Something amazing happens when the highest tides in the world arrive in Saint John, New Brunswick. Twice a day, tides in Canada's Bay of Fundy rise as high as 56 feet in places – the height of a 5-storey building! In Saint John, New Brunswick, the St. John River drains into the Bay of Fundy. When the Bay of Fundy tides rise and fall, 100-billion tons of water … a volume equal to ALL of the world’s rivers … enters and exits the bay. And that's when things get interesting in Saint John.

Saint John was a port of call on our ultra luxury Seabourn cruise of Canada and New England, so BestTrip.TV cameras were in the right place at the right time – on Saint John's new, glass-floored Skywalk. Watch this video to share our bird's eye view directly over the gorge carved through billion-year-old rocks – to see the epic Bay of Fundy tides reversing the direction of the river flow. You just can't miss the Reversing Falls Rapids seen from Saint John's Skywalk.
