As overdevelopment in the northern part of the state became a matter of increasing concern in the late 1960s, the state began to purchase lands adjoining a small recreational park, which in 1975 became known as Walter S. Carpenter State Park. State land acquisitions and donations from the Du Pont family and others eventually enlarged the park to over 3,600 acres. It was renamed White Clay Creek State Park in 1995. The White Clay Creek was named a National Wild and Scenic River by the National Park Service in 2000, which added an additional layer of protection to the area.

Master Plan in Progress

The Division of Parks and Recreation is beginning the process of creating a master plan for White Clay Creek State Park. The purpose of this master plan is to provide a vision and a framework for the stewardship and use of the park.

Freshwater Fishing

Millstone and Cattail Ponds offer year-round fishing for bluegill and crappie, and a catch-and-release program for largemouth bass. The White Clay Creek offers anglers the opportunity to fish for stocked rainbow and brown trout. Trout fishing opens the first Saturday in April. A fishing license is required at all times when fishing. A trout stamp is required April through June 30th and again October through November. The creek closes to all fishing two weeks prior to the opening day of trout season. Get information on fishing permits.. WARNING: The State online automated fishing license system is NOT compatible with mobile devices or iPads and may encounter printing issues with touch screen computers and Apple products.

Hiking and Biking

Over 37 miles of trails lead explorers to historic sites and scenic vistas overlooking lush valleys and impressive rock outcrops. Hikers and mountain bikers enjoy the large number of easy-to-moderate trails throughout the park. Of special interest are those at Possum Hill and the Judge Morris Estate, along with the Pomeroy Rail-Trail, which runs alongside White Clay Creek.

The Judge Morris Estate

Built in 1790, the former home of Delaware native Judge Hugh M. Morris is perfect for weddings, private parties, and business gatherings. Private tours of the Judge Morris Estate are available for groups up to 15 people. Multiple tours can be arranged for larger groups. Hold your event at the Judge Morris Estate
