Cuyahoga Valley

The 70-acre Beaver Marsh was once a salvage yard; in 1984 Sierra Club volunteers led its largest cleanup, and today the Towpath Trail crosses the marsh on a boardwalk.

The words

  1. Beaver Marsh

    Open water, water lilies and wetland plants support frogs, turtles, waterfowl and mammals at Beaver Marsh. Its resident beavers remain active in winter rather than hibernating.

  2. Blue Heron

    Great blue herons stalk fish, frogs and other small animals along the valley’s waterways. They nest in groups called heronries, usually high in trees near water.

    Did you know?

    At nest-building time, the male gathers a stick and presents it to the female, who adds it to the nest.

  3. Boston Store

    Boston Store served the Boston Land and Manufacturing Company in a busy canal town. Boatyards, a brickyard and mills nearby show how waterborne trade supported local industry.

  4. Brandywine

    Brandywine Falls drops over hard Berea Sandstone above softer shale layers. Brandywine Creek carved the waterfall and gorge, exposing a sequence of rocks formed from ancient sediment.

  5. Burning River

    In Cleveland, north of the park, oil and debris on the Cuyahoga burned on June 22, 1969. The fire became an environmental symbol, while cleanup efforts were already underway.

  6. Covered Bridge

    Everett Covered Bridge spans Furnace Run, linking farm roads with the valley’s former canal economy. The crossing seen here is the National Park Service’s historically accurate 1986 reconstruction.

  7. Cuyahoga

    The Cuyahoga follows a U-shaped course, flowing south before turning north toward Lake Erie at Cleveland. Meltwater from retreating glaciers helped shape the route through the park’s valley.

  8. Hale Farm

    Jonathan Hale began farming here after arriving in 1810. The brick farmhouse and recreated village at Hale Farm & Village interpret the valley’s agricultural life, including the work of hired families.

    Did you know?

    A recorded farm recollection describes neighbors gathering on threshing day, with wagons bringing grain to a machine at the barn.

  9. Ice Box Cave

    Ice Box Cave lies at the Ledges. When checked on October 25, 2026, NPS listed it closed to limit white-nose syndrome, a disease affecting hibernating bats.

  10. Kendall Lake

    Civilian Conservation Corps crews dammed Salt Run in 1934 and 1935 to create Kendall Lake. Built during the Great Depression, it gave nearby city residents a place for outdoor recreation.

    Did you know?

    The lake once had a swimming beach, while winter recreation included a toboggan run and ice skating.

  11. Lock Tender

    A canal worker who operated locks, changing water levels to move boats uphill or downhill.

    Charles Carter, who lived near Lock 26, was both a locktender and a canal boat captain. His family combined canal work with farming and a local dairy trade.

  12. Ohio and Erie

    The Ohio & Erie Canal linked Lake Erie at Cleveland with the Ohio River at Portsmouth. Through the valley, its boats carried farm produce and other goods to markets beyond the region.

  13. Ritchie Ledges

    The Ritchie Ledges expose rock made from ancient sand and pebbles. Erosion shaped their cliffs and crevices, while stored rainwater helps create a cool, moist habitat nearby.

  14. Towpath Trail

    The Towpath Trail follows the route where mules once pulled canal boats loaded with goods and passengers, linking valley communities to a wider transportation network.

  15. Valley Railway

    The Valley Railway began service in 1880, carrying coal, stone and agricultural goods toward Cleveland. Its depots also brought passenger travel, mail and telegraph news to valley communities.

    Did you know?

    Faster rail transport changed farm trade: milk could reach city markets fresh, rather than first being made into cheese.
