Auburn Valley Master Plan



DNREC’s Division of Parks and Recreation is in the process of updating the Auburn Valley Master Plan, which guides development of Auburn Valley State Park.

About the Park

A view of a large stately home, with wrap-around porches, nestled in a valley.

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.

Learn more about the park, trails and programming.
