Cuyahoga Valley National Park is a destination for millions of visitors each year who enjoy mountaineering, riding the beautiful railroad, biking and picnicking. Two pastoral shelters, Ledges and Octagon, are available for reservation in the Virginia Kendall Unit of Cuyahoga Valley National Park. The Cuyahoga River flows throughout the park for 22 miles, fed by more than 190 miles of perennial and ephemeral rivulets. The Beaver Marsh and other wetlands, many creased with cattails and dense patches of duckweed, provide a home for many of the park's reptiles and amphibians and help filter contaminants from the water. With many different amenities and attractions in the park, there is something to interest everyone.
