Zákynthos (Zante), lies in the Ionian Sea, only 16 kilometers off the west coast of the Peloponnese. While the island's northwest coast has steep cliffs plummeting down to rocky shores with white pebble beaches and crystal clear turquoise seas, the south is flatter with golden sand beaches.
Zákynthos Town (Zante Town)
On the island's east coast, extending in a wide arc along the gently sloping shores of a bay, Zákynthos Town is the capital of Zákynthos. Many of its Neoclassical buildings were demolished by the 1953 earthquake, but its paved streets and squares, filled with bakeries, cafés, boutiques, and jewelry stores, are still a joy to explore on foot. The town's main church, Agios Dionysios, which houses the relics of the town's patron saint, dates from 1708 and was reconstructed in 1954. For spectacular views over town and the port, go up to the village of Bohali (2.5 kilometers) to the ruined Venetian castle, set in a park with pine trees. This attraction was also largely destroyed by the earthquake, but you can still see the main gate (bearing the Lion of St. Mark, the symbol of Venice), the outer walls, and battlements.
Shipwreck beach (Navagio beach)
Probably the most photographed beach in Greece, and also featuring in many Greek National Tourism Organisation advertisements, Shipwreck Beach lies in the so-called Smuggler's Cove on Zakynthos' west coast. Made up of fine white pebbles backed by cliffs, the beach takes its name from the wreck of a rusty ship that was transporting contraband cigarettes and was washed up here in 1980. The beach can only be accessed from the sea - you can take a taxi-boat from the harbor at Agios Nikolaos (on the northeast coast, 32 kilometers from Zakynthos Town) or visit it as part of a round-the-island one-day boat excursion from Zakynthos Town, offered by many tour operators. The beach does get extremely busy in peak season, but is quieter after 3pm when the day trippers leave.
Keri Caves
On the southwest coast, 14 kilometers from Zákynthos Town, close to the village of Kerí, a row of dramatic caves opens directly onto a crystal clear turquoise sea. It's possible to visit the caves as part of an organised excursion, or rent a boat and go independently. You can swim into the caves and snorkel or dive to see the amazing lighting effects as the sun reflects through the water and onto the cave walls.
Blue Caves
On the northern tip of the island, at Cape Skinari, you'll find the most spectacular so-called Blue Caves. Inside, the bright blue sea reflects the color of the sky, which is mirrored off the walls of the caves and creates magical azure and sapphire light. You can visit the Blue Caves in a small glass-bottom boat, which departs from Agios Nikolaos (on the northeast coast, 32 kilometers from Zakynthos Town), or as part of the longer round-the-island cruise from Zakynthos Town.
Zakynthos National Marine Park in Laganás Bay
On the southeast coast, eight kilometers south of Zákynthos town, the wide bay of Laganás is home to several blissful stretches of sandy beach. Since the 1980s, it has been the island's top resort, with budget accommodation attracting young visitors in search of sea, sun, and fun. However, locals are now being encouraged to develop eco-tourism here, as Laganás Bay is the breeding area for the loggerhead sea turtle (Caretta caretta). An endangered species, this timid creature lays its eggs in the sand in summer, and there are an estimated 1,300 loggerhead turtles living around the bay. In 1999, the Zakynthos National Marine Park was founded to protect wildlife in Laganás Bay and to limit access to certain areas of beach during the nesting season.
