4.9

Located on the southwestern coast of Zakynthos island, the Keri Caves are a collection of remarkable sea caves sculpted by the elements over thousands of years. Situated along the coastline between Kapo Marathia and the Mizithres rocks, the caves derive their name from the Keri area. These natural grottoes are a highlight of Zakynthos, offering visitors a chance to witness the raw beauty of the Ionian Sea. The Keri Caves feature a variety of formations, with some caves large enough to enter by boat and others accessible only by swimming or kayak. The crystal-clear waters inside the caves take on a mesmerizing blue hue, rivaling the famed Blue Caves of Zakynthos. This vibrant color is created by the reflection of sunlight on the limestone walls and, in some cases, by underwater windows. Visitors can explore the caves by boat tour or private boat, often departing from Agios Sostis or Laganas Bay. Many tours combine a visit to the Keri Caves with other attractions, such as Marathonisi (Turtle Island) and opportunities for spotting loggerhead sea turtles. Snorkeling and swimming are popular activities, allowing visitors to fully appreciate the clear waters and marine life. The area is also known for its dramatic cliffs, rock arches, and small beaches, providing ample opportunities for photography and exploration. Beyond the caves themselves, the surrounding area offers additional attractions. The village of Keri provides panoramic views of the coastline, while the Keri Lighthouse offers stunning sunset vistas. The Mizithres rocks, two distinctive crags rising from the sea, are another notable landmark.
