The Top STEM Museums in Boston and Cambridge

Boston has more science and technology museums within walking distance of one another than just about any other city in the world. The Innovation Trail includes five of them as stops, but there are others we love — all accessible by public transit and in the Greater Boston area. Several of them offer free admission.

Broad Discovery Center (Cambridge)

A free, public educational space from the Broad Institute that showcases cutting-edge genomic and biomedical research addressing diseases from cancer to mental health. The center offers guided tours, special talks with scientists, and community outreach programs engaging visitors in real-world biomedical discovery.​ (Free admission.)

Charles River Museum of Industry and Innovation (Waltham)

Located in a restored 19th-century textile mill, this museum explores the roots of American industrial innovation through exhibits on machinery, engineering, and early manufacturing. It hosts regular maker meetups, STEAM programs, and family workshops that highlight New England’s industrial heritage.​

Draper Laboratory (Cambridge)

A nonprofit research and development laboratory known for its pioneering work in aerospace, defense, and biomedical systems, Draper continues its legacy from the Apollo Guidance Computer to autonomous robotics. A small museum in its lobby is open to the public one day a week. (Free admission.)

Harvard Collection of Historical Scientific Instruments (Cambridge)

This museum exhibits centuries of instruments that transformed science—from Galileo’s geometrical compass to early cyclotron consoles—tracing the evolution of technology and experimentation. It features rotating exhibitions, gallery talks, and educational collaborations as part of the Harvard Museums of Science and Culture network.​ (Free admission.)
