Explore Greek culture and natural formations at Melissani, known in Greek mythology as the cave of the nymphs, and a 13th century monastery. Ride in a wooden boat on the deep-blue waters of Melissani’s subterranean lake. The Agios Andreas Monastery is said to house an unusual holy relic — the foot of the Apostle Andrew. Continue to the quaint fishing village of Agia Efimia, exploring its charms on your own before returning to the ship.
