Auburn Valley State Park (formerly Auburn Heights Preserve) is a state park, located in Yorklyn, Delaware, United States. The park, which is around 360 acres,[1][2] preserves the former home and estate of the Marshall family as well as portions of the family's former mills alongside the Red Clay Creek and additional land purchased by the state.[3] The preserve contains several miles of trails open to walking and biking, including a 1.2 mile paved loop. The state owns conservation easements on 160 acres of privately owned land adjacent to the park to help maintain the park's rural character.[4]
The park also features what the state bills as the largest collection of operational steam cars in the world, and a miniature coal-powered train that runs on tracks encircling the estate. The mansion, mills, and steam museum were added to the National Register of Historic Places in 1980 as the Auburn Mills Historic District.
