Caserta is one of the easiest day trips from Naples. Regional trains run frequently from Napoli Centrale and take around 35 to 40 minutes; the fare is cheap and the service is reliable. The Reggia is a five-minute walk from Caserta station — you can't miss it.
Drivers can reach Caserta via the A1 autostrada (exit Caserta Nord or Caserta Sud depending on direction). Parking near the palace is available but gets crowded on weekends and public holidays. For most visitors, the train is simply easier.
