While worthy of National Park designation, this Michigan park remains nearly unseen as one of the USA's least visited in 2023, with less than 30,000 visitors.
The National Park System here in the United States encompasses 422 national park sites. These parks span across more than 84 million acres in each state and extend into U.S. territories, including parks in Puerto Rico, the Virgin Islands, American Samoa, and Guam. There is only one of those National Parks that fully closes in the winter. Do you know which park that is?
