The third largest of the Ionian isles, Zakinthos is green and fertile, boasting 7,000 species of flowers. In the town, visit the Byzantine museum with its collection of 15th to 17th-century icons and frescoes rescued from buildings damaged by earthquakes which leveled most of the Venetian architecture that previously predominated. There are a number of distinctive churches, including the Agios Dionysios honoring the island’s patron saint, located very ear the harbor. Many visitors opt for boat tours to one or more of the enchanting grottoes along the coast, known locally as Blue Caves for the glowing light within. Shipwreck beach, an iconic image of the Greek Isles, is a sliver of white sand between high cliffs, decorated by its namesake hulk, accessible only by sea but also viewable from a platform 600 feet above. There are a variety of other beaches, both sand and gravel, accessible by road.
