One of the more popular falls in New Brunswick and common tourist destination is the Reversing Falls located in the coastal city of Saint John. The falls appear as rapids, and arise as the Saint John River meets and the tidal waters of the Bay of Fundy. The tidal effect creates a strong current, which has historically blocked access to the Saint John river — restricting travel to times of the reversal of water at high and low tide.

To see the falls, head to Saint John. Take the Reversing Falls exit from Highway 1 at exit 119A from the west or exit 121 Chesley Drive from the east. Continue on Chesley to the Reversing Falls Bridge and parking area. Jet boat rides are available in the summer months. Photos can also be taken from the west side of the bridge near the entrance to the Irving Pulp and Paper mill.
