The Adirondack Mountains, located in eastern upstate New York, are an all-season, year-round vacation destination. Created by the New York State legislature in 1892, the Adirondack Park covers 9,375 square miles, an area more than double the size of Yellowstone and Yosemite National Parks combined. The Park is a mosaic of 2.5 million acres of state-owned Forest Preserve intermingled with 3.5 million acres of private land. The Adirondack Park is the largest park, federal or state, in the United States outside of Alaska.
