Newark is a city in New Castle County, Delaware, 12 miles west-southwest of Wilmington. Despite the fact that Newark is located roughly halfway between Philadelphia and Baltimore and is part of densely populated New Castle County, there is a large amount of public parkland--over 12,000 acres - surrounding the city. To the south is Iron Hill Park (part of the New Castle County Park System), to the west (in Cecil County, Maryland) is Fair Hill Natural Resources Management Area, and to the North is White Clay Creek State Park and White Clay Creek Preserve (in Chester County, Pennsylvania). Also nearby is Middle Run Valley Natural Area, which is part of the New Castle County Park System. These parks provide ample hiking, mountain biking, and horse back riding opportunities. Fair Hill Natural Resources Management Area and much of White Clay Creek State Park consist of land formerly owned by the Du Pont family that was later ceded to the states of Maryland and Delaware, respectively.
