The Bay of Fundy is a highlight of some cruises to Canada from Boston. Saint John, New Brunswick, is the gateway port for the Bay and is included on 7-day and 14-day round-trip cruises. See the schedule below.
The Bay of Fundy is a natural wonder. It is 180 miles long and the depth is 400 to 700 feet. The thing that makes it exceptional is the tide. Tides in the Bay are considered the highest in the world. The water rises and falls by as much as 50 feet! The funnel shape of the bay contributes to the extreme tidal effect.
This short video explains the science behind it all.
