The Niagara Falls consist of three sections. The large Canadian falls – with their distinctive curved shape – are also known as the Horseshoe Falls. They are separated by Goat Island from the American Falls, which are separated by a small island at their south end, from the narrow Bridal Veil falls.
Each side of the falls offers a different perspective, and it is always best to visit both sides to maximize your experience. The American side gives a side-on view of the American Falls, and an observation point only 20 yards from the top of the falls. Although the Canadian side is touted for having the best view, the American side is a State Park, the oldest in the nation, so efforts have been made to preserve the natural beauty of the area and prevent the kind of commercialization that you'll find on the Canadian side. Visitors looking to experience the falls as a natural wonder will appreciate this.
Buffalo-Niagara International Airport (IATA: BUF), in Buffalo is a major airport, with flights across the United States. It is about 30-40 minutes away.

From Toronto Pearson International Airport: Take Highway 427 S to QEW towards Hamilton. Drive for about 60 mi (100 km) and then keep left to take the Regional Road 420 E/Roberts Street toward Niagara Falls Bridge to U.S. Continue onto Falls Avenue and then cross via Rainbow Bridge. Roberts Street changes to State Route 384/Niagara Street once in the U.S.
From New York, Boston, and the East Coast: Take I-90 W towards Buffalo to the 290 W. Exit onto the 190 N towards Grand Island and Niagara Falls.

You can really do a lot without a car once you get to the immediate vicinity of the Falls. If you are staying downtown you may be able to get by without a car. The toll for walking the Rainbow Bridge westbound to Canada is 50¢ (both U.S. and Canadian currency accepted), paid on the Canadian side coming into the U.S. (There is no eastbound toll.) If you travel with any baby carriage, you pay no extra toll. Do not photograph or film on the Bridge without getting Bridge Commission approval and signing a liability wavier first. You cannot walk across the Lewiston-Queenston Bridge.
Bicycling can be faster than walking to get around. The toll for bicycling and walking the bridge across the national border is the same. On the bridge sidewalk, bicyclists are officially supposed to walk their bikes, but you may bicycle on the far right lane of the Rainbow Bridge and Lewiston-Queenston Bridge like a car.
Car is a convenient option to get around, and to see the attractions surrounding the Falls.
There is ample parking on the American side of the falls, and parking on the American side and walking across the bridge may be an attractive method of getting to the Canadian side for a day trip.
If parking in the downtown falls area, there are clearly posted signs which should direct you pretty hassle-free to the tourist area. Most shops and attractions are within walking distance from the downtown falls area.
If you want to see the Canadian side, you can cross at the Rainbow Bridge (downtown) or the Queenston-Lewiston Bridge (north of the city). Be sure you have proper documentation for yourself (passport or other approved alternative) and your vehicle (registration, insurance card, etc...) If you're driving a rental car, pay particular attention to your rental contract. Unlike with Mexico, most national rental outfits don't have an issue with you traveling into Canada in it of itself - however there's a decent chance that Canadian travel is not included in your unlimited millage area, (unless the rental originated in New York State) and surcharges may apply. Remember, you can always park in downtown Niagara Falls, NY and walk across the Rainbow Bridge to enjoy the sights there.
Views of Niagara Falls are free and accessible. Access to the riverside walks and parks offer great views. You can walk across to Goat Island on the pedestrian bridge.
There are a number of attractions designed to give different experiences of the falls.

The Maid of the Mist and the American Falls
Maid of the Mist, . A boat ride, taking you down around the bottom of the falls. Some information is given about the falls, but the real experience is looking up at the falls from below and feeling the mist coming off the falls (hence the name).
