There are nine national parks located in the state of California managed by the National Park Service. National parks protect significant scenic areas and nature reserves, provide educational programs, community service opportunities, and are an important part of conservation efforts in the United States. There are several other locations inside of California managed by the National Park Service, but carry other designations such as National Monuments. Many of the national parks in California are also part of national forests and National Wildlife Refuges, and contain Native American Heritage Sites and National Monuments.
