Drive to the lighthouse from Bar Harbor, Maine. Just a short walk down to the rocky coast.
The lighthouse itself is closed to the public. The rocks can be slippery and dangerous to walk on when wet. Watch out for occasion splash from the wave.
I was taking sunset shots of the lighthouse by the Acadia shore and a flash of light on the wet rocks caught my eye. I found out it was the reflection of the lighthouse in a pool of seawater splashed over the rocks. I waited patiently until the ripples died down and the lighthouse light spun around to take this shot.
