Marathonisi and Keri Caves: Zakynthos’ Natural Side

A cruise to Marathonisi Island and Keri Caves offers calm scenery, natural beauty and beautiful waters for swimming.

Marathonisi, also known as Turtle Island, is one of the most loved destinations for boat trips in southern Zakynthos. The area combines sandy beaches, clear waters and a peaceful natural setting. Keri Caves add a more dramatic character to the route, with rocky formations, sea passages and excellent swimming spots. A private cruise here is a great choice for families, couples and travelers who want a more relaxed experience, away from the busier pace of the island’s most famous landmarks.
