The state of New York's two largest landforms are the Adirondack and Catskill Mountains, which together cover one-third of the entire state. The Adirondack Mountains constitute the larger landform of the two, and they reach 5,344 feet at their peak. New York also has many lakes, including Lake Champlain, Lake George and Oneida Lake.
New York's many mountains are part of the Appalachian Mountain range, which extends into the states of Vermont and New Hampshire as well as into the southern region of Canada. Other notable lakes in New York include Lake Erie and Lake Ontario, two of the Great Lakes, which also border Canada to the north. The state of New York also contains many valleys, forests and rolling hills, as well as rivers, waterfalls and beaches throughout the state. Significant rivers include the Genesee, Hudson, Delaware and Mohawk rivers.
New York is also home to what many consider one of the greatest waterfalls in the world, Niagara Falls. This major landform sits on the border between the United States and Canada and is the most powerful waterfall in North America. Many of New York's landforms are major tourist attractions and draw countless visitors to the state each year.
