I visited Santorini in November, and it was absolutely stunning. The city was nearly empty, making it a calm and peaceful experience. I went to Oia (the most beautiful town), Fira, the Red Beach (amazing, but watch your step!), the Black Beach, and the Akrotiri Lighthouse, which offers a breathtaking view. You must try the kebab at Metaxi Mas restaurant - everything was incredibly tasty!
