Thunder Hole

Thunder Hole is a famous natural rock inlet situated along Ocean Drive in Acadia National Park. As ocean waves crash into the narrow cavern, trapped air escapes with a loud booming sound and dramatic water sprays. Visitors can walk down stone steps to viewing platforms that offer expansive views of the rocky Atlantic shoreline.
