Yosemite National Park, Muir Woods National Monument, Apostle Islands National Lakeshore, Wright Brothers National Memorial, San Juan National Historic Site, Big Cypress National Preserve, and Oregon National Historic Trail. All of these sites are managed by the National Park Service. All of them are part of the United States National Park System. The names are designed to help explain their purpose and level of protection. Sometimes the names are confusing and sometimes don’t make sense. To most visitors, the designation doesn’t matter but learning the national park system nomenclature can help understand the importance of these American Treasures.
