Depends on what you want to see, since almost every town here has a glorious history and can boast of worthy sights. If you are interested in one-day excursions - it is definitely worth visiting the capital of the island - the city of Palermo, as well as look into its suburbs of Montreal, for the sake of the magnificent cathedral of the Duomo. Also, you should not bypass the ancient volcano Etna. His marvelous lunar landscapes with black sand are the island's business card.

Finally, if you are interested in antique monuments, you can take the same chance to go to Agrigento, Syracuse or Taormina. If you want to not just "take a look" around, but also a little "hang out", it's better than Catania - not to find. There are a lot of restaurants, shops, night clubs, etc.
