Where are you wintering now in Sardinia? If in Cagliari or along the western coast, I'd suggest you do a loop around Sicily's south coast. Sciacca is worth a stop for multiple reasons - just walking over to the
commercial fishing harbor and watching them start with huge tree trunks and end up building a 90'
fishing boat is fascinating - and it's located inbetween the two main Greek city states that were located in Sicily. And the comments about Siracusa is spot-on. Rarely do you hear cruising folks describe disappointment with visiting there. And then...assuming you make it to that point, a stop in
Malta is definitely worth considering because of its unique historic sites and multi-cultural/multi-ethnic
history. Of course, if you are on Sardinia's
east coast, the sirens of Italy are calling and doing a southern loop around Sicily won't appeal.
