If you think the Falls put on a show by day, wait until you see Niagara Falls at night. Niagara Falls' nightly illuminations transform the water wonder into a kaleidoscopic. Niagara Falls is in a public location on Niagara Parks land. It can be accessed for free 24/7 all year around. The surrounding attractions however need to be paid for.
