White Clay Creek State Park is one of Delaware’s most beautiful natural sanctuaries. It’s an escape from the crowded towns and busy streets of New Castle County, and it’s located in Newark, right up near the Maryland and Pennsylvania border. Speaking of the border – do you know what is a perfect arc? If you don’t, you will by the time you hike the park’s Twin Valley Trail!

White Clay Creek State Park is home to a network of trails that cross fields, ponds, streams, and patches of forest in the northwestern corner of New Castle County.
