Hiking the Day Mountain Trail in Acadia National Park
Distance: 0.8 - 2.5 miles / 1.3 - 4.0 km
The Day Mountain Trail in Acadia National Park is one of the park’s easier summits, much like the nearby Triad Trail or Flying Mountain near Southwest Harbor.
I say this because whether you decide to hike from the north or south, Day Mountain is one of the quicker day hikes, offering a number of beautiful viewpoints across Mount Desert Island throughout the trail.
On top of this, I personally see Day Mountain as a hidden gem because, unlike taller summits like Penobscot, Sargent, and Pemetic Mountain, Day Mountain’s lower elevation makes it a much better day hike for enjoying the fall colors. This cannot be said about the taller summits just mentioned, as they often climb too high and too far away from the most beautiful pockets of trees.
This is all to say that yes, there is a sweet spot for enjoying fall colors in the Northeast, and Day Mountain sits at the perfect elevation to enjoy the beautiful views and beautiful fall colors in just one adventure!
Day Mountain Trailhead Parking
Parking for Day Mountain is located at one of two places, depending on whether you decide to hike from the north or the south.
First, there is the much more popular and larger parking lot at the southern trailhead off Champlain Road, or there is a smaller parking area alongside Park Loop Road at the northern trailhead. This hopefully helps explain why the distance can be so variable, which includes the Day Mountain Carriage Road in the longest 2.5-mile (4.0 km) total.
In any case, remember to purchase your National Park pass in advance and display your pass or entrance receipt here and at every trailhead in Acadia National Park, whether you went through an official entrance station or not. Yes, law enforcement officers check parked cars throughout Acadia, and I have seen tickets handed out to vehicles not following the rules of a U.S. fee area.
On a different note, be aware that Acadia National Park is one of the busiest parks in the country, and finding a place to park, even at less-known trailheads, can be incredibly challenging during the busiest times of the year.

Hiking Checklist - Acadia
Here is a complete list of must-have things that you will want for any hike in Acadia National Park.
Hiking the Day Mountain Trail
Personally, I like to begin the hike up Day Mountain at the southern trailhead because I enjoy taking the Day Mountain Trail up to the summit and the Day Mountain Carriage Road back down, as it allows for different viewpoints along each route.
Regarding my thoughts above, the article is about the Day Mountain Trail, beginning from the southern trailhead.
Day Mountain-Carriage Road Junction
After just 0.2 miles (0.3 km), the Day Mountain Trail meets the junction for the Carriage Roads that both loop around Day Mountain and climb to the summit, beginning here at this three-way split.
That being said, go straight up the Day Mountain Carriage Road that climbs the mountain, and look for the continuation of the Day Mountain Trail on the left-hand side shortly after the intersection.
This is where the Day Mountain Trail branches off to the left from the Carriage Road that climbs to the summit.
After leaving the Carriage Road, the Day Mountain Trail begins a slow, gradual climb of roughly 260 ft. (79 m) to the summit.
Day Mountain-Carriage Road Junction
This is the second Day Mountain Carriage Road junction, with just one more before the Day Mountain Trail reaches the summit.
Between the second Carriage Road crossing and the third, the views on both sides of the trail begin to open up!
This is why Day Mountain can make for a great sunrise and sunset hike when enjoyed from this area along the trail!
Day Mountain-Carriage Road Junction
This is the third and final time the Day Mountain Trail crosses the Carriage Road before the summit.
That said, go straight once more to reach the top, located about 0.2 miles (0.3 km) away.
When the Day Mountain Trail reaches the loop at the top of the Carriage Road, the summit can be found straight ahead.
Day Mountain
According to the National Park Service, the summit of Day Mountain stands at approximately 574 ft. (175 m).
However, in my opinion, the summit isn’t the best place for views on Day Mountain, as the views get significantly more beautiful on the hike down the Carriage Road—should you decide to follow the same route I recommend.
Walking Down the Carriage Road
While it’s not necessary—and certainly longer by about 0.7 miles (1.1 km)—to descend Day Mountain via the Carriage Road, I recommend walking it down because there are a handful of unique viewpoints that can’t be seen from the trail.
In summary, the Day Mountain Carriage Road back to the original split totals 1.4 miles (2.3 km), while the trail itself measures only 0.7 miles (1.1 km).
Carriage Road-North Day Mountain Junction
Almost immediately after leaving the summit, the Day Mountain Carriage Road passes by the North Day Mountain Trail, the shorter, but also steeper, of the two routes to the top.
There aren’t too many places to see the fall colors on the Day Mountain Trail itself, but the views looking out toward the lower elevations are truly second to none if you visit Acadia at the right time of the year.
To learn more about how to time the fall colors, I highly recommend checking out the fall foliage map linked below, as peak season on the coast tends to be a bit later than areas further inland.
