A must-do when visiting Boston with kids, the Freedom Trail is a 2.5 mile red-brick walking trail that leads to 16 historic sites, every one an important piece of the road to American freedom. I've heard of families worrying this tour would be too dull for kids, but we didn't find that to be true at all! Not every site garners kids' full attention, but it's ok to gloss over a few in order to fully investigate the ones that interest your group most. Allow older kids turns navigating along the red brick path and reading aloud about the stops along the way, and you'll be surprised at how much time they spend learning more.
