Acqua Vergine is dominated by the hills of Tenuta Collatina, with Salone Vecchio at the top and Valle Maggiore and the Mentuccia farms in the south.

One orange block around Salone is the main coloured area, and a pink road runs south from it to the Via Prenestina along the lower edge. The railway to Sulmona crosses the left side, and Lunghezza lies beyond the blue-edged boundary on the right.
