The southern part of Zakynthos blends wild landscapes with protected natural habitats, where turquoise waters meet soft sand, sea caves, and nesting grounds for the endangered Caretta Caretta turtles. This guide introduces eight must-visit beaches and coastal landmarks, each offering its own version of escape — from peaceful swimming coves to iconic cliffs and protected marine zones.
Keri Caves
Accessible only by sea, the Keri Caves are a series of natural arches and carved tunnels along the island’s southwestern coast. The water here is crystal-clear and unusually deep, ideal for swimming, snorkelling, or simply floating in silence. Early morning or late afternoon visits capture the best light and the fewest crowds.
Access: By boat from Keri, Limni Keriou, or Agios Sostis
Best for: Cave swimming, photography, peaceful exploration
Mizithres Cliffs
Towering and iconic, the Mizithres rocks rise dramatically from the sea, just south of Keri. This is one of Zakynthos’s most photogenic viewpoints. A small beach has formed beneath the cliffs in recent years, but the true experience lies in approaching the area by boat and taking in the scale and solitude.
Access: View from Keri Lighthouse or visit by sea
Best for: Sunset views, private boat tours, dramatic landscapes
Marathias Beach
A quiet, pebbled stretch of coast shaded by trees, Marathias is ideal for those looking to stay close to the water all day. There are no organised facilities — just calm, deep water and the sound of cicadas. For a more elevated view, the nearby Marathias viewpoint is perfect for photos or sunset picnics.
Access: By car, with limited parking
Best for: Privacy, snorkelling, low-intervention nature
Marathonisi (Turtle Island)
Shaped like a turtle and home to actual turtles, Marathonisi is part of the National Marine Park and one of the most symbolic sites on the island. Boats are allowed to approach but not dock on certain parts of the island to protect the nesting areas. The waters surrounding it are shallow, clear, and perfect for swimming.
Access: By boat from Agios Sostis, Keri, or Laganas
Best for: Nature lovers, turtle sightings, day trips
Cameo Island
Cameo is a small private island connected to the shore by a wooden bridge. Known for its charm and low-key atmosphere, it’s a popular spot for quick visits, sunset views, and Instagram-worthy backdrops. Though weddings are sometimes held here, it remains a peaceful stop in the early hours.
Access: By footbridge from Agios Sostis
Best for: Photos, short visits, couples
Gerakas Beach
One of the most protected beaches on the island, Gerakas is a vital nesting site for the Caretta Caretta sea turtle. Visitors are not allowed to bring umbrellas or place anything near the shoreline. What you’ll find instead is soft sand, gentle waves, and an atmosphere of respectful stillness.
Access: By car; part of the Zakynthos Marine Park
Best for: Nature-conscious visitors, families, turtle education
Casa Playa (Banana Beach)
Known for its wide sandy stretch and full beach facilities, Casa Playa at Banana Beach is ideal for guests looking for a more social, organised beach day. With sunbeds, beach bars, water sports, and clear water, it offers a complete beach club experience with just enough space to still feel comfortable.
Access: By car; parking and shuttle service available
Best for: Full-day beach experience, drinks, and activities
Daphni Nesting Beach
Daphni is another protected bay within the Marine Park, where access is limited during turtle nesting season. The beach is small, with soft sand and quiet, shallow water. Its peaceful setting and eco-conscious approach make it perfect for slow afternoons and respectful nature encounters.
Access: By car via unpaved road (4×4 recommended)
Best for: Undisturbed nature, quiet swims, conservation travellers
