Marathonisi Caves, Zakynthos Travel Guide

The Marathonisi Caves are a collection of remarkable natural sea caves located on the coast of Marathonisi, an uninhabited island in Laganas Bay, Zakynthos. The island, also known as Turtle Island due to its shape, is a protected area within the National Marine Park of Zakynthos, playing a vital role in the reproduction of the Caretta Caretta sea turtle. Marathonisi boasts two main beaches: one with white sand and the other with pebbles. The pebble beach provides access to a large cave, while the sandy beach is a nesting site for the Caretta Caretta turtles. Visitors can explore the caves by swimming or boat, marveling at the rock formations and diverse marine life. The turquoise waters surrounding the island are ideal for snorkeling.Boat trips to Marathonisi and its caves are readily available from Laganas Bay, Agios Sostis, and Keri. These excursions often include turtle spotting and visits to nearby Keri Caves. As Marathonisi is a protected area, visitors should be mindful of the environment and follow guidelines to avoid disturbing the turtles or their nesting sites. There are generally no facilities on the island, so it's best to bring your own supplies.
