How does it happen and just what is it? Read on!

The strange phenomenon of Reversing Falls in Pembroke, Maine might at first seem like magic, but in reality it’s just a case of science being pretty incredible.

You probably already know that Maine has one of the most dramatic tidal changes in the country. And, one of the best places to see it in action is in Pembroke Falls State Park.

The tide here rises about 20 feet every 6.5 hours. This incredible change means that water rushes in and out of Dennys and Whiting Bays. This water is sent through the small area between Mahar Point and Falls Island which creates something truly incredible.

It actually appears to be a waterfall running opposite to the existing current. The phenomenon is known as Cobscook Falls, or just “The Reversing Falls.”

What you can’t see is the large rock ledge that makes it impossible for water to move smoothly. And so, when the tide comes in, a mighty force is playing out underwater. This activity creates a waterfall effect with whirlpools and fascinating swells.

And that’s not all. The outgoing tide presents the real mystery.

As the tide rushes in the opposite direction, the water moves over this rocky ledge in a reverse direction. This causes what appears to be a waterfall going against the current. What’s also interesting is how calm the water looks when the tide is still. It’s as if nothing notable is happening. Unless you’re in the right place at the right time!

While the ares is wonderful on a warm day, you’re not allowed to swim here. The water can make for dangerous conditions. Boat travel should also be avoided unless with a knowledgeable and local guide.
