Mount Vesuvius, Pompeii
Via del Vesuvio (Regio VI, XVI) (in English, Street of Mount Vesuvius) was part of the cardo maximus. As you can see from the photo, the pavement is very consumed for the passage of the wagons.
When you are at the Pompeii ruins, you can see Vesuvius up close and personal.
Vesuvius is a National Park in Italy. View their website for more information, but for now here are two small details.

Going to the to edge of the crater -- 6 Euro.

Visiting the major point of distruction is a mst when you go to Pompei. It is not a difficult walk, 20 min if you are fit and 35 if not so fit. It is a fairly easy walk up the mountain to the crater.
