Reversing Falls

The Saint John River creates rapids at its mouth where it meets the Bay of Fundy through a narrow gorge in downtown Saint John.

The indigenous Wolastoqiyik people inhabited this region for thousands of years before European settlers arrived in the 1600s at the river mouth.

The area represents a meeting point between freshwater and saltwater systems, reflected in both Mi'kmaq traditions and scientific research studies.

Visitors can observe the reversal phenomenon from multiple viewing platforms, including Fallsview Park and the Skywalk observation deck above the gorge.

Every 12.4 hours, the Bay of Fundy tides force the river to reverse direction, creating a 4.4-meter waterfall that flows backward.
