deCordova Museum and Sculpture Park

A great place to go with kids to expose them to art from an early age.  The sculpture park is perfect for your active little ones who want to run and discover and enjoy the outdoors.  The sculpture park encompasses about 35 acres of land and is surrounded by trees.  Some sculptures are interactive and some integrate into the natural surroundings.  The deCordova also can be accessed with a Minuteman Library pass so that admission is free.  Additionally, in the summer they host yoga sessions for both adults and children on the weekends, as well as artist talks, and sculpture garden tours.  The museum also has workshops and is home to a nursery school.  The interior of the museum is host to changing contemporary art exhibitions.
The grounds are perfect for picnicking and enjoying a full day of exploring.
One last family-friendly point is that the restrooms all have changing tables!
