Many of the sites of Boston National Historical Park are located along the 2.5 mile (4 km) Freedom Trail. The trail in best experienced on foot. Maps and information about Boston and the Park can be found at the following locations:

Boston NHP Visitor Center- 15 State Street  Bathrooms, Free maps, Information, Guided Tours in season, Freedom Trail Slide Show

Navy Yard Visitor Center- Building 5, Charlestown Navy Yard Bathrooms, Free maps, Information, Navy Yard introductory video.

City of Boston Visitor Center- Boston Common  Bathrooms, Maps, Information

Fees are collected at the other privately owned and operated sites by self supporting associations working cooperatively with the park, including Old South Meeting House, Old State House, and Paul Revere House. These sites rely on admission fees as they do not receive federal funding for operations and therefore do not accept the National Parks Pass for admission. There is no fee at the federally owned sites, including the Bunker Hill Monument, U.S.S. CONSTITUTION, and Dorchester Heights Monument. Ranger-led programs on the Freedom Trail and at Faneuil Hall are also free.
