If you're looking to (more than) stretch your legs, the 199-mile Mason-Dixon Trail begins/ends in Chadds Ford. Along the way, the trail ambles through the Pennsylvania–Maryland–Delaware borderlands, easing past the Susquehanna River and eventually connecting to the Appalachian Trail in Cumberland County. In Southeastern Pennsylvania, the trail spreads through some gorgeous Brandywine Valley countryside.
The easternmost terminus of the trail is about 0.5 miles south of the intersection of Fairville Rd and US 1 (Baltimore Pike). Check the Mason-Dixon Trail website for detailed information on trail conditions and updates.
