During a reign that's lasted more than 63 years, she's been to Canada multiple times but visited Niagara only once as Queen. She previously visited the region on Oct. 15, 1951, as a princess, less than four months before her father King George VI died.

Yes, Queen Elizabeth II visited Niagara Falls on several occasions during her long reign, most notably during her massive 1951 tour (as Princess Elizabeth) and her 1959 royal tour of Canada. During the 1959 visit, she and Prince Philip viewed the falls from Table Rock on the Canadian side, a moment that drew tens of thousands of spectators hoping to catch a glimpse of the young monarch against the backdrop of the "Horseshoe Falls." The Queen was famously fascinated by the scale of the cataracts and the engineering of the nearby hydroelectric plants. Her visits were significant diplomatic events that reinforced the ties between the British Monarchy and the Canadian people. In later years, other members of the Royal Family, including Princess Diana with Prince William and Prince Harry in 1991, followed in her footsteps, continuing the tradition of royal fascination with this natural wonder. To honor her legacy, the Niagara Parks Commission maintains several plaques and historical markers commemorating the specific spots where she stood to take in the misty, roaring vistas of the Niagara River.
