Cuyahoga Valley National Park is a National Park in Ohio that is between the cities of Akron and Cleveland. The 32,000 + acre park was a National Recreation area since 1974, but in 2000 became a National Park. It has the Cuyahoga River running through it and the original Ohio-Erie Canal system with now renovated locks. There is a scenic railway you can take down in the valley for sightseeing and lots of walking trails.
