My husband and I are coming to Sicily for the weekend and staying in Catania. We are arriving in the morning on Friday and staying until Sunday afternoon. We are doing a wine tasting tour on Saturday which will take the duration of the day. We were trying to figure out what we should do to maximize our time on Friday and Sunday morning. We are in our twenties, like to see historic and touristy sights, but also like some less common/more unique and remote ideas as well.
