Thunder Hole
Bar Harbor
Thunder Hole is a famous natural granite inlet along Acadia National Park's Park Loop Road, known for surging ocean waves crashing into a rocky crevice. When water hits the cavern, it forces air and water out to create massive splashes accompanied by a loud, thunderous boom. Visitors can safely watch and hear the powerful roar of the ocean from a dedicated pedestrian walkway.
Commenters express deep nostalgia and affection for trips along the Maine coast, sharing fond memories of family journeys and scenic milestones. Discussion frequently centers on trip logistics, such as high accommodation costs, accessibility for non-hikers, navigation tips, and route recommendations.
- Time your visit around high tide to catch the loudest booms and largest water splashes
- View the crashing waves safely from the installed pedestrian walkway along the rocky shore
- Plan your driving route carefully along Park Loop Road to avoid unnecessary loops
