State Parks are managed by the state governments, but overall they operate very similarly to National Parks.
The biggest difference between a state park and a national park is the governing body that oversees them. State parks are operated by state governments and national parks by the federal government.
California has the most state parks with 270, followed by New York with 215 and Washington with 212.
Some of the most iconic parks in individual states are actually state parks. This includes Big Sur in California and Niagara Falls in New York.
