Trip ideas while visiting Acadia National Park in Maine

Thunder Hole

Witness the mesmerizing beauty of a captivating natural wonder found in this remarkable cave, which is partially submerged underwater. Just a few hours before high tide, the cave comes alive with an incredible display of sound. As the powerful waves rush into the cavern, a resounding boom echoes through the air, reminiscent of a mighty thunderstorm. It is from this awe-inspiring sound that the cave derives its name. Brace yourself for the invigorating spray of water that can reach up to 40 feet in distance. If you prefer to stay dry amidst the excitement, make sure to wear a reliable poncho.

To capture the grand boom, a bit of luck and perfect timing are needed. Recent travelers suggest visiting during the changing tides for the best experience. It’s important to know that people with limited mobility may have difficulty fully participating in this spectacle due to the uneven rocky terrain. But don’t worry, even if you can’t go down, you can still see and hear the majestic crashing waves. If you decide to venture beyond the viewing platform, which has sturdy railings and level steps, be careful because the rocks might be slippery from the spray. Take a moment to admire the awe-inspiring show and enjoy the breathtaking views. In the distance, you’ll glimpse the Schoodic Peninsula, while on the left is the mesmerizing Sand Beach, and to the east, the magnificent Otter Cliff demands attention.
