About the Park

Nestled along the Red Clay Creek and home to the world’s largest operating collection of Stanley Steamer cars, Auburn Valley State Park highlights Yorklyn’s rich industrial history. The historic Marshall Brothers Paper Mill in its undisturbed condition complements the Queen Anne Mansion and surrounding estate, while transitional forest and remediated wetlands outside the former National Vulcanized Fiber site round out the park. Rare 19th century bridges from across the country are restored and brought to Auburn Valley to help tell the story of the industrial revolution. Outcroppings of Baltimore Gneiss dot the Red Clay Valley around the park, while hidden and historic twin ponds await hikers and anglers at the end of the Oversee Farm Trail. Steamin’ Days offer rides on the 1/8-scale Auburn Valley Railroad and in the park’s antique Stanley Steamer cars.

Delaware’s Newest State Park

Nestled in the Piedmont’s Red Clay Valley, visitors to Auburn Valley State Park will discover the history of the Marshall Family, Yorklyn’s rich industrial history, and revitalization of this site. Previously known as Auburn Heights Preserve, Auburn Valley State Park features new hiking and paved biking trails, the historic Marshall Mansion completed in 1897, the Marshall Steam Museum, the Auburn Valley 1/8-scale railroad, and much more.

Special thanks go to Tom and Ruth Marshall for their generous donation of this Auburn Valley estate to Delaware State Parks.
