State parks are thus similar to national parks, but under state rather than federal administration. Similarly, local government entities below state level may maintain parks, e.g., regional parks or county parks. In general, state parks are smaller than national parks, with a few exceptions such as the Adirondack Park in New York, Anza-Borrego Desert State Park in California, and Wood-Tikchik State Park in Alaska, the largest state park in the United States.
