Indulge in a half-day, rigorous guided tour via air-conditioned motorcoach to explore Cephalonia's underground. Enjoy a scenic drive across the breathtaking slopes of Mt. Ainos through the lush Greek countryside rich with vineyards, olive orchards, and cypress groves. Descend a manmade tunnel to the shores of Lake Melissani, the island's largest cave lake. Take a rowboat cruise to view the lake cave's dramatic stalactites and stalagmites that border its glistening aquamarine waters. Visit majestic Drogarati Cave, located nearly 200 feet below the surface. Take in the spectacular beauty of this two-million-year-old cavern that features stunning rock formations and a magnificent hall with perfect acoustics called "Sala of Apotheosis". Emerge from the depths of Cephalonia for some free time to explore the resort of Sami, a charming waterfront town lined with shaded restaurants, tavernas, and shops, which was the site of the film Captain Corelli's Mandolin.
