From Bordeaux you can take a non-stop flight on multiple airlines, generally for under 50 EURO round-trip if you are flexible date-wise. I flew Volotea this time, which has a lot of great priced flights from Bordeaux....If not, find a tour. Mine, naturally, was food focused, light hearted and really fun. It was around three hours long and took you into the belly of Naples...Take a ferry from Naples to any of the Islands, Capri is beautiful but I spent to many summers only seeing that island, so on this trip I decided to go to Procida
