Introduction

Thunder Hole is a cleft in the granite shoreline of Acadia National Park, Maine, where incoming swells compress trapped air and burst out with a thunderous boom — best at mid-tide on a choppy day. Part of Acadia's dramatic Park Loop Road, it pairs the roar with spray, gulls and the scent of spruce. Steps lead down to a viewing ledge; nearby Ocean Path threads toward Sand Beach and Otter Cliff. A short, sensory stop that captures the wild Atlantic edge of New England.
