Sand and pebble, which is the whole decision
Our own beach guide splits them plainly:
- Sand: Skala, Makris Gialos and Platis Gialos at Lassi, and Xi over on the Paliki peninsula.
- Pebble: Myrtos, Antisamos, Petani, Fteri.
Myrtos is the one on the postcards and the one people picture when they book. It is pebble. That is not a reason to skip it, but it is a reason not to base a family week on the assumption of sand.
The bases
Lassi is Argostoli’s beach suburb, five to ten minutes over the hill, with the island’s easiest sandy pair in Makris Gialos and Platis Gialos. It is the family and first-timer default, and the sand matters more than it sounds, because the north of the island is pebble country.
Argostoli is the capital, about fifteen minutes from the airport, and the natural pick if you will not have a car - it is the bus and excursion hub and has year-round life, though it is a working town rather than a resort.
Skala, in the south-east corner, has around 3 km of sand and suits a beach-led week from the far corner.
Sami is the sightseer’s base - Melissani and Drogarati on the doorstep, Antisamos ten minutes away, and the Ithaca ferry leaving from the harbour in front of your breakfast table. It is not a sand base.
Where to stay in Kefalonia covers all of them.
You will almost certainly need a car
Effectively yes, is our own guide’s answer. The island is the largest in the Ionian, its sights sit on three different coasts an hour of winding road apart, and buses are thin and shaped around package schedules.
With children that changes the calculation twice over: the driving is real, and the alternative is being limited to whatever your base can reach. Argostoli and Lassi are the two bases that give you a genuine car-free fallback, which is why they suit a first family trip.
The Paliki quiet win
The short ferry from Argostoli to Lixouri works as a shortcut across the gulf, and beyond it wait Xi’s shallow red sand and the pale cliffs of Petani. Most guides skip the Paliki entirely, which is exactly why it stays calm in August.
For a family, the combination of a short boat, a shortcut and shallow sand on the other side is a better day than it looks on a map.
The caves, which are the day children remember
Melissani is a sunlit underground lake, and Drogarati the cave beside it - both near Sami and close together. They are the island’s set-piece and the reason Sami works as a base if the caves and the Ithaca day trip are what you came for.
Things to do in Kefalonia covers them, and the Kefalonia itinerary sequences the week.
What this page will not tell you
It will not tell you a beach is safe or suitable for your child. Pebble and sand are descriptions of a shore, not ratings - read the flags and the local advice rather than a guide on the day. Nothing here is a certification; our editorial policy says so plainly.
Our Kefalonia guide has the practicalities and Greece with kids covers choosing the island.
