Late September and all through October are my favourite time of year in Greece. Our village is in the South East Peloponnese and it's perfect that time of year, the weather is great, not too hot, most of the tourists (and locals!) have left the beaches and the sea temperature is at it's best 😊
We will be visiting the islands this October & I can't wait. We've been to Sparta & Kalamata in the fall & it was absolutely beautiful. The drive thru the mountains was an experience to say the least in our little rental car! I can't wait to experience your beautiful country again.
