Adirondack State Park
Covering 6.1 million acres in upstate New York, Adirondack Park is the largest protected area in the contiguous United States. It contains 3,000 lakes, 30,000 miles of waterways and 2,000 miles of hiking trails.
Because of its chillier, elevated climate, fall colors come early in Adirondack Park. Be there in time to see the leaves peak in the last two weeks of September.
