The Ionian Islands are not usually the first islands people think of when traveling to Greece. While Mykonos and Santorini take all the popularity, I believe the most stunning islands in Greece are in fact, the Ionian Islands. Corfu, also known as Kerkyra, must be the most scenic, beautiful, and adventurous island of them all. From day trips to uninhabited islands, partying until the morning, or cliff jumping into the clear waters, Corfu is a giant playground for everyone to enjoy.
