One of the world’s most famous natural attractions, the great arcs of hissing, frothing water crashing over cliffs 20 stories high is a dazzling spectacle. Drifting spray adds to the excitement of being near the edge of a stomach-churning drop. The 173-ft- (53-m-) high Canadian Horseshoe Falls is the mightiest of the three cataracts that make up Niagara Falls. Across the Niagara River is the impressive American Falls, including the smaller Bridal Veil Falls. When visiting the falls, be sure to make time to stop at some of the other sights in the Niagara region, including its renowned vineyards and historic museums.
