3. THE FREEDOM TRAIL, BOSTON

Colonial Williamsburg may have stood in for Beantown in the ‘‘John Adams’’ miniseries on HBO, but there’s nothing like the real thing. Stroll with your dog along the 2 ½-mile red brick trail and visit Faneuil Hall, Old North Church, the Boston Massacre site, and nine other national historic sites. Maps for self-guided tours are available at the information kiosk on Boston Common.
