Hiking the Bar Island Loop Trail in Acadia National Park
Distance: 2.2 miles / 3.5 km
The Bar Island Loop Trail in Acadia National Park is a quiet, lesser-known day hike around the most remote parts of Bar Island, compared to the much more popular Bar Island Trail that leads to the summit.
This is because the loop around Bar Island is not a designated or maintained trail, which is why it’s referred to as a 'social trail,' meaning a trail that is created over time through popularity and rarely, if ever, sees maintenance from the National Park Service. Some examples elsewhere include the Billings Gap Overlook in Petrified Forest and the Delta Lake Trail in Grand Teton National Park.
That being said, the Bar Island Loop Trail is a relatively easy adventure for having the designation 'social trail,' as its short distance and proximity to the popular Bar Island Land Bridge and Trail make it more frequently trafficked compared to others in the National Park system that see far fewer hikers, like the South Ariel Peak Trail in Zion National Park.

How to Get to Bar Island in Acadia National Park?
Bar Island in Acadia National Park is an adventure unique to Bar Harbor, Maine, as the trail is only accessible by way of a land bridge that emerges for only a few hours each day on either side of low tide.
This means that to visit Bar Island and hike the Bar Island Trail or Bar Island Loop Trail, visitors must arrive just before or at low tide, in order to make it back to Bar Harbor safely before the tide returns.
Typically speaking, there is only one low tide during the day, with the other occurring during the overnight hours, which is why it’s important to expect the Bar Harbor Land Bridge and Trail to be very busy, as everyone interested in making it to the island will be visiting during the same short window at low tide.
Bar Island Trailhead Parking
Parking for the Bar Island Land Bridge is very unconventional compared to other adventures in Acadia National Park because the National Park Service does not have an official parking lot.
Therefore, the only option is to utilize the paid parking areas throughout Bar Harbor and walk to Bridge Street from there. My advice is to park next to somewhere you’re interested in eating after, allowing your paid parking spot to work for both!

Hiking Checklist - Acadia
Here is a complete list of must-have things that you will want for any hike in Acadia National Park.
Walking to the Trailhead
Regardless of where you park, the walk to Bar Island begins on Bridge Street, a small side street that leads to the water on the north side of Bar Harbor.
Google Maps Directions: Bridge Street
Hiking the Bar Island Loop Trail
At the very far end of Bridge Street, the pavement ends where the land bridge begins.
Before hiking, I highly recommend reading the signs to fully understand how the tides work and what it means to get stranded on Bar Island.
Yes, this has happened many times before, and visitors have spent the night on Bar Island!
Bar Island Land Bridge
This is the beginning of the Bar Island Land Bridge.
When planning your hike, be sure to check the Bar Harbor tide chart linked below, so that you plan to arrive at least one, if not two, hours before low tide to begin hiking when you have the most amount of time to explore the island.
Tide Forecast: Bar Harbor Tide Chart
From the end of Bridge Street to Bar Island, the land bridge only measures about 0.4 miles (0.6 km), and although it is 'technically' drivable, I recommend against it.
Vehicles get stuck in the mud every year and often become a total loss once the tide comes back in. You can see this exact thing happen in the spring of 2022.
That being said, a 0.4-mile (0.6 km) walk simply isn’t worth the drive or the risk. Just park in Bar Harbor to be safe!
Bar Island (Acadia National Park)
Once on Bar Island, Acadia National Park begins, meaning all park regulations, including the no-drone policy, are in effect.
Bar Island Trail
Past the trailhead shown above, the trail on Bar Island follows an easy, gradual path up to the summit, about 0.5 miles (0.8 km) away, with both junctions for the Bar Island Loop Trail located within the first 0.1 miles (0.2 km).
Lower Bar Island-Bar Island Loop Junction
Not long after beginning the hike on Bar Island, the trail to the summit passes by the first of two different junctions with the Bar Island Loop Trail.
That said, I personally prefer to take the second junction up the hill, which is the direction this article is written.
Upper Bar Island-Bar Island Loop Junction
Shortly after the first junction, the Bar Island Loop Trail branches off for the second time.
This is the direction that I like to hike the Bar Island Loop because it ends closer to the trailhead and the land bridge.
All this to say: go right at this split to begin the Bar Island Loop Trail.

Bar Island Loop Trail
Once on the Bar Island Loop, the trail heads directly to the shoreline and follows the perimeter around Bar Island for roughly 1.2 miles (1.9 km) until it returns to the Bar Island Trail at the lower junction.
Even the fall colors on Bar Island are just as good as places elsewhere throughout Acadia!
Jack Perkins House
These ruins on Bar Island are remnants of the people who once called this place home.
For more than 100 years, people lived on Bar Island and even raised sheep until the majority of the land became a part of Acadia National Park in 1986.
Following this, the remainder of the land was purchased in 2003, when the National Park Service acquired this 12-acre property from the TV journalist Jack Perkins, hence the name Jack Perkins House.
After the ruins, go left, and then right to continue around the Bar Island Loop Trail.
This is where the loop continues to the right.
That said, the trail to the left simply leads back to the maintained Bar Island Trail, which leads to the summit.
Past the Jack Perkins House on the south side of Bar Island, the Bar Island Loop noticeably becomes less trafficked.
However, the trail is by no means a difficult hike; it just takes a little more directional awareness to stay on the unmaintained path, as far fewer hikers explore the loop compared to the summit trail.
This is the far eastern end of Bar Island, looking to the east toward Bar Ledge and Sheep Porcupine Island.
On the northern half of Bar Island, the trail becomes even more faint than before.
However, if you ever feel off track, I suggest walking back to a more obvious area, as the Bar Island Loop is fairly easy to regain, since it simply parallels the water.
On the far northwestern side of the island, the Bar Island Loop makes this hard left turn, which can be easy to miss, as it’s not uncommon for some hikers to go straight out toward the point.
Lower Bar Island-Bar Island Loop Junction
Overall, the Bar Island Loop Trail is a fairly easy, straightforward adventure that can be completed alongside the Bar Island Trail to the summit, so long as you are consciously aware of the window surrounding low tide.
That said, both the Bar Island Trail to the summit and the Bar Island Loop Trail combine for a total of 3.0 miles (4.8 km), which is why I feel that both trails are most practical for hikers who can move at a good pace in order to make it back across the land bridge safely.
