What time does the sun set in Kefalonia in October?
In early October, the sun sets in Kefalonia at around 7:25 pm, and around 7:00 pm by mid-month. Clocks go back an hour on the last Sunday of October, so by the end of the month sunset is around 5:40 pm. All times are Greek local time. Evenings cool quickly after sunset, so bring a layer.

Can I visit Melissani Cave in October?
Usually, yes, though opening hours in October can be shorter than in summer, so check before you go. It's a good time to visit, with shorter queues. Its underground lake is explored by rowing boat and is at its most magical when sunlight pours through the open roof around midday.

Is October or November better for visiting Kefalonia?
