My friend and I are traveling from Naples to the zip line: IL VOLO DELL'ANGELO in Castelmezzano. I looked on the website but it is not very clear how to get there by taking a train and what bus to take there. I have seen that taking a rental car is the easiest option but it is also very expensive to rent a car just to go to the zip line for a few hours, ideally a train and bus would be best for us. Please let me know any advice you have, I'm having a lot of trouble reading train tables and such. Thanks!
