Castle Island
A South Boston waterfront park with the granite Fort Independence, a beach, a harbor walk, and a beloved clam shack.
The call
Worth it if you are watching the budget and you only have one day.
Why
- 01
A genuinely local spot — Southie families, the harborwalk loop, planes banking into Logan overhead, and Sullivan's hot dogs and fried clams make it a low-key, free, very Boston afternoon.
Our read - 02
The catch: it's residential South Boston and a hike from downtown without a car, the fort tours are limited and seasonal, and the 'beach' is modest.
