Why settle for just one island while you’re here? Kefalonia lies just north of Zante and is big on beauty. First off, ride the ferry over to her shores, watching as her mountains and cliffs come into view. First on the agenda is a trip the Drogarati Cave. Step inside this 1,000 square-metre cavern and prepare to be dazzled by its stalactites and stalagmites. Your tour then continues to Melissani Lake - a subterranean lagoon only discovered in 1951. Take a rowboat over its waters - they turn an extraordinarily bright blue when the sunlight shines through the roof. After this there is time for lunch at the portside village of Agia Efimia, before a photo stop above Myrtos Bay. This cliff-framed beach took a starring role in the movie, Captain Corelli’s Mandolin. Lastly, we’ll drive past Argostoli on the way to our last stop at the Kastro of St. George, a ruined hilltop fortress that was once Kefalonia’s capital, before sailing back to Zante.
