The Regional Park of the Via Appia Antica comprises a 4580-hectare area with some stretches of traffic. On every day except Wednesdays, when the Catacombs of San Callisto are closed, you can use the private road leading up to the catacombs to avoid traffic on the trafficked stretch of the Via Appia Antica, and reach the traffic-limited area after the Mausoleum of Cecilia Metella. The private road is open every day from 10 am to 5.30 pm, amd the route is illustrated below. Please note: on Wednesdays, when this road is closed, you’ll have to cycle about 1 mile of the trafficked part of the Via Appia Antica or take the much longer route through the Caffarella Valley to reach the traffic-limited area of the Appian Way.
