Boston has a reputation for being expensive, and some of it's earned. But the city's parks, playgrounds, and waterfront are genuinely among the best in the country — and they're free. If you build your days around free anchors and sprinkle in one paid activity, you can have a solid Boston family trip without blowing your budget.
