I'm holidays in Kefalonia for a week this summer holiday with my two children. We won't be hiring a car and will be staying very close to the airport on the west side of the island in a hotel offering bed and breakfast. It has a pool, a bit of entertainment (games room etc) and is close to the beaches. I always like to visit the main centre and gather we can easily get a bus there, but if not I'd just get a taxi.
I know there are some quaint places and different beaches all round the island, and the harbour offers view of turtles if you get the timing right. But other than that, I'm wondering if there is anything you would consider a must-see or can't leave without experiencing, or the complete opposite (ie, don't bother with this or that).
Any helpful information would be gratefully received!
