Located on the Bay of Fundy, Saint John has a vibrant arts centre, quality dining and shopping, pristine parks and history lined streets. One of the city's biggest attractions is the reversing falls of the Saint John river whereby the Bay of Fundy causes the river flow to reverse. The city is also home to Martello Tower, a harbour fortification built during the war of 1812 and Fort Howe with its excellent views over the port.
