Fantastic Area Museums

• Boston Museum of Science
  Our kids/family [a Happy Hollow family] love this museum. If you are a member you get free parking for 2 hours too! They have the planetarium and IMAX. They have special exhibits (some better for older kids and/or adults - use your judgement), educational programs, reading programs, and special exhibits. There is a computer lab for ALL ages. The museum is hands-on with lots of things to discover/interact with.
• Ecotarium - A Museum of Science and Nature
  Both my kids are former Happy Hollow kids. We recommend The Ecotarium in Worcester as a great place to spend a few hours. It's a science and nature museum that also is home to some animals that couldn't live on their own. The polar bear is [my daughter's] favorite and the Hawk and Eagle are [my son's]. They have a planetarium, a train ride, and many fine exhibits to explore. If you have a Boston Museum of Science membership, you can get in for free. Otherwise, it's $10/adult and $8/child ages 3-18. Under 3 is free.
• Charles River Museum of Industry
  An exhibition ranging from a 1,000 pound bell to the latest communications equipment - kids have lots to discover.
• Boston Children's Museum
  New renovated and expanded - a great trip to the city to explore.
• Danforth Museum of Art
  A nice regional art museum with great kid's programs.
• DeCordova Museum and Sculpture Park
  The ground of the DeCordova are worth the visit on their own.
