At 450 acres, this is Rome’s second largest park. It is more wooded and less finely manicured than Borghese or Pamphili. A private area is under control of the Egyptian embassy. The park has an artificial lake, a public swimming pool, and one can rent canoes, bikes, or horses. In summer there’s the Rome Meets the World Music Festival and numerous other outdoor concerts. For running, there are numerous paths throughout the park, including the perimeter of the fort, totaling ~3 miles. For a longer run, combine with Villa Borghese Park, taking Via Salaria, Via Panama, or Villa Romania to Via Giaocchino Rossini.
