Whether you're experiencing it from the water or land, this is a must-see in Boston. You can't beat the skyline views and the walk/biking path makes it accessible for strollers. Bring a picnic lunch or dinner and enjoy all the people watching! Bonus points if you go from mid-April to early May and catch the gorgeous Cherry Blossoms!
Avid hikers, this is a must-see spot! Outside of Worcester is Purgatory Chasm, a hike through a huge chasm with gorgeous views and climbing for days. My big kids (4 and 7) can navigate this trail without help, but with a watchful eye. *Not stroller friendly*
Castle Island is one of those spots I love to visit mid-week or off-season. While the crowds can be rough on the weekends, it's a great location for a day trip. The paved path around the fort makes easy access for bikes, wheelchairs, and strollers. The historical site, playground, and beachfront offer plenty to fill a few hours.
