Park service rangers lead small-group tours of the historic office wing and grounds of the site, offering visitors glimpses into the workings of an early-twentieth century design office, as well as teaching them about the work of the Olmsted firm and the practice of landscape design in general. Seasonally, Olmsted NHS rangers also lead walks of the public spaces designed by the firm such as the Arnold Arboretum in Jamaica Plain, the Fens in Boston and World's End in Hingham, Mass.
