The Freedom Trail
Two and a half miles of red line in the pavement, joining 16 historic sites from Boston Common to Charlestown, one way only. Walking it costs nothing, though some sites charge. The Foundation's 90-minute tour leaves the Common's visitor center daily at 10, 11, noon, 1 and 2 ($17 adults); print online tickets, as a phone won't do.
