About
The Reversing Falls is a natural phenomenon in Saint John, New Brunswick, where the Saint John River appears to flow backwards. It is also known as the Saint John Reversing Falls Rapids. The effect comes from the extreme tides of the Bay of Fundy: when the incoming tide rises, it pushes against the river's outflow and reverses the current through the rapids, and when the tide falls, the river runs forward again.
What to expect
The best place to watch is Fallsview Park, which overlooks the rapids. From here you can see the water swirl and churn as the tide changes, and the scene shifts over the course of the day. Because the timing depends on the tides, the rapids look different from one visit to the next, so it is worth checking the tide times before you go.
Interpretive displays at the park explain the tidal mechanics behind the reversal, which helps make sense of what you are seeing. Many visitors find the displays a useful starting point before they spend time watching the water.

The Reversing Falls is a good stop for anyone interested in natural science or unusual landscapes. It can be combined with a wider look at Saint John and the surrounding Bay of Fundy coast, which is known for its large tidal range.
