60 free Niagara Falls trivia questions with answers — geography quiz, new questions added Aug 2026.
54 free Niagara Falls trivia questions with answers. Niagara Falls is three waterfalls, two countries and about 12,000 years of history, and this quiz covers all of it. The questions range over how the falls formed at the end of the last ice age, how fast they are eroding, how much water is quietly diverted to power stations, and why the American Falls was switched off for five months in 1969. Then come the people: the schoolteacher who went over in a barrel on her 63rd birthday, the tightrope walker who cooked an omelette halfway across the gorge, the seven-year-old who survived the plunge in 1960, and the film crews who brought Marilyn Monroe, Superman and Jim and Pam to the brink. Easy questions suit anyone who has seen a postcard; the hard end is for people who know their Schoellkopf from their Sir Adam Beck. Every answer has been checked against an encyclopaedia or official source, and each question shows its explanation and citation once you have answered.

Q 01The larger and taller Horseshoe Falls lies mainly on which country's side of the border?
Canada
It is the one in nearly every postcard shot and is often called the Canadian Falls. The American Falls and Bridal Veil Falls lie entirely within the United States.
Q 02The Niagara River drains which of the Great Lakes into Lake Ontario?
Erie
The river is only about 58 km long and is sometimes described as a strait rather than a river. It carries the outflow of four of the five Great Lakes.
Q 03Niagara Falls formed when glaciers retreated at the end of which ice age?
The Wisconsin glaciation
Meltwater from the newly formed Great Lakes carved its way over the Niagara Escarpment on the way to the Atlantic. The features that became the falls are only about 10,000 years old.
Q 04Which large US city lies just 27 km (17 miles) southeast of the falls?
Buffalo
Toronto is 69 km away in the other direction, and the falls sit between two twin cities that both carry the name Niagara Falls.
Q 05Visits to the falls surged in 1953 after the release of the thriller Niagara, starring which actress?
Marilyn Monroe
It was a rare film noir shot in Technicolor, and it gave her top billing for the first time. Joseph Cotten and Jean Peters co-starred.
Q 06Which boat cruise has carried passengers into the spray below the falls since 1846?
Maid of the Mist
It began life as a border-crossing ferry and is named after a supposed Ongiara legend. Since 2020 the American boats have run on lithium-ion batteries.
Q 07In which 1980 superhero sequel does the Daily Planet send Clark Kent and Lois Lane to Niagara Falls?
Superman II
Clark rescues a boy who tumbles over the railing, which makes Lois suspicious enough to throw herself into the river to test him. The scene was one of the film's newly written additions.
Q 08Which sitcom couple got married at Niagara Falls in a 2009 episode titled 'Niagara'?
Jim and Pam
The Office episode aired on NBC on 8 October 2009. Jim accidentally lets slip that Pam is pregnant, and the pair sneak off to marry privately on the boat before the church ceremony.
Q 09Two days before her 1901 barrel ride, Annie Edson Taylor sent what over the falls to test the barrel?
Her cat
Contrary to rumours, the animal survived, and posed with Taylor for photographs afterwards. Taylor herself climbed in with a lucky heart-shaped pillow.
Q 10Annie Edson Taylor chose 24 October 1901 for her barrel plunge because it was what?
Her 63rd birthday
She was a schoolteacher hoping the stunt would fund her retirement. On climbing out she said, 'No one ought ever do that again.'
Q 11On one 1859 tightrope crossing of the Niagara Gorge, Charles Blondin stopped midway to cook and eat what?
An omelette
Other crossings were made blindfolded, in a sack, on stilts and pushing a wheelbarrow. His wire ran across the gorge near the site of today's Rainbow Bridge, not over the waterfall itself.
Q 12Blondin's hardest crossing, on 14 August 1859, involved carrying whom on his back?
His manager
Harry Colcord reportedly begged him to stop halfway. Blondin's final crossing in 1860 was watched by the Prince of Wales.
Q 13What did Nik Wallenda have to do for the first time on his 2012 Niagara Falls wire walk?
Wear a safety harness
Q 21The first written description of the falls, in 1677, is credited to a missionary of which nationality?
Belgian
Father Louis Hennepin had been travelling with the explorer La Salle. A French Jesuit, Paul Ragueneau, had probably seen the falls some 35 years earlier.
Q 22The Native American word Ongiara, one proposed source of the name Niagara, means what?
Thundering water
Other theories trace the name to an Iroquois town called Onguiaahra, 'point of land cut in two', or to a Mohawk word for the neck of land between the two lakes.
Q 23What has been stranded on the rocks above the falls since August 1918?
An iron scow
The live ABC special followed a two-year legal battle for permission on both sides of the border. His rope was 550 metres long.
Q 14Nik Wallenda's 2012 walk was the first crossing of the falls area in how many years?
116
He needed special permission from both governments. The last tightrope crossings of the gorge had been part of a Victorian daredevil craze that ended in the 1890s.
Q 15In which year did the only recorded complete freeze-up of the river and falls occur?
1848
An ice jam upstream choked off the flow on 29 March that year. In 1912 the American Falls froze solid, but the other two kept flowing.
Q 16In which year did the Army Corps of Engineers temporarily dam and dry out the American Falls?
1969
Engineers wanted to study the huge pile of rock at the base and see whether it could be removed. The plan was abandoned as too expensive, and the dam was dynamited in November.
Q 17By flow rate, Horseshoe Falls is the most powerful waterfall on which continent?
North America
The peak flow ever recorded there was 6,370 cubic metres per second. Worldwide the combined falls rank about seventh for flow.
Q 18Roughly how long until Niagara Falls erodes the remaining 32 km to the lake and ceases to exist?
About 50,000 years
Since forming near Queenston and Lewiston about 10,900 years ago, the falls have already retreated some 10.9 km southward. Hydro diversion has slowed the erosion considerably.
Q 19Roughly how tall is Horseshoe Falls?
57 m (187 ft)
The American Falls is only 21 to 30 metres because giant boulders piled at its base cut the drop short. Horseshoe Falls is about 790 metres wide.
Q 20Goat Island, which splits the falls in two, was earlier named after which flower?
Iris
The current name comes from John Stedman, an early miller who kept a herd of goats there. Luna Island is the sliver of land between the American and Bridal Veil Falls.
The two men aboard were rescued, but the vessel is still visible in a rusting state. A storm on Halloween 2019 shifted it about 50 metres.
Q 24Niagara's Honeymoon Bridge, replaced by the Rainbow Bridge, collapsed in 1938 because of what?
Ice in the gorge
The Rainbow Bridge stands just downriver from the falls and offers the closest view of them from any crossing. The oldest bridge over the river is the Whirlpool Rapids Bridge.
Q 25What nickname is given to the exterior elevators of the Skylon Tower on the Canadian side?
Yellow Bugs
The tower opened in 1965 and stands 160 metres above street level. Because it is so close to the border, both Canadian and US aviation authorities had to approve it.
Q 26An engineer from which country designed the 1916 Whirlpool Aero Car over the Niagara Whirlpool?
Spain
Leonardo Torres Quevedo also built early chess-playing automata and airships. The car has been upgraded several times, most recently in 2023.
Q 27For how much did Hooker Chemical sell the Love Canal landfill to the Niagara Falls school district in 1953?
One dollar
Some 19,800 tonnes of chemical byproducts lay beneath the site. The resulting disaster prompted the first US presidential emergency declaration for a non-natural disaster, in 1978.
Q 28The July 1814 Battle of Lundy's Lane, in what is now Niagara Falls, Ontario, was part of which conflict?
The War of 1812
The Canadian city itself was formed in 1904 when the town and the village of Niagara Falls amalgamated. Its 2021 population was about 94,000.
Q 29Which company was hired in 1893 to design the alternating-current power system for the falls?
Westinghouse Electric
It used Nikola Tesla's AC patents, which is why a statue of Tesla stands on Goat Island today. The Adams Power Plant Transformer House survives as a landmark.
Q 30The Robert Moses power plant was built after which nearby hydroelectric station collapsed in 1956?
Schoellkopf
Jacob Schoellkopf's company had opened its first station on the river in 1881. The replacement plant is named for the famous city planner Robert Moses.
