Cuyahoga Valley protects 33,000 acres of the Cuyahoga River corridor between Cleveland and Akron — a textbook case of post-industrial restoration. The river was so polluted in 1969 that it caught fire (the most famous of at least thirteen recorded fires); the corridor was protected as a national recreation area in 1974 and redesignated as a national park in 2000. Today the river hosts beaver, herons, and migrating bald eagles, and the towpath of the historic Ohio & Erie Canal runs the length of the park as a 20-mile crushed-limestone trail. The Cuyahoga Valley Scenic Railroad runs excursion trains along the same corridor. Park entry is free and there is no entrance gate. From I-77 the closest access is Exit 145 (Steels Corners Rd), about 4 miles to the Boston Mill Visitor Center.
