Public softball fields are a great place to organize impromptu softball games or set up a small team. Softball fields are available throughout the Boston area as part of the city's park system, and they can be used (first-come, first-served) by the public when not reserved.

Softball reservations in Boston are handled by the Parks and Recreation Department of the city (click here).
