The Freedom Trail

A 2.5-mile red-brick walk through the birthplace of the American Revolution

Towns decide what they are going to be, usually in a handful of streets. These are the ones in Boston. 16 stops over 2.6 miles, about two and a half hours of walking. Every stop narrates itself when you get there, at whatever pace you feel like walking.

It is one of 50 tours in Boston, each taking a different line through the city. Nothing is booked and nothing expires, so you can start it on a whim and finish it whenever you like.
