White Clay Creek State Park
White Clay Creek State Park is a Delaware state park along White Clay Creek on 3,559 acres (1,440 ha) in New Castle County, near Newark, Delaware in the United States. North of the park is Pennsylvania's White Clay Creek Preserve, and the two were originally operated as bi-state parks to jointly protect the creek, but now they operate separately.
