“A short path that splits Acadia’s iconic “Bubbles” and has the easiest access to famed Bubble Rock.”— David Onkst
Please note, however, you can’t technically get to Bubble Rock directly from this trail. Nevertheless, this path does simply intersect with the Bubbles Trail, and that combined route is your easiest and most direct access to the boulder. Of the two main ways to Bubble Rock via the Bubbles Trail, the northern approach from the northern part of the South Bubble is the gentler of the two, while the southern part of Bubble Trail, which is accessed from the Jordan Pond Path at the southern base of the mountain, connects to the summit in a much steeper manner.
The best place to park to access this trail is at the small Bubble Rock parking lot on the west side of the Park Loop Road located between Pemetic Mountain and The Bubbles. The free Island Explorer bus also drops off there, should you want to forego the car.
This trail starts off from its eastern end by contouring across the northeastern side of the South Bubble for 0.2 miles. It then climbs up through the saddle between The Bubbles for another 0.1 miles, where it then links up with the southern part of the Bubbles Trail. For those who don’t want to view Bubble Rock, just continue on the Bubbles Divide Trail, but for those who want to see the giant boulder, turn southward on the Bubbles Trail and then climb for approximately another 0.3 miles to the summit at 768 feet. Bubble Rock is located slightly downhill on the eastern side of the mountain. Be sure to also go to the southern half of summit to check out the spectacular view of Jordan Pond, arguably, Acadia’s most well-known and picturesque body of water.
Once you’ve finished at the summit, you can either retrace your steps and return to parking lot, or, if you want to continue on and do the entire Bubbles Divide Trail, you should turn westward when you get back to the saddle and proceed down the mountainside until you run into the Jordan Pond Path at the very northern end of the pond. The elevation change is much more significant when you head down the western part of this trail, with the contours stacked up very closely for about 0.2 miles. It does, however, get much more gradual in the last 0.1 miles. Obviously, you can approach this trail from either end, but most people come at it from the east, from the Bubble Rock parking lot. Both trailheads begin in well-forested areas until they get closer to the summit and hit the rocky, exposed, section of the trail.
Overall, this trail can get a bit crowded in the summer months, but it’s still a fun adventure for those who want to take the easiest route up the South Bubble to see Bubble Rock. Climbing this intermediate trail and checking out the famous giant boulder can provide some great memories.
