Most of the national parks in the United States are scattered across the U.S. continent. The geographically separate states of Hawaii and Alaska are home to one and eight national parks, respectively. Another park is also situated in American Samoa, an unincorporated territory of the United States.
The United States currently has 59 national parks recognized by the National Park Services, including the Pinnacles National Park in California, which was declared a national park in 2013.
Yellowstone National Park was the first national park in the United States. It was declared a national park in 1872 as a way to protect and preserve the outstanding natural flora and fauna and the geographical formations in the area. The Pinnacles National Park, the youngest national park in the country, is valued for its stunning rock formations and exotic flora and fauna.
Only half of the states have a national park and only a fourth of these parks are scenic and geographically large parks. Among these traditional national parks are Yellowstone, Yosemite and the Grand Canyon. These parks are also among the 14 national parks recognized by UNESCO as World Heritage Sites.
