Is sicily in July to overcrowded

Hi:) I whould really Like to go to sicily in july but now i am scared that it will be to overcrowded there. I really dont care about the heat, I‘ ve been in south italy last year, and i think it was fine, but I don’t like beaches where every sunbed is taken and loud music is playing. I’m looking more for peace and quiet and would prefer to be somewhere with few or no people. Are there places in Sicily in July where it’s not so crowded? Do you know of any? Or how busy is it in general? Are there beaches that aren’t overcrowded, and what is it like in the cities? :)

I also enjoy camping, but unfortunately I don’t have a car, so I need to be able to get everywhere by bus or train. I’m looking forward to your replies! 😊
