Battle Road Trail is a 5.5 mile trail that follows the path of the British Regulars and Militia during the opening battle of the American Revolution on April 19th, 1775. The trail can be traveled on foot, bicycle, wheelchair and even with strollers. The trail links Lexington to Concord and wanders through treed settings, wetlands and historic vistas of open fields and pasture-land.
The National Park Service has an excellent multimedia program at the Minuteman Visitor center (parking area) and this is a great starting point to familiarize yourself with the events on that April day. See a map of Battle road here http://www.nps.gov/mima/planyourvisit The NPS has painstakingly restored many of the buildings, sites, landscape vistas and even vegetation to the late 18th century period. It is possible to stop at various spots by car, but to truly appreciate the trail you should walk or bike it. Most of the buildings are open between the end of March to end of October, for operating hours visit http://www.nps.gov/mima/planyourvisit
