About White Clay Creek
White Clay Creek Preserve in Chester County protects 1,253 acres along White Clay Creek — a tributary of the Christina River in the Brandywine Valley near the Delaware border. White Clay Creek is one of only two National Wild and Scenic Rivers in Pennsylvania (outside of its Delaware River designation). The preserve protects the creek’s exceptional water quality and the largest remaining serpentine barren in the eastern United States.
Things to Do
Hiking through diverse habitats (serpentine barren, forest, meadow), fishing in the nationally-designated creek, birdwatching, wildflower viewing on the rare serpentine grassland, and cross-country skiing in winter.
Getting There
Located near Landenberg in Chester County, along the Delaware border. White Clay Creek was the first creek in the United States designated as a National Wild and Scenic River (2000). The preserve connects to Delaware’s White Clay Creek State Park, forming a cross-state greenway. The area sits in the Brandywine Valley — Andrew Wyeth’s artistic homeland — with rolling Piedmont terrain, stone farmhouses, and covered bridges.
History & Ecology
White Clay Creek’s National Wild and Scenic designation in 2000 was the first in the nation applied to an entire watershed — 190 stream miles across Pennsylvania and Delaware. The Mason-Dixon Line (surveyed 1763-1767) crosses the preserve — you can literally stand on the Pennsylvania-Delaware border. The Brandywine Valley’s artistic tradition, from the Wyeth family to Howard Pyle, was inspired by this rolling Piedmont landscape.

Frequently Asked Questions
Why is Kennett Square the Mushroom Capital?
Kennett Square produces about 500 million pounds of mushrooms annually — 50% of American production. The industry started in the 1880s when Quaker farmers grew mushrooms in limestone caves. Today, the region’s mushroom houses are sophisticated operations. The annual Mushroom Festival celebrates the industry with cooking demonstrations, farm tours, and mushroom ice cream.
