Cape Cod - - we would always stop at Plymoth Plantation, Ocean Spray cranberry bogs, and Edivil Railroad (sp?). Which are all before you reach the Cape. But what I remember the most about my trips to Cape Cod was the family bike trips up and down the Canal (sorry I don't remember the name of the Canal). You know the bridges you cross going onto or off of the Cape, well they are going over a canal from the north to the south side of the cape. On each side there are bike trails you can walk or ride the length of the Canal. If I recall correctly, the one on the Boston side of the Canal is an easier bike trail (much flatter).
It's the Cape Cod Canal. It's beautiful there. One side is the Sagamore bridge and the other is the Bourne Bridge.
Other places to visit in Mass. - We would always go to the various historic places around Mass., there are a ton. In Boston, I enjoyed places like the Science Museum, the aquarium, and the Children's Museum. After traveling around the country I can tell you these are some REALLY good museums for kids. The Big-E in September was always fun (but I would do that as a school field trip, not a family trip). A different experience, but probably one of my most enjoyable as a kid and one I enjoy going back to as an adult, when I travel back to Mass. is Old Sturbridge Village ( www.osv.org ). It is not an amusement park, or a fancy kids place with lots of entertainment, but as a kid I would spend days there exploring. Thinking back to fun family outings around Massachussetts, I think about Old Sturbridge Village first. Amazing how much fun you can have in a place that has no electricity.
Massachussetts is full of places to take the kids. A family outing or vacation does not have to be to some fancy park. Salem, historic sites around Boston, Plymouth, Old Sturbridge Village, Boston Science Museum, Boston Aquarium, Boston Children's Museum, and a handful of odd little places that after the many years since my childhood I can't remember. Have fun staying in New England this summer. I have traveled around the world and across the US. I have lived in New England, the mid-west, and now living in Washington State. Trust me, Massachussetts is a fabulous place to grow up and explore. Enjoy.
I have lived here all my life and I haven't seen most of what this state has to offer. A shame really. Alot of the things I haven't visited since I was in school and that was years ago. Now having my own children I want them to see what MA has to offer. Another sad note is I live in America's Hometown and my girls have never been on the Mayflower. On of the things that we will do this year is explore close to home. We will see all the sites of Plymouth.
I am also thinking about taking them next summer to Santa's village and Story Land as we will be going to Disney in January.
