Runner Notes

You can run this trail, but it might be a bit crowded with people during the summertime. If you run it from the east, the climb is much more gradual than from the Jordan Pond end of the path. Parts of the path can be quite steep, so plan accordingly.


Although this trail is short, it can provide a great deal of fun, particularly for families. 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 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.
