The main reason to visit the Niagara Falls is mainly to see the falls. There are different ways to do this, however the most popular and used by tourist way is to jump on a Maid of the Mist boat.
These little coal-powered steamboats have been shuttling visitors to and from the base of the falls since the 1840s. The Maid of the Mist practically dunks you under the falls.
The Maid of the Mist docks on both the American and Canadian side, so you won’t have to worry about crossing any borders.
The Niagara parks Botanical Gardens are other attraction around Niagara Falls.
If you like nature, the gardens are a must-see. During the summer, guided horse-and-carriage tours allow you to explore the gardens in style. The gardens are also home to the Butterfly-Conservatory, where several thousand butterflies flit and flutter among brightly colored flowers.
If you enjoy the history, you definitely must see the Old Fort Niagara.
Located on the U.S. side of the falls, this 17th-century fort has changed hands between French, British and American troops. This site has seen action during numerous wars, including the American Revolution and the French and Indian War, making it the longest operational fort in North America. Today, the fort occupies one of the most scenic areas in western New York, overlooking both Lake Ontario and the Niagara River.
