Eastie Beach Bash

East Boston doesn't get nearly enough credit for its beaches, and Eastie Beach Bash is a good reminder of why locals keep coming back to Constitution Beach. For one summer morning, the shoreline becomes an enormous playground filled with kayaking, fishing, beach games, sandcastle building, live music and hands-on activities that get kids off their screens and into the harbor. The best part is that it's completely free, making it one of those community events that feels refreshingly accessible in a city where family outings can add up fast. It only pops up once each summer, so if you've been looking for an excuse to spend a day on Boston's waterfront, this is one worth circling on the calendar.
