South Bubble Trail and Bubble Rock – Acadia National Park


South Bubble Trail is a unique hike that offers some of the best views in Acadia National Park. The large boulder featured at the end of this hike was carried by glaciers before resting on the edge of this range – absolutely incredible. Make sure this is on your list of hikes in the park!

Attraction Tips


There is extremely limited parking at this trailhead, so make sure to do this first thing in the morning (before 8am). You can also park at Jordan Pond House and hike from there, but itā€™ll be a bit longer and that parking lot also fills up quickly. Either way ā€“ do this hike early and youā€™ll have it to yourself!


This is one of the best views in the entire park. Make sure to go out of your way to get here!


This trail splits in two about 5-10 minutes in for the North and South Bubble. Make sure to do both ā€“ each offers very unique and picturesque views of the park.

Attraction Details

The parking lot for this hike is very small, so make sure to get here earlier in the day. We tried to do this hike earlier in our trip around lunch, but simply couldnā€™t find a parking spot to do so. That being the case, we decided to make this an early morning activity to make sure that we got a spot and beat the crowds.

To start the hike, simply head up the trail until you reach a sign that splits between the North and South Bubbles – about 5-10 minutes into the hike.

We recommend doing the North Bubble Trail first, but once you’re done with that part, follow the South Bubble Trail (which is a fairly short uphill trek through the woods) until you get to the summit. If you go a bit further, there is a short side trail to the epic Bubble Rock – you can’t miss it! Once you grab some pictures and soak in the view, head on back the way you came back to the car.
