Niagara Falls

Niagara Falls is a large and spectacular series of waterfalls located along the border of New York State in The United States and the Canadian province of Ontario. If you want all the fiddly technical details, go check out the relevant article on The Other Wiki, and if you want to know the sights to see, check out the article on Wikivoyage.

In popular culture, the falls are best known for four things:
 * Being a destination for honeymooning couples, who dress up in full rain-gear, go out in tour boats and get drenched by the spray.
 * Being a destination for older couples to get away from people they know (hence the cities' nickname "Viagara Falls").
 * Idiots/Thrill-seekers going over them in some sort of reinforced barrel - and very, very occasionally surviving the trip.
 * Monumental Damage, where the falls are under (usually joking) threat of being destroyed/frozen/diverted.

In a case of Truth in Television, they have a Cave Behind the Falls.

If the Falls appear in any sort of comedy or adventure context, someone's going over them, with or without a barrel.

Often suffers from Television Geography.

And if you're wondering about going there as a tourist destination, please make sure you're on the Canadian side of the border, even if it is a city-sized Tourist Trap. The American side is a Thriving Ghost Town, due to Canada having
 * 1) a much better view of the falls (as shown here), and
 * 2) high-rise casinos.

Anime and Manga

 * Featured in one episode of Dinosaur King.
 * The falls - and the Cave Behind the Falls - feature in one episode of Speed Racer.

Comic Books

 * One of hero Tom Strong's enemies dies by falling off the Falls.
 * In some versions of the Buck Rogers franchise, Earth's capital city is located at Niagara and/or Buck has his headquarters behind the actual falls.
 * One Captain Marvel story has Dr. Sivana plot to destroy the Falls with a barrel full of explosives. He leaves the scene for a moment, when Ibac the Terrible rushes onto it, on the run from an Abhorrent Admirer. Ibac sees the barrel, dumps the explosives, and stuffs himself inside, at which point Sivana comes back and, unaware of the switch, dumps the barrel (and the unaware of the plot Ibac) into the water over the Falls. Ibac is rescued by the police, who think he's one of those daredevil nuts who try to go over the Falls in a barrel, to which Ibac dizzily responds, "Is that what I've been doing?"

Film

 * In Peter Jackson's The Fellowship of the Ring the shot of Boromir's boat going over the Falls of Rauros is not CGI - it's actually a stock aerial shot of Niagara with a CGI boat added (over footage of a barrel, if the audio commentary is to be believed).

Literature

Recorded and Stand Up Comedy

 * The falls is often the MacGuffin in a classic comedy routine done by many performers, including Abbott and Costello and The Three Stooges: a deranged man retells how he finally tracked down the one who wronged him at.. "NIAGARA FALLS!! Slowly I turned.. step by step..."
 * Which is made doubly hilarious (at least in the Stooges version) in that he meets the one who wronged him at the end of the bit... only to greet him as an old pal and say that they'd buried the hatchet a long time ago. Cue Niagara Falls from the third Stooge on stage, and both of them start up for the beating.
