We will be in Sicily in May and plan to travel around, starting in Palermo then to mount Etna and Catania area. We will pick the hire car from Palermo Notarbartolo station at the end of our stay in Palermo. My question is - can we avoid the ZTL area in Palermo, we will collect car and head eastwards. I want to ensure we avoid any fines/charges. I have looked at the map, however, there are a lot of no entry points. We will drop car back at the same location. Many thanks
