Saint John is a city on the Bay of Fundy, in New Brunswick, Canada. It’s known for the Reversing Rapids, a phenomenon caused by bay tides colliding with the Saint John River. Food and craft stalls fill the Saint John City Market, in an 1876 building. On a peninsula nearby, trails wind through Irving Nature Park’s salt marshes, volcanic rock and forests. The 1913 Imperial Theatre stages plays, concerts and dance.
