Camp David is the country retreat of the President of the United States. It is located in wooded hills of Catoctin Mountain Park near Thurmont, Maryland, about 62 miles (100 km) north-northwest of Washington, D.C.. It is officially known as the Naval Support Facility Thurmont, because it is technically a military installation, and staffing is primarily provided by the U.S. Navy and the U.S. Marine Corps.
