Biking is permitted; just keep in mind we are a 50 acre park with no trails other than the road throughout the park. Another scenic bike ride on the Brandywine Battlefield is at Sandy Hollow Park, which is a mile looping trail on the Battlefield. See a map of our Park here: http://brandywinebattlefield.org/plan-a-visit/ Sandy Hollow: https://www.birminghamtownship.org/history/pages/sandy-hollow-heritage-park
