Niagara County is in the extreme western part of New York State, just north of Buffalo and adjacent to Lake Ontario on its northern border and the Niagara River and Canada on its western border.
The primary geographic feature of the county is Niagara Falls, the riverbed of which has eroded seven miles south over the past 12,000 years since the last Ice Age.
The Niagara River and Niagara Falls, are in effect, the drainage ditch for four of the Great Lakes which constitute the largest supply of fresh water in the world.
The water flows north from Lake Erie, then through the Niagara River, goes over Niagara Falls, and then on to Lake Ontario and the St. Lawrence River, eventually emptying into the North Atlantic Ocean.
Today, tourists and visitors to the Falls see a diminished flow of water over the Falls, since a portion of the flow has been diverted for hydroelectric power purposes.
Both the American and Canadian side of the Niagara River have massive electrical power plants.
The spectacular Niagara Gorge is the path Niagara Falls has taken over thousands of years as it continues to erode.
Niagara Falls started at the Niagara Escarpment which cuts Niagara County in half in an East-West direction.
North of the Escarpment lies the Lake Ontario plain, which is a fertile flatland that is used to grow grapes, apples, peaches and other fruits and vegetables.
Viticulture, or wine culture has begun to take place, with several wineries below the escarpment.
This has helped to improve the depressed economy of the region.
To further capitalize on economic development, the state has created the Niagara Wine Trail.
According to the U.S. Census Bureau, the county has a total area of , of which is land and (54.12%) is water.

At Virginia Falls or Nailicho in Dene, the river plunges in a thunderous plume.
Including the Sluice Box Rapids above the falls, it is more than twice the height of Niagara Falls.
In the centre of the falls is a dramatic spire of resistant rock, called Mason's Rock after Bill Mason, the famous Canadian canoeist, author, and filmmaker.
The falls were initially located downstream at the East end of Fourth Canyon, and over the centuries carved through the limestone rock that surrounds the river.
This continuous erosion shifted the falls upstream and created the Fourth Canyon.
Due to the mist, the immediate vicinity of the falls is home to several rare orchid species.
There is a proposal to rename the falls after former Prime Minister of Canada Pierre Trudeau.
Downstream from the falls, there are many notable rapids on the river including Figure Eight, George's Riffle, and Lafferty's Riffle.
