Cuyahoga Valley is the only national park in the state of Ohio and one of three in the Great Lakes Basin, with Isle Royale National Park in Lake Superior and Indiana Dunes National Park bordering Lake Michigan. Cuyahoga Valley also differs from the other national parks in America in that it is adjacent to two large urban areas and it includes a dense road network, small towns, four reservations of the Cleveland Metroparks, eleven parks of the Summit Metro Parks, and public and private attractions.
