4 girls under 11 wife and I want to take them to see some of the historic sites in Boston (any recommendations greatly appreciated). Would only like to spend a day in Boston then head up the coast to Maine. Been researching Maine and got travel brochure from website but the detail is lacking. Would love to hear from people that traveled with younger children and what they would recommend we do. We aren't a sit and sun beach family but like to walk beach looking for seashells and see marine life. Like to walk/hike trails and see wildlife. Girls love anything adventurous as they don't have electronics.
