A must see for kids. 3 floors of unlimited fun plus a brand new (free) play ground.
For those with kids (or curious adults), a world class children's museum with interactive exhibits.
Boston Children's Museum is a children's museum in Boston, Massachusetts, dedicated to the education of children. Located on Children's Wharf along the Fort Point Channel, Boston Children's Museum is the second oldest children's museum in the United States.
Costs a dollar after 5pm on Fridays. Totally worth it, even if you have no kids..
