The lush greenery and sparkling streams of White Clay Creek State Park offer a refreshing change of pace from the encroaching urban development of New Castle County. Whether it's an activity at the Carpenter Recreation Area, a retreat into the pristine White Clay Creek Preserve, a hike along the peaceful trails of Possum Hill, or just a few hours of fishing in the creek, visitors of all ages will enjoy the natural beauty of the White Clay Valley. Nestled in the northwest corner of Delaware, the park's forested hills create a relaxing oasis of cool green leaves and rushing streams.

Of the many activities available at the park, hiking is one of the most popular. 20 miles of trails lead explorers to scenic vistas overlooking lush valleys and impressive rock outcrops. Hikers can also stroll though history at White Clay Creek. The Twin Valley Trail leads hikers to the Arc Corner Monument, which marks one end of the curved boundary between Pennsylvania and Delaware.
