Acadia’s Quieter Summit
Dorr Mountain is the second-highest peak in Acadia National Park, reaching 1,270 feet just east of Cadillac Mountain. While Cadillac draws tens of thousands of visitors to its auto road and sunrise crowds, Dorr offers a more intimate experience. The trails are steeper, more technical, and far less traveled. The views from the summit are nearly identical to Cadillac’s, and on most days you will share the top with only a handful of other hikers.
What sets Dorr apart is its trail system. The mountain is laced with historic stone staircases, iron rungs, and hand-carved granite steps built in the early 1900s by the Bar Harbor Village Improvement Association, much of it engineered by Waldron Bates. These trails are among the finest examples of hand-built trail construction in the eastern United States.
The Trails
There are several routes up Dorr Mountain, each with a different character.
Dorr South Ridge Trail is the most straightforward. Starting from the Otter Creek end of the park, it climbs steadily along the south ridge with open views developing as you gain elevation. This is the most moderate route and the best option for hikers who want the summit without technical challenges. The South Ridge Loop covers about 3.3 miles.
The Dorr Mountain Ladder Trail is the signature route. It climbs the steep east face using a series of iron ladders and carved granite steps bolted into massive boulders. The steep section is roughly 0.4 miles and involves three separate metal ladders. It is exciting, safe for sure-footed hikers, and unlike anything else in the park.
The Gorge Path ascends through the narrow ravine between Dorr and Cadillac. It features over 1,000 stone steps and is one of the most beautiful trail corridors in Acadia. The stonework is remarkable.
The Dorr Mountain Ladder Trail and Precipice Trail may be closed seasonally, typically from mid-March through mid-August, to protect nesting peregrine falcons. Check the Acadia National Park website or visitor center for current closures before planning a hike that uses the ladders.
The Summit
The summit of Dorr is an open granite dome with views in nearly every direction. Cadillac Mountain rises immediately to the west, and you can see hikers and cars on its summit. To the east, Frenchman Bay stretches toward the Schoodic Peninsula with the Porcupine Islands scattered below. To the south, the ocean opens up past Otter Cliffs and the Cranberry Isles.
The summit is exposed and windy. There is no shelter, but the views more than compensate. Bring a layer even on warm days.
For a longer loop, descend from Dorr’s summit west to The Notch between Dorr and Cadillac, then take the Gorge Path down. This gives you both the ridge views and the historic stone staircase in one outing. Total distance is about 4 miles.
When to Go
Spring
Trails may be muddy. Ladder trails often closed for falcon nesting. Wildflowers along the lower paths.
Summer
Full access to all trails. Warm days and long light. Dorr is much quieter than Cadillac even at peak season.
Fall
Foliage in the Gorge Path corridor is exceptional. Clear air gives the longest views. Cooler temps make the climb comfortable.
Winter
South Ridge is hikeable with microspikes. Ladder Trail is slick and not recommended. Shorter days but the summit solitude is unmatched.
Practical Notes
Cell service is good in the Dorr Mountain area. You are close to Bar Harbor and the park’s cell towers. The park entrance fee applies. Parking is available at the Sieur de Monts area and along the Park Loop Road.
Dogs are not allowed on the ladder trails in Acadia. If you want to bring a dog, use the South Ridge Trail and check current park regulations for leash requirements.
Start from the Sieur de Monts parking area for the most direct access to the Ladder Trail and the Gorge Path. This lot fills by mid-morning in summer, so arrive early or take the Island Explorer shuttle. The South Ridge trailhead near Otter Creek is usually less crowded.

FAQ
How does Dorr compare to Cadillac Mountain?
Dorr is 100 feet shorter than Cadillac but feels wilder. There is no auto road, so the summit is far quieter. The views are nearly identical. Dorr's trails are more technical and historic, with stone steps and iron ladders that Cadillac lacks.
Is the Ladder Trail scary?
The iron ladders are solid and well-maintained. The exposure is real but manageable for anyone comfortable with heights. Children who are confident climbers handle it fine. If ladders make you nervous, take the South Ridge Trail instead.
Can I loop Dorr and Cadillac together?
Yes. A popular loop goes up Dorr via the Ladder Trail or South Ridge, across The Notch to Cadillac summit, then down the Cadillac South Ridge. Total distance is about 5 to 6 miles depending on the route.
Are dogs allowed on Dorr Mountain?
Dogs are not allowed on the ladder trails. They are allowed on leash on the South Ridge Trail and some other routes. Check Acadia's current pet regulations before heading out.
When is the best time to hike Dorr?
Late September through mid-October for foliage, clear air, and smaller crowds. Summer is excellent but busier. Avoid the ladder trails from mid-March through mid-August when they may be closed for peregrine falcon nesting.
