It’s the biggest resort in Kefalonia and tends to be very busy in the summer, which is why it’s worth packing some extra layers and travelling in winter to beat the crowds. The Mediterranean climate is still mild in winter but there’s a good deal of rain, so you’ll have to pack an umbrella and check the forecast daily.

On a good day, temperatures will often climb to 15°C, which is lovely and mild for a quiet walk around the resort.
