Pond and out to the sea.

Read the name carefully. The Beech Cliffs Trail is closed to pets. The Beech Mountain Loop is not. They start from broadly the same area and reach the same mountain, and they are not the same trail. If you find yourself at the base of a cliff face, you are on the wrong one.

Best for: the best summit-to-effort ratio in Acadia with a dog.

8. Champlain North Ridge Trail, roughly 2 miles with about 862 feet of gain

The dog-legal route up Champlain Mountain, climbing an open granite ridge with expanding views over Frenchman Bay and the Porcupine Islands.

The Precipice Trail, which also climbs Champlain, is closed to pets, and for good reason: it is a near-vertical iron-rung route. The North Ridge gets you to the same summit on your feet.

Open ridge means full sun and wind, so carry water and pick a cool day.

Best for: a genuine mountain with a fit dog, without any of the Precipice's problems.

9. Gorham Mountain Loop, roughly 3.5 miles round trip

A modest summit with excellent coastal views, reached on rock and ledge with no ladder sections. Commonly combined with the Ocean Path into a loop, which is the version most people walk.

One serious warning. Many published Gorham Mountain routes chain it with the Beehive Trail, which is closed to pets and is an iron-rung climb. If a route description mentions the Beehive, it is not a dog route. Take Gorham out and back, or loop it with the Ocean Path instead.

Best for: a half day with a fit dog, and the best coastal views on any dog-legal summit.

10. Cadillac North Ridge Trail, roughly 4.4 miles round trip

The hardest on this list, and the biggest reward: a long open granite ridge to the summit of Cadillac Mountain, the highest point on the eastern seaboard.

Avoid the Cadillac Mountain west face trail, which the Park Service lists as not recommended for pets. The North Ridge is the dog route.

Fully exposed for most of its length, with no shade and no water. Not a hot-day hike, and not a first-day hike for a dog straight off a long drive.

If your dog cannot do it, the summit road is open to vehicles with a dog aboard, though vehicle reservations are required in season.

The six trails that are closed to dogs, in one place

Worth committing to memory, because every one of them is a route a guidebook may recommend.

Precipice Trail. Beehive Trail. Ladder Trail to Dorr Mountain. Beech Cliffs Trail. Perpendicular Trail on Mansell Mountain. Jordan Cliffs Trail, between the Penobscot East Trail and the carriage road.

All six involve iron rungs, ladders, or exposed cliff edges. The prohibition protects your dog and also the people below you on the ladder.

And the ten that are legal but not recommended

A separate Park Service list, and the one visitors skip. Acadia Mountain, Flying Mountain, Giant Slide, Cadillac Mountain west face, the Bubble and Jordan Ponds Path, Norumbega Goat Trail, Bubbles-Pemetic Trail, Penobscot Mountain Spring Trail, Upper Beachcroft Trail, and Upper Gorge Trail.

Nobody will stop you. You may simply find you cannot get a large dog back down a granite slab. The full list of closures and warnings is published by the park itself on Acadia's pet page, and it is worth reading once before you pick a trail.

The alternative when the trails are wrong

On a wet day, with a heavy dog, with an older dog, or when you simply want distance, the answer in Acadia is always the same: the carriage roads.

Forty-five miles of car-free, gently graded, packed-gravel road, open to leashed dogs on every mile, with no ladders and nothing to lift a dog over. For an older dog especially, this is the surface to build a day on: traveling with a senior dog covers how to judge the distance.

Practical notes for hiking Acadia with a dog

Wet granite is slick. Acadia's rock grows a thin film in damp shaded sections and holds water for a long time after rain. Dogs grip it poorly. Maine fog is frequent. On a wet day take Jesup Path, Ocean Path, or the carriage roads.

Carry water. Most of Acadia's lakes are public water supplies and closed to pets year round, so there is far less drinking water available than the map implies.

Check for ticks after every walk. Maine has a substantial tick population, nymphs peak in late spring and early summer, and adults become active again in autumn. Discuss prevention with your veterinarian before the trip.

Parking is the real constraint. Sand Beach, Jordan Pond, and the Bubbles fill early. The fare-free Island Explorer takes well-behaved leashed or crated pets, though not on the seats.

Save a vet number. Mount Desert Island has limited after-hours veterinary coverage. See emergency vet, what to know.

Come in September if you can. The Park Service closes Sand Beach to pets from 15 June to 8 September and Echo Lake from 15 May to 15 September, so both reopen to dogs as the crowds thin. Early autumn is the single best planning decision available here.

If you have not booked, search the PetCompass hotel directory, or filter straight to hotels that allow large dogs if yours is big. What to pack for a hotel stay with a dog covers the kit for a trail-heavy trip.

Conclusion

Acadia gives a dog roughly 100 miles of trail, which is more than almost any other national park allows, and the ten above are the ones worth planning a trip around.

The pattern to remember is the one at the top. Champlain, Dorr, Beech, and Cadillac all have a dog-legal route and a dog-prohibited or not-recommended route to the same summit. Champlain North Ridge, not the Precipice. Beech Mountain Loop, not Beech Cliffs. Cadillac North Ridge, not the west face. And never chain Gorham Mountain with the Beehive.

Start with Compass Harbor and Jesup Path. Work up through Ship Harbor and Wonderland. Take Great Head or Beech Mountain for a first summit. Save Cadillac North Ridge for a cool day and a conditioned dog.

Trail conditions, closures, seasonal dates, and vehicle reservation requirements change. Confirm current details with the National Park Service before you go. Then find the trail your pet will wag "yes" to.

Frequently asked questions

Which Acadia trails allow dogs? Roughly 100 miles of trail are open to leashed dogs, including Compass Harbor, Jesup Path, Ship Harbor, Wonderland, Ocean Path, Great Head, the Beech Mountain Loop, Champlain North Ridge, Gorham Mountain, and Cadillac North Ridge. Leashes must be no longer than six feet.

What is the easiest dog-friendly hike in Acadia? Compass Harbor Trail, at roughly 0.8 miles, flat and wooded with shoreline access, just south of Bar Harbor. Jesup Path is a close second and is a boardwalk, which is the kindest surface in the park for sore pads.

Can I climb Cadillac Mountain with my dog? Yes, by the North Ridge Trail, roughly 4.4 miles round trip on open granite with no shade or water. Avoid the Cadillac Mountain west face trail, which the Park Service lists as not recommended for pets. The summit road is also open to vehicles, with reservations required in season.

Is the Beehive Trail dog friendly? No. The Beehive is one of six Acadia trails closed to pets, along with the Precipice, the Ladder Trail to Dorr Mountain, Beech Cliffs, Perpendicular on Mansell Mountain, and part of the Jordan Cliffs Trail. All involve iron rungs or exposed cliff edges.

Can I hike Champlain Mountain with a dog? Yes, by the Champlain North Ridge Trail, roughly 2 miles with about 862 feet of gain on an open granite ridge. The Precipice Trail reaches the same summit and is closed to pets.

What should I do in Acadia with a dog on a rainy day? Take the carriage roads, Jesup Path, or Ocean Path. Acadia's granite grows a thin film when damp and holds water long after rain, and dogs grip it poorly. Packed gravel and boardwalk are unaffected.
