The area where the Villa stands is in a commanding position, below the slopes of Monte Tuscolo. The park that surrounds the Villa is more than 15.000 sq m and is predominantly rural.

The greenery is mainly arboreal, being composed in the past by fruit trees, lemon trees, a wineyard, a small kitchen garden and an Italian garden. Nowadays the park has old long trunk trees such as holm-oaks, Orientalis plane trees – it is thought they are the same frescoed in the Room of Eliseo of the Villa – Lebanon cedars, Deodara cedars, Jubaea Chilensis palms, Caucaso pines and sequoia. The horse-chestnuts along the sides of the entrance of the Villa have been removed during the restoration works.

In 1992 ADSI (Associazione Dimore Storiche Italiane – Italian Historic Residence Association) and FAI (Fondo per l’Ambiente Italiano – Fund for the Italian Environment) advertised a national contest for the restoration of Villa Grazioli Old Park.: 26 groups of highly-qualified experts throughout Italy took part and the winning project was leaded by architect Romano Greco, which aimed at valorizing the existent trees such as holm-oaks, planes, cedars, as well as the bushes of box remaining from the Italian garden.
