If you like fish, don’t miss Koiladhia. This is a working port and fishing is one of the two main occupations, so you can dine out on the local catch at one of several restaurants.
The other business in town is boat building and repairs, with a substantial boatyard dealing with a variety of craft, yachts included.
Koiladhia is a working town, rather than a tourist hub, so it’s not the prettiest place you’ll see. There is a certain honesty and friendliness about the place though and the handful of shops will cater for your basic needs.
Worth a visit are the Franchti Caves on the north side of the bay. These have yielded human skeletons going back to pre-historic times, including one believed to be the oldest in Greece.
