#2: The Inside of Niagara Falls
Niagara Falls is one of the world’s most popular tourist attractions. But, if you’ve never been one of the 13 million annual visitors to this natural wonder, you’ve undoubtedly seen photos of this iconic location. You may think you know what the falls look like, but even if you’ve explored them in person, you’ve probably never seen them like this!

This picture shows the backside of Niagara Falls from inside a tunnel on the Canadian side of the falls. The popular tourist spot is accessible from both sides of the Canadian border, in Ontario and Buffalo, New York. This view is open to the public on a special tour called Journey Behind the Falls.
