Hello,
I would like to start this topic to help anyone would like to visit Italy and know about naturism here.
I hope to add more information but for now I would like to give some general info.
First of all, most of nude places here are free-access places. There are some official authorized places (beaches) as well some accepted places that you usually cannot find in Internet but where many people could welcome you.
I hope soon to be able to write some more details but if you will be there or plan to visit Italy, I'll be happy to help you giving all tips you need.
