The Adirondack Park covers a staggering 6.1 million acres of land---making it bigger than Yellowstone, Yosemite, Grand Canyon, Glacier and Great Smoky Mountain national parks combined---and is the largest publicly protected area in the contiguous United States. With no park fees, closing hours or entrance gates, it's easy to meander in and out of the US's largest National Historic Landmark and one of its oldest protected forests without every knowing you had entered in the first place. Must visit.
