The National Park Service (NPS) is an agency of the United States federal government, within the US Department of the Interior. The service manages all national parks; most national monuments; and other natural, historical, and recreational properties, with various title designations. The United States Congress created the agency on August 25, 1916, through the National Park Service Organic Act. Its headquarters is in Washington, D.C., within the main headquarters of the Department of the Interior.
In the United States, a national monument is a protected area that can be created from any land owned or controlled by the federal government by proclamation of the president of the United States or an act of Congress. National monuments protect a wide variety of natural and historic resources, including sites of geologic, marine, archaeological, and cultural importance. The Antiquities Act of 1906 gives presidents the power to proclaim national monuments by executive action. In contrast, national parks in the U.S. must be created by Congressional legislation. Some national monuments were first created by presidential action and later designated as national parks by congressional approval.
There are 21 protected areas of the United States designated as national preserves. They were established by an act of Congress to protect areas that have resources often associated with national parks but where certain natural resource-extractive activities such as hunting and mining may be permitted, provided their natural values are preserved. The activities permitted in each national preserve vary depending on the enabling legislation of the unit. All national preserves are managed by the National Park Service (NPS) as part of the National Park System.
The Antiquities Act of 1906 is an act that was passed by the United States Congress and signed into law by Theodore Roosevelt on June 8, 1906. This law gives the president of the United States the authority to, by presidential proclamation, create national monuments from federal lands to protect significant natural, historic, or scientific features. The Act has been used more than a hundred times since its enactment to create a wide variety of protected areas.

A national recreation area (NRA) is a protected area in the United States established by an Act of Congress to preserve enhanced recreational opportunities in places with significant natural and scenic resources. There are 40 NRAs, which emphasize a variety of activities for visitors, including hiking, camping, boating, fishing, swimming, biking, horseback riding, and wildlife viewing, in areas that include multiple-use management for both conservation and limited utilization of natural resources. They have diverse features and contexts, being established around reservoirs, in urban areas, and within forests. Due to their size, diversity of activities, and proximity to population centers, NRAs are among the most visited units of the National Park System, with six among the thirty most visited sites.
