  • On April 5, 1916, the U.S. Congress heard testimony supporting the creation of a National Park Service. Conservationists, civic leaders, and government officials debated the management of parks and recreational areas. The positive testimonies resulted in the establishment of the National Parks Service Act as well as the right to create a National Parks Service, which was made official on August 25. Stephen T. Mather was named the first director.
    Today, the National Parks Service covers more than 34 million hectares (84 million acres) of land and includes nearly 400 locations. Attracting millions of visitors each year, sites include not only national parks and monuments, but historic areas, recreation areas, lakeshores, seashores, rivers, trails, and even battlefields. National parks are known for their ability to preserve history and culture, revitalize communities, and provide an atmosphere for active living. The most-visited national parks are the Great Smoky Mountains in Tennessee and North Carolina; the Grand Canyon in Arizona; and Yosemite in California.
