Maine is full of some pretty surprising and spectacular natural views and action. No matter where you travel to in the State of Maine you are bound to find something that is naturally occurring that will take your breath away, whether it be the pristine forest and waters of the Allagash, the rugged cliffs overlooking the Atlantic at Acadia, or views from atop the highest point on Mount Katahdin.

One spectacular thing to see is Maine's many reversing falls. There are several spots where you can witness this cool natural anomaly.

What are reversing falls?

The University of Maine has a great webpage full of information about Maine's reversing falls and states that reversing falls are a rare phenomenon that occurs at inlets where freshwater meets the ocean. They are also called 'tidal falls' and occur when the tides change during a day. Water from the ocean will start flowing into the inlet of a river creating a backflow of water that changes the flow of the river. What's key is that there is a narrow passage where the ocean water meets the freshwater of a river.

Another interesting thing about reversing falls is they are unique to Maine along the East Coast of the United States.
