Route description
Head northwest from Philadelphia on I-76 to Valley Forge, where Washington’s army spent the winter of 1777–78. The loop road passes rebuilt huts, memorials and his stone headquarters.
Drive south through the rolling Chester County countryside to Longwood Gardens, which needs half a day for its conservatories and fountains. Nearby Kennett Square is the self-proclaimed mushroom capital of the world, with a lively main street.
US-1 leads east to Chadds Ford and the Brandywine Museum of Art, dedicated to the Wyeth family. Cross into Delaware on State Road 52, a lovely road past horse farms, to Winterthur and then to Hagley, the gunpowder mills where the du Pont fortune began.
Finish at New Castle, a colonial town on the Delaware River with cobbled streets and the old courthouse. The gardens are at their best from April to June; many sites have timed tickets, so reserve for weekends.
