I will visit Napoli in this August, and I am wondering if I can spend one day to visit Pompeii, Herculaneum, and Paestum. If not, which one do you think I should drop? People said that Herculaneum and Pompeii are not too much different. So maybe I should drop Herculaneum?
Also, is Paestum served by Crcumvesuviana train? You know, because to reach Pompeii and Herculaneum ruins from Napoli, we need Circumvesuviana train, not ordinary train (it can but we have to walk far). So I am thinking if Paestum is also served by Circumvesuviana, that would be great. I would use it to Paestum, and then on the way back, I will visit Pompeii and/or Herculaneum (or the other way around). I check in trenitalia.it, there is a train from Napoli to Paestum, but I don't know if that is Circumvesuviana or not.
Thank you for your suggestions.
