Directions From Sorrento to Naples Archaeological Museum

Craig,

In the same situation, I'd just take the Circumvesuviana to Napoli Centrale (about an hour), and then get a Cab to the Archeological Museum.

As Ken said, you can take the Circumvesuviana to Napoli Centrale, but you can save some €€ by taking the Metro from Centrale one stop (as I recall!) to the museum. It is a short walk from the Metro to the museum. I think the Circumvesuviana ticket may allow you to jump on the Metro for one trip.

I followed the instructions in an RS Italy guidebook. It took a few minutes (10 or more?) to walk from the Circumvesuviana platform to the entrance to the metro platform, and I recall a moving walkway. There was an exit from the metro right to the museum, but I took the wrong one and jaywalked to cross the busy street. I did get a nice photo of the museum facade, though.

You can easily take the metro to the museum from the train station. I hope you have better luck with rooms being open at the museum. Was here in July & Oct of 2013 and both times the mosaics rm was closed as were other rms. We heard they were short staffed. There is a board by tkt office telling you what is closed.
