Thunder Hole — Acadia
A narrow sea-inlet carved into the granite coastline along Acadia's Park Loop Road, about two miles south of Bar Harbor. When waves enter the slot at mid-tide, compressed air explodes upward with a thunderous boom audible from the parking area. The Park Loop Road — a 27-mile one-way scenic drive — is one of the finest motorcycle roads in the Northeast, and Thunder Hole is its most dramatic single stop. A paved parking area and walkway are accessible directly from the road. Park entry fee applies.
The Park Loop Road is a motorcycle classic — sweeping ocean-cliff curves, carriage roads, and summit access all on one continuous loop. Thunder Hole is the most photogenic stop on the route and has its own parking pull-out; the timing of the boom is best around mid-tide on incoming swells.
