Cuyahoga Valley National Park
Cuyahoga Valley National Park is an American national park that preserves and reclaims the rural landscape along the Cuyahoga River between Akron and Cleveland in Northeast Ohio.
The 32,572-acre (50.9 sq mi; 131.8 km2) park is administered by the National Park Service, but within its boundaries are areas independently managed as city parks or private businesses. Cuyahoga Valley was originally designated as a National Recreation Area in 1974, then redesignated as a national park 26 years later in 2000, and remains the only national park that originated as a national recreation area.
