Brandywine Creek State Park is a state park, located north of Wilmington, Delaware along the Brandywine Creek. Open year-round, it is in area and much of the park was part of a Du Pont family estate and dairy farm before becoming a state park in 1965. It contains the first two nature preserves in Delaware. These nature preserves are Tulip Tree Woods and Freshwater Marsh. Flint Woods is a satellite area of the park and has become the park's third nature preserve. Flint Woods is home to species of rare song birds and an old growth forest. The park's forests are part of the Northeastern coastal forests ecoregion.
