South of Rockside Road, the Cuyahoga Valley National Park dominates the landscape deep into Summit County. Although much of the Valley's pattern of development is shaped by economic activities, the focus of this area is history and nature. The Cuyahoga River itself has been altered to a lesser extent than in other parts of the Valley. The Towpath Trail and Cuyahoga Valley Scenic Railway provide alternative means of experiencing the Valley, and the Ohio & Erie Canal is the focal point of the area's rich pre-industrial heritage.
