Bubbles Trail

The Bubbles Trail dishes out classic Acadia scenery in a compact package: two quick summits, sweeping views over Jordan Pond and Eagle Lake, and the famous glacial erratic, Bubble Rock. Most hikers do this as a short lollipop starting at the Bubbles Divide trailhead on Park Loop Road, using Bubbles Divide to reach spurs for North Bubble and South Bubble. Expect roughly 1.5–1.7 miles total for the classic both-summits outing (your length here includes the Bubbles Divide connector).

Route and options

From the Bubbles Divide parking lot, head up Bubbles Divide. In about 0.1 miles you'll pass the Jordan Pond Carry junction (useful if you want to link to Jordan Pond Path or Eagle Lake Trail). Continue to the Bubbles Trail junction (about 0.25 miles from the lot). Many hikers tag North Bubble first for a slightly friendlier ascent, then traverse to South Bubble and take the short spur to Bubble Rock before returning via Bubbles Divide. If you’re crowd-averse or just energized, continue north to Conners Nubble and loops around Eagle Lake for a longer, quieter day.

What you’ll see

Both summits open onto granite ledges with big, photogenic sightlines: Jordan Pond right below, Eagle Lake beyond, with Pemetic and Penobscot Mountains framing the scene—and even ocean peeks toward Seal Harbor on clear days. Bubble Rock, a massive perched boulder on South Bubble’s cliff edge, is a textbook glacial erratic transported here by ice over 10,000 years ago. The geology is the star: glacier-sculpted granite domes, ledges, and erratics.

Difficulty and footing

Short doesn’t mean flat. You’ll tackle several steep pitches, stone steps, and brief rocky scrambles—hands may come out near the summits. The open granite is excellent for views but turns slick when wet and can be hazardous with ice; traction is recommended in winter. North Bubble tends to feel a touch stiffer on the climb, but both are manageable for fit beginners and families comfortable with uneven terrain.

Logistics and crowds

Parking is at the Bubbles Divide lot on Park Loop Road, which fills fast in peak season—arrive early or late. There are no bathrooms at the trailhead; the nearest restrooms are at Jordan Pond House about two miles south. Dogs must be leashed; still, the steep southern approach to South Bubble isn’t great for many pups. Wayfinding is straightforward with good signage; carry a map if you plan to link farther afield via Jordan Pond Carry.

Best time to hike

Late spring through fall delivers the best footing and clearest views, with fall foliage adding extra drama. Mornings beat the crowds and give soft light on Jordan Pond; late-day light is also lovely, but parking can be tougher. The trail is open year-round, but in winter expect ice on the ledges—microspikes or similar traction are strongly advised.
