Distance: 1.5 miles round trip

Terrain: Forested path, steep rocky sections, exposed granite, wide stairs

Hike Description

The hike starts at the Bubbles Divide parking lot.

Follow the Bubbles Divide Trail for .25 miles as it becomes steeper with steps just before the junction of the Bubbles Trail to North Bubble.

Continuing onto North Bubble, the trail becomes steep with open granite ledges and will be slick in wet weather. There are excellent views of Jordan Pond, Pemetic and Sargent Mountains, and the Cranberry Isles.

Return back down from the summit of North Bubble to the first junction. Turn right and follow the Bubbles Divide Trail towards South Bubble and Bubble Rock for .7 miles.

After reaching the summit of South Bubble, turn back and follow blue blazes for Bubble Rock, a precarious glacial erratic.

Return on the Bubbles Divide Trail all the way back to the parking lot.

Turn left onto the carriage road and continue for .6 miles.

Look for a path and small wooden footbridge. When Jordan Pond Carry trail intersects the carriage road, turn right onto it. Portions of the trail have wooden planks to avoid wet sections.

The trail gently rises until it reaches the junction with the Bubbles Divide Trail. Turn left and return to the parking lot.

Hike Double Bubble Nubble Loop with Island Explorer the Park Service's write-up

4-5 Hours · dogs allowed · Spring, Summer, Fall

The Double Bubble Nubble is fun to say and fun to do for anyone looking for a longer (6.6 mile) hike filled with short but steep climbs up three peaks with stunning views of Jordan Pond and Eagle Lake in the valley below. This hike is mostly moderate with a few areas of intense rock scramble.

The Bubbles are an extremely worthwhile hike in Acadia National Park for their scenic and iconic value. Combining these two summits with Conners Nubble will give hikers an exciting 6.6-mile trek with numerous, breathtaking vistas. The bus has the advantage of dropping hikers a mile away from the formal start of the loop, an inaccessible location to vehicles.

For a short distance (0.4 miles) hikers will walk along the mixed-use Carriage Roads before connecting to flat and gradual hiking trails weaving south towards Jordan Pond along the Jordan Pond Carry. Hikers have a choice when it comes to summiting South Bubble and summiting is not necessary to complete the loop if hikers want to skip it all together. The steepest and most strenuous trail entails more than 450 feet of climb over 0.2 miles. Hikers will need use of their hands in places over intense but brief rock scramble. For this reason, the southern ridge along the Bubbles Trail up South Bubble is not recommended for dogs.

The summit of South Bubble overlooks Jordan Pond and Eagle Lake, and the glacier erratic, Bubble Rock, is a worthwhile, 0.1-mile side trip off the summit to see this large boulder teetering on the edge. The northern decent is a more gradual trail and an alternative out and back summit for anyone looking to avoid extreme rock scramble.

The continuation of the Bubbles Trail up the North Bubble is comparatively more moderate, and the summit gives views over Eagle Lake, typically with far fewer people. Continuing north to Conner’s Nubble will thin the crowds further and the summit offers yet another scenic overlook of Eagle Lake before the trail loops back around to its starting point.

Accessibility Periods of rock scramble make this trail briefly strenuous and its distance a challenge. Hikers should expect many rocks and roots throughout the trail and should be prepared to use their hands for balance when summiting. The trail gains elevation quickly in three distinct places as it summits both Bubbles and Conners Nubble so hikers will need climbing energy throughout the hike.
