Located just north of Jamaica Pond in the Emerald Necklace park system, Olmsted Park includes three ponds connected by the Muddy River, a series of historic pedestrian bridges, a baseball field and a network of shady paths and boardwalks. The park is named after Frederick Law Olmsted, a 19th-century landscape architect who designed the Emerald Necklace and kept an office in Brookline for years.

Olmsted park is maintained and supported by a variety of volunteer organizations, including the Emerald Necklace Conservancy, Friends of Leverett Pond and Friends of Olmsted Park, as well as the parks departments of both Brookline and Boston.

Parking is available in a lot near Pond Avenue and Chestnut Street on the Brookline side of the park, and in a lot off Willow Pond Road on the Boston side.
