About the Venue

Boston Playground is a family-focused indoor playspace in Chelsea designed for active, screen-light fun rather than a café-style visit. Families can use open play sessions on select weekday afternoons, while weekends and many other time blocks are reserved for private parties. The space is geared to children from infancy through about age 10 and includes climbing, running, ball-based, and imaginative activity zones plus a dedicated party room.
