2.Turtles, Marathonisi & Keri Caves Speedboat Tour

★★★★★★★★★★4.5 · 1,443 reviews · 150 minutes - 3 hours · from $29

Ride a small speedboat from Agios Sostis through Zakynthos Marine Park, looking for Caretta caretta turtles before entering Keri’s sea caves. You’ll stop to swim near a private beach and Marathonisi, pass Cameo Islet, and travel with an English or Greek-speaking captain such as Fred, Petros, or Pro.

“The boat trip was a fantastic experience! I would definitely recommend this as it was easy booking and a modern speed boat for 8 persons. Our guide FRED made it special as he really is a funny and trustful captain. He brought us not only to the Blue Caves, but also in them with the boat. Sounds weird? It is the truth. Unfortunately no turtle, but it is too late in the year.”
