With over 20 million people visiting Niagara Falls each year, these waterfalls are undoubtedly among the most stunning natural attractions in the United States. Their thunderous roar, the delicate mist that rises as the water crashes against the rocks, and the sheer power of the falls captivate visitors from around the globe.
However, while Niagara Falls is a breathtaking spectacle in its own right, there are many more places near these three waterfalls that offer an equally amazing experience, especially during the autumn season.
