Weather for October was good, one rainy day and mostly around 23-25. Etna is close which was good, however, make sure you go on a clear day otherwise you won't see anything. I liked visiting Mount Etna and Taormina.
We roamed around Catania at night, as we only stayed there for the first night of our Italy trip. The city itself is absolutely marvellous when it comes to sightseeing- there are so many buildings that have a decent amount of history that wonderfully adds to the Catanian culture, and of course, cannot forget the view of Mnt Enta at sunset, it’s a beautiful view. Locals overall are quite friendly, and you can get really good street foods.
