Millbrook Meadow is a seaside meadow accessible from King and Beach Streets. The King Street entrance is a stone stairway down to the Meadow memorializing the quarry workers of Cape Ann, while a small Welcoming Garden graces the approach from Beach Street.

The Mill Brook courses through the Meadow on its way from the Mill Pond, flowing through the Frog Pond and under First Settlers' Bridge, on its way to its outlet at the northern end of Front Beach.

The design for the Meadow focuses on the central open space and includes an area set aside for play equipment for children. In addition to the play equipment, the Meadow provides play spaces using natural materials and native plantings, such as the mooring stone and the red dogwood maze. This environment allows room for childrens' imaginations to flourish, for games to be played, and provides a place of comfort to young and old alike.
