Reversing Falls Park is located in Maine

Reversing Falls Park is a municipal park in Pembroke, Maine. It is located at Mahar Point, the northern point of a narrows separating Dennys Bay from Cobscook Bay in far eastern Maine. The narrows are subject to a reversal of current twice a day, owing to the area's unusually high tides. In addition to viewing this action, the park is also well suited for wildlife viewing.
