Thunder Hole Visitors Guide – Acadia National Park

April 4, 2023by Thomas Tash

Thunder Hole is a fascinating natural wonder located in Acadia National Park. It is a must-see attraction for anyone visiting the park. The site is named for the loud roaring sound made by the waves crashing against the rocks, creating a deep thunder-like boom that can be heard from quite a distance.

Getting to Thunder Hole in Acadia National Park

Getting to Thunder Hole is relatively easy, as it is located on the Park Loop Road, the main thoroughfare within the park. Visitors can either drive to the site or take the park’s free Island Explorer shuttle bus. Parking can be limited during peak season, so it is best to arrive early to ensure a spot.

Using the free Island Explorer park shuttle, you’ll want to hop on to the #4 Loop Road bus, which follows along the Park Loop Road and makes stops at many of the most popular sites along the loop, including Sand Beach, Cadillac Mountain, Jordan Pond House, and others.

The main attraction is, of course, the hole itself. This is a small inlet in the rocks where the waves crash in and create a thunderous roar. The sound is caused by a combination of the waves’ force, the shape of the inlet, and the air being forced out of the hole. The sound can be quite loud and can startle visitors, so be prepared.

In addition to the main attraction, there are also public restrooms and a small Thunder Hole gift shop located in the parking area across the road.
