Cape Henlopen State Park is a Delaware state park on on Cape Henlopen in Sussex County, Delaware, in the United States. William Penn made the beaches of Cape Henlopen one of the first public lands established in what has become the United States in 1682 with the declaration that Cape Henlopen would be for "the usage of the citizens of Lewes and Sussex County." Cape Henlopen State Park has a 24-hour and year-round fishing pier as well as campgrounds. The remainder of the park is only open from sunrise to sunset, and includes a bathhouse on the Atlantic Ocean, an area for surf-fishing, a disc golf course, and bicycle and walking paths. The beach at Herring Point is a popular surfing spot. The park is a stop on Delaware's Coastal Heritage Greenway.
