Relaxing vibe with Ioneon travel, beautiful coast, splendid beaches - must do activity during Zakynthos vacation!
Maximum 10 people. A small-group expedition through the entire Keri Cave system to the dramatic Eros Cave. Three swimming stops. Access to places that larger group boats simply cannot reach.
Unlike standard Marine Park tours that stop only at the first arch, the Eros Cave tour passes through the entire Keri Cave network — arch by arch, chamber by chamber. With a maximum of 10 people, you access places that larger boats cannot reach, including swimming inside Eros Cave itself.
The Eros Cave tour involves swimming inside a cave and is best suited to confident swimmers. Children are welcome but must be accompanied and supervised at all times.
Departures from Agios Sostis harbour, South Zakynthos.
From Kalamaki / Airport: ~5 min by car · From Laganas: ~10 min
