I'm planning on being in Naples on September 19 and 20 and I'd like to visit Pompeii and Herculaneum and Mount Vesuvius.
According to Google Maps Mount Vesuvius is about 11mi away from Pompeii, one way. I like walking but 22mi total seems like a bit much. What options exist for getting closer to the peak?
If public transit isn't an option, how readily available are taxis in Pompeii or Herculaneum, and how close could they get me to the peak?
