Fallsview Park is one of the best locations to view the Reversing Falls Rapids, a daily phenomenon created by the collision of the Bay of Fundy tide and the St. John River. Get a bird’s eye view on the river’s turmoil at the Saint John Adventures Zipline – an adrenaline-pumping course that is a safe but exciting way to see this natural wonder – or take a sightseeing cruise and explore the Stonehammer Geopark.
