Uncover the secrets of the underwater world of the National Marine park of Zakynthos with this glass bottom boat tour from Laganas. Stop to swim at the Keri Caves and visit the island of Marathonisi, which is a breeding ground for loggerhead turtles.

Hop aboard a comfortable boat in the Agios Sostis harbour in Laganas. Choose from a shaded seating area and a rear sundeck where you can work on your tan. Feel the wind in your hair as you glide across the water to the protected waters of the National Marine park of Zakynthos.

Go for a refreshing dip at the Keri Caves which are only accessible by boat. Have the option to swim inside the caves to admire the way that blue light plays off the limestone walls.

Continue on to the island of Marathonisi and take in views of pine, olive and green oak forests as you approach. See the small beach where endangered Caretta Caretta turtles (loggerhead) lay their eggs.

Have free time on the island to explore or visit a bar where you can purchase snacks, drinks, and ice cream. Return to your meeting point at the end of your tour with unforgettable memories.
