From the Niagara Falls Review:
With Valentine’s Day fast approaching, it’s an appropriate time to recall Niagara Falls’ lengthy and prominent role in the world of love and romance — a role especially renowned due to the city’s fame as a honeymoon destination.
The tradition of newlyweds coming to Niagara began, it appears, in the late 1830s. One piece of evidence to support this dating is a popular song of 1841.
The first verse goes like this:
Oh the lovers come a thousand miles,
They leave their home and mother;
Yet when they reach Niagara Falls,
They only see each other.
By the 1880s a honeymoon at Niagara Falls was a firmly established custom that continued to grow, reaching a peak in popularity between the 1920s and the 1950s. For many, Niagara Falls is still the Honeymoon Capital.
