Boston is most easily accessed by its public transportation system, the MBTA. Commonly called the "T", public transportation provides easy access to both of Boston National Historical Park's visitor centers.
To get to the Faneuil Hall Visitor Center, take the Orange or Blue line to State and exit onto State Street. Walk down Congress Street north about half a block to arrive at Faneuil Hall.
To get to the Charlestown Navy Yard Visitor Center, you have two man options. You can pick up the Water Shuttle at Long Wharf, which will drop you off at Pier 3 in Charlestown. Walk to the head of the dry dock, and take a left into the Charlestown Navy Yard.
You can also take the 93 bus to the "Constitution Road" stop, and walk into the Charlestown Navy Yard from there.
