Bubbles Trail

Bubbles Trail is a 1.5-mile out-and-back from Bubbles Divide parking, with short spurs to North Bubble, South Bubble and Bubble Rock. Allow 60–90 minutes. It is one of Acadia’s best short hikes if you want open granite, a big Jordan Pond view and the park’s famous balanced boulder without giving up half a day. The total includes the walk back and both summit detours.

Bubbles Divide climbs through forest from the lot and gets steeper near the North Bubble junction, where broad steps help with the pitch. Turn right for the summit spur. The trees give way to open granite ledges and a wide view over Jordan Pond, Pemetic and Sargent Mountains, with the Cranberry Isles on clear days. The exposed rock is slick when wet. Return to the junction before continuing; this order lets you visit the north summit without missing the South Bubble route.

From the junction, keep along Bubbles Divide toward South Bubble. The path stays wooded for stretches, then climbs over rougher rock to the open summit, with Jordan Pond spread out to the south. Retrace to the blue-blazed spur for Bubble Rock, the huge white boulder perched near the edge. It is the hike’s signature stop: frame the boulder with the pond below, but stay back from the exposed edge. Afterward, retrace the same route to the parking lot. Continuing down the steep South Bubble face to Jordan Pond is a different, more strenuous route.

The rounded, lopsided hills are pink granite. Glaciers smoothed their northern sides and quarried their southern faces, leaving the rougher, steeper rock you notice on the hike. Seen from the south end of Jordan Pond, their twin outlines look like bubbles. Bubble Rock is a white-granite glacial erratic carried from near Dedham, Maine, and left here as the ice retreated. Its pale stone stands out against the pink granite beneath it.

Start at Bubbles Divide parking on Park Loop Road. The small lot often fills by mid-morning in busy months, so have a backup plan. The Island Explorer lists seasonal service to the Bubbles from mid-June through October; check its current route and stop before relying on the bus. A park entrance pass is required year-round; there is no separate activity fee or trail reservation. Dogs are allowed on leashes no longer than six feet. There are no restrooms at the trailhead.

You can skip North Bubble and walk to South Bubble and Bubble Rock instead, about 1 mile round trip from the same lot. That shorter route still reaches the boulder, but leaves out the north summit and its broader panorama. Both versions have uneven footing, stairs and short, steep sections; this is not an accessible trail, and grippy shoes help on the granite.
