The playground at Castle Island is awesome! |
You do the loop around the fort and play at the playground. The playground there is pretty great! Kids love watching the planes taking off from Logan! For more beachy activities, you can look for shells and play in the sand, even if the weather is cool.
While you're there, have a picnic. The picnic tables are plentiful so either pack a picnic or grab some food from Sullivan's. The food is super inexpensive. Even a lobster roll is only $10! If you get there early enough, they even have breakfast sandwiches for only about $3. If you go on a chilly day, warm up with hot chocolate, chowder, or lobster bisque.
It's a cheap outing and lovely in the fall. Plus, it's right in Boston!
