I am researching a day trip from Positano to visit Herculaneum and Mt Vesuvius hike to top. I think I have the Circumvesuviana route from Sorrento to Ercolano Scavi and back again down, but it's the transpo from Positano to Sorrento to catch that train and Sorrento back to Positano late afternoon that is difficult to find. I would prefer to take a ferry both ways if possible but this may not be an opportunity (date of day trip would be first few days/weekend in October 2014). The SITA bus may allow for more flexibility?
has anyone done this as a day trip traveling this way? Is this a lot to ask for a day trip?
